Stainless steel raw materials: molybdenum development

The main areas of consumption of molybdenum in the steel industry, the industrialized countries more than 80% of molybdenum as an added element of steel, only about 20% of the molybdenum metal used to produce molybdenum, super alloys and special alloys, chemicals, etc., consumed in oil chemical industry, light industry, electronics and some high-tech areas.Molybdenum and molybdenum alloy rods (bars), wire, sheet, strip, foil and shaped products commonly used in metallurgy, machinery manufacturing,stainless steel wire electronics, lighting and some high-tech fields. Stainless Steel Shaped Wire The illumination filament stent mandrel wire, reflective screen; electronics industry with an anode, a gate and an auxiliary electrode, gasket; vacuum plating, sputtering with the container, a boat, a heater; heat generating element used in a high temperature furnace electrodes, heat shields; surface treatment used for welding, spraying; thermocouple and temperature with protective cover; UO2 refining was burned by boat and so on. The last 10 years, the application of molybdenum was given a further expansion, such as molybdenum powder or molybdenum wire thermal spraying greatly improves the life of the piston rings and gear parts on the car; in glass and fire-resistant fiber material industry, molybdenum can be replaced previous platinum crucibles and electrodes, and achieved great results. The emergence of high-temperature molybdenum, mercury and molybdenum in a vacuum oven halogen range of applications is growing.Stainless steel wires In die-casting industry, molybdenum and alloys can be used as non-ferrous and ferrous metal casting mold material. Molybdenum-based ceramic heat pipe suitable for BOF steelmaking process of continuous measurement of the casing, hot extrusion die; molybdenum alloys are widely used to wear head seamless steel and stainless steel pipe system, significantly improve productivity and product quality, reduce costs. Molybdenum and tungsten alloy formation, its anti (liquid zinc and zinc vapor) particularly excellent corrosion resistance, has generally produced using Mo-30W alloy casing vertical and temperature, greatly reducing maintenance downtime, improve working conditions. MoSi2 oxidation resistance particularly good, use it as a working temperature up to 1700 ℃ heating elements in the atmosphere, but also as a rare earth smelting and some single crystal pulling crucible, instead of precious platinum crucible.

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 Stainless steel wires 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, Binding 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.

Stainless steel wire

Stainless steel wire, also known as stainless steel wire, stainless steel as raw material made of various types of different sizes and types of silk products, the origin of the United States, the Netherlands, Japan, the cross-section is generally round or flat. Common good corrosion resistance, high cost is 304 and 316 stainless steel wire stainless steel wire.
Stainless steel wires drawing (stainless steel wire rod drawing) under the action of the pulling force of the rod or wire drawing die blanks from the die orifice is pulled to the production of steel or non-ferrous metal wire small section of metal plastic processing. A variety of different cross-sectional shape and size of wire and metal alloys may be employed drawing production. Pull the wire, the precise size, smooth surface, and drawing equipment and tooling used in simple, easy to manufacture.
Process of drawing deformation index
Wire drawing process in increasing the length of the cross section is reduced, before drawing, after the wire cross-sectional area and length, respectively, F. , F and L. , L represents.
