304 stainless steel wire 316 stainless steel wire Introduction

304 stainless steel wire, also known as stainless steel wire, 304 stainless steel wire as raw material production, cross-section is generally round or flat. Common good corrosion resistance, high cost is 304 and 316 stainless steel wire stainless steel wire. Under the action of the pulling force of the rod or wire drawing die blank from the die hole pulled out in order to produce metal wire or plastic processing small section of non-ferrous metal wire. A variety of different cross-sectional shape and size of metal wire metals and alloys can be produced using the drawing. Pull the Stainless steel wire , accurate dimensions, smooth surface, and drawing equipment and tooling used in a simple, easy to manufacture. Metal wire drawing stress state is three to two main stress has been tensile Stainless Steel Shaped Wire to compressive stress, which are compressed with the three main stress state to stress compared to being drawn metal wire easier to achieve plastic deformation state. The deformed state is drawn into the compression deformation of the second deformation state to the primary three tensile deformation has been the state of the plastic material, a metal negative play, more prone to surface defects and exposure. Metal 304 stainless steel wire drawing process, the amount of deformation pass safety factor by its restrictions, the smaller the amount of the drawing pass deformation pass more, so often used in the production of wire consecutive multi-channel high-speed drawing.304 stainless steel wire, 316 stainless steel wire surface bright, beautiful and durable, anti-corrosion, acid and alkali, high temperature, easy to wear, easy to aging, good toughness, strength. Widely used: to weave woven wire mesh, crimped wire mesh, hexagonal wire mesh, conveyor belt, stainless steel wire rope, handicrafts, cutlery rack, and a variety of woven wire meshes, twist flowers, bundled and other purposes.

304 stainless steel food-grade stainless steel

304 stainless steel is suitable for use in food processing, storage and transportation. Has good processing properties and weldability. Plate heat exchanger, bellows, household goods (1,2 tableware, cabinets, indoor pipes, water heaters, boilers, bath), auto parts (windshield wipers, muffler, mold products), medical equipment, building materials, chemical, food industry agriculture, ship parts, and so on. 304 stainless steel wire is a nationally recognized food-grade stainless steel.
surface quality is good or bad, depends mainly on the pickling process after heat treatment, a heat treatment if the first step of the surface oxide formed thick skin or tissue is uneven, it does not improve with pickled surface smoothness and uniformity. So to pay full attention to the heating surface cleaning or heat treatment before heat treatment.
If the thickness of the stainless steel oxide surface unevenness, thick and thin places where the underlying substrate metal surface finish is different, surface and pickling and surface oxide scale dissolution of the base metal attachment site is the extent of acid erosion different, therefore, the steel sheet surface is not uniform. Therefore, when the heat treatment is heated, so as to form an oxide skin must be uniform. To meet this requirement, you must pay attention to the following issues:
If the stainless steel plate attached to the surface of the workpiece during heating oil, the site of attachment of the scale thickness and the scale and the thickness of the other portion of different composition, and will produce carburizing. Subcutaneous base metal oxide is partially cemented will seriously eroded acids. When the combustion of heavy oil burner initially discharged droplets, if attached to the workpiece, a great impact. Operating heavyweight fingerprints attached to the workpiece when will be affected. Therefore, the bath as high officials do not touch the stainless steel parts, do not make a new piece stained with oil. The gloves must Daiqing Jie.
If the surface during cold lubricants attached, must be fully cleaned with warm water and then skim trichlorethylene degreasing agent, caustic soda solution, and then subjected to heat treatment.
If the surface of stainless steel plate with debris, especially when attached to a piece of organic matter or gray, heating certainly will affect the scale.
Differences stainless steel plate of the furnace atmosphere in the furnace atmosphere locally different, oxide scale formed will have a change, which is caused by uneven pickled reasons. Therefore, at the time of heating, atmosphere in the furnace of the various parts must be the same. To do this, you must also consider the atmosphere of the cycle.

304 stainless steel is a versatile stainless steel material

304 stainless steel is a versatile stainless steel material, anti-rust performance than the 200 series stainless steel stronger. Also relatively good high temperature, the general temperature limit is less than 650 ℃. 304 stainless steel with excellent resistance between the resistance and good resistance to intergranular corrosion. For oxidizing acid, in the experiment: the nitrate concentration ≤65% below the boiling temperature of 304 stainless steel wire with strong corrosion resistance. Most of the alkali solution and organic and inorganic acids also have good corrosion resistance.

The reason 304 stainless steel rust phenomenon occurs

304 stainless steel wire 304 reasons appear rusting stainless steel rusting occurs, there may be several reasons:
1. Chloride
Widespread presence of chloride ions, such as sodium chloride / sweat / sea / sea / soil, and so on. Stainless steel in the presence of chloride ions in the environment, corrosion and soon, even more than the ordinary low carbon steel. Therefore, the use of stainless steel environment requirements, and require frequent cleaning to remove dust, clean and dry. (So that you can give him set a "misuse.") The United States is an example: a company with an oak containers with a solution of chlorine ions, the container has been used hundreds of years, plans to replace the nineties due to lack of modern oak material, the use of stainless steel replacement 16 days after container leak due to corrosion.
2. Solution treatment
No alloying elements dissolved in the matrix, resulting in tissue matrix alloy content is low, poor corrosion resistance.
3. intergranular corrosion
This material does not contain titanium and niobium have a tendency to intergranular corrosion. Adding titanium and niobium, which together with the stabilization process can reduce intergranular corrosion. In the air or chemical corrosion medium can resist a high-alloy steel, stainless steel is a beautiful surface and good corrosion resistance, without going through the plated surface treatment, play inherent in the surface properties of stainless steel, for use in multi-an aspect of the steel, commonly referred to as stainless steel. Representative of the performance of 13 chrome steel, chrome-nickel steel alloy 18-8. From the metallographic point of view, because the stainless steel contains chromium chromium film formed on the surface leaving a thin, the membrane separating oxygen from invading the inner steel corrosion effect. In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium. The need for welding applications. Lower carbon content makes it close to the weld heat affected zone to minimize carbide precipitation, and carbide precipitation may lead to intergranular corrosion of stainless steel in some environments (welding erosion).
4. appearances
Refers to the phenomenon of surface marks 304 stainless steel deep processing or processed products after grinding, wire-bound pit marks or dot defects in the product surface.
The reason: the surface, the mold surface of a foreign body, blank pad surface scars.
Solution: Before processing to remove the foreign body, the scars can also be removed by thoroughly grinding and orange peel.
Orange peel refers to the molded article 304 in the polishing or other cases, the surface of the same shape as the orange peel phenomenon.
Cause: The grinding is not sufficient, the more severe the greater processing orange peel, raw coarse grains, heat softened.
Solution: deep processing products are fully ground, select the appropriate heat treatment conditions, controlling the grain size of raw materials.

General characteristics of 304 stainless steel

Most of the long-term requirements of maintaining the original appearance of the building. In determining to choose the type of stainless steel, the main consideration is the aesthetic standards required by the system to be used to clean the corrosion and the location of the atmosphere. However, a growing number of other applications, or just looking for the integrity of the structure is not permeable. For example, industrial building roof and side walls. In these applications, the construction cost of ownership may be more important than the aesthetic, the surface is not very clean and can be. Effect of using 304 stainless steel wire in dry indoor environment is quite good. However, in rural and urban outdoors in order to maintain their appearance, they need regular cleaning. In heavily polluted industrial areas and coastal areas, the surface will be very dirty, and even rust.
But to get the aesthetic effect of the outdoor environment, it requires the use of nickel-containing stainless steel. So, 304 Stainless Steel Binding Wire is widely used in curtain wall, side walls, roofs and other construction purposes, but in severe erosion of industrial or marine atmosphere, the best use of 316 stainless steel. Stainless steel sliding door, it has been fully aware of the use of stainless steel in structural applications superiority. There are several design criteria are included in the 304 and 316 stainless steel. Because "duplex" 2205 has already good resistance to atmospheric corrosion and high tensile strength and elastic limit of integration, so that the European criteria also included the steel. In fact the shape of the product, stainless steel is the whole shape and size of the standard metal manufacturing, and there are many special shapes. The most commonly used products are made with sheet and strip, and plate production with special products, for example, the production of hot-rolled structural steel and structural steel extrusion. And there are round, oval, square, rectangular and hexagonal welded or seamless steel tubes and other forms of products, including profiles, rods, wire and castings.

Plate heat exchanger, bellows, household goods (1,2 tableware, cabinets, indoor pipes, water heaters, boilers, bath), auto parts (windshield wipers, muffler, mold products), medical equipment, building materials, chemical, food industry agriculture, ship parts, and so on. 304 Stainless Steel Binding Wire is a nationally recognized food-grade stainless steel.

Standard 304 stainless steel product requirements

   304 stainless steel is the most important element of Ni, Cr, but it is not limited to these two elements. Specific requirements prescribed by product standards. Industry conditions as long as the common determination Ni content of more than 8%, Cr content greater than 18%, it can be considered a 304 stainless steel. This is why the industry will be called 18/8 stainless steel such reasons. In fact, the relevant product standard 304 has very clear rules, and these products have some differences in standards for different shapes of stainless steel. Here are some common product standards and testing.
To determine a material is not 304 stainless steel, the product must meet the standard requirements of each element, as long as one does not, can not be called 304 stainless steel wire.

304 stainless steel

304 stainless steel wire 304 stainless steel is a very common stainless steel, a density of 7.93 g / cm3, the industry also called 18/8 stainless steel. Its high-temperature metal products, processing performance, it is widely used in industrial and medical furniture industry and the food industry.
Common ground marking methods have 06Cr19Ni10, S30408, SUS304 three, including 06Cr19Ni10 generally expressed GB standard production, S30408 generally expressed ASTM standards, SUS 304 Japanese standard labeling standard.
304 is a versatile stainless steel, it is widely used to produce good overall performance requirements (corrosion resistance and formability) of equipment and parts.

Use stainless steel wire rope

Stainless steel wire rope with a plurality of thin stainless steel wire or multi-strand twisted rope flexibility in material handling machinery for lifting, pulling, tensioning and load-bearing purposes. High strength 304 stainless steel wire rope, light weight, smooth, easy to suddenly break the whole root, reliable work.

Stainless steel wire rope use is:

1, non-direct high-speed, heavy load use.

The new stainless steel wire supplier rope not immediately in high-speed, heavy load directly, but to be a period of time at low speed, medium-load conditions, adapt to the use of the new state after the rope, wire rope and then gradually increase the speed and increase the lifting load.

2, is strictly prohibited quit.

Combined with the use of stainless steel wire rope pulley, it must be taken to prevent the rope from the wheel out of the slot. If the rope off the wheel groove after continued use, the rope will have kinks, broken wires, broken stocks, etc., prone to accidents.

3, non extrusion.

When using stainless steel wire rope can not be strongly pressed to avoid rope deformation, resulting in structural damage and broken wires appear early, or even broken rope off shares, significantly reduce the service life of the rope.

4, is strictly prohibited high-speed operation and other objects friction.

At high speeds, the wire rope and the instant when the frictional heat generated by the movement of objects to each other these may lead to emergence of martensite steel surface, which is the main reason for causing early wire breakage.

5. Do scattered wound.

When the stainless steel wire rope wrapped around the drum, should neatly as possible. If scattered wound, the rope at work due to squeezing each other will lead to destruction of the rope structure, resulting in an early broken wire, rope directly affect life.

6, prohibited the use of overload.

Stainless steel wire rope overload will increase its use by extrusion extent, the degree of wear and external wire round match between the grooves between the internal wire, shortening the life of the pulley.

7. Do a dramatic impact.

Several attacks can seriously shorten the life of the rope, the impact load overload the pit directly lead rope break.

8, in use should be done not wet.

Should be possible to use stainless steel wire in a dry environment. Easy to rust under the conditions of use of galvanized steel wire rope.
