302 stainless steel

302 stainless steel wire is an international labeling methods. 302 stainless steel --S30210 (US AISI, ASTM) characteristics and uses: The cold has a high strength, elongation, but somewhat less than 1Cr17Ni7. Building decorative component. International Stainless Steel labeling methods.
American Iron and Steel Institute with three digits to indicate a variety of standard grade stainless steel malleable.
Among them:
① austenitic stainless steel lined with 200 and 300 series of numbers.
② ferritic and martensitic stainless steel 400 series is represented by a number. For example, some of the more common austenitic stainless steel
Is 302, 304, 316 and 310 marks.
③ ferritic stainless steel is marked 430 and 446, 410, 420, and 440C martensitic stainless steel is a scalar
Hutchison, duplex (austenitic - ferritic).
④ stainless steel, precipitation hardening stainless steel and high alloy iron content of less than 50% usually uses proprietary name or trademark name.
Steel symbol and representation
① chemical element with the symbol of international and national symbols to represent the chemical composition, using the Arabic alphabet to represent the content:
Such as: China, Russia 12CrNi3A.
② with a fixed number of digits to represent the steel type series or digital; such as: USA, Japan, 300 series, 400 series, 200 series.
③ composition of the Latin alphabet and the order number, saying only that purpose.

The use of stainless steel wire

Stainless steel wire use is divided into: spring steel wire (commonly steel 302,304,316 and 631), cold top with a wire (430,410,304M, 304HC, 302HQ, 316 and 305), wire (ER308, ER309 and ER321) precision shaft with a wire (420J2,4Cr13 and 303), netting wire (430,304,316 and 310), Stainless steel weaving wire with a wire rope (304,316), and 302 stainless steel wire for general purpose wire, such as Nail, cleaning ball bundled wire, drawn wire filament (405,410,430,430L, 304,04HC and 316, etc.). 302 stainless steel wire energy saving and environmental protection, with high corrosion resistance, stainless steel wire rod high elasticity and toughness. Preparation methods and advanced technology and simple, low production costs.

316 stainless steel wire 302 stainless steel wire drawing process and process characteristics

  Stainless steel as raw material produced all kinds of different sizes and types of silk products, the common good corrosion resistance, high cost of stainless steel wire is 304 and 316 stainless steel wire.
 316 stainless steel wire drawing, the role of the pulling force of the rod or wire drawing die blank from the die hole pulled out to steel or non-ferrous metal production line of small section of Stainless Steel Wire  plastic forming process. A variety of different cross-sectional shape and size of metal wire metals and alloys can be produced using the drawing. Pull the 304 stainless steel wire, accurate dimensions, smooth surface, and drawing equipment and tooling used in a simple, easy to manufacture.
   Metal wire drawing 304 stainless steel wire state is three to two main stress has been tensile stress to compressive stress, which are compressed with the three main stress state to stress compared to being drawn metal wire easier to achieve plastic Stainless steel wires  state. The deformed state is drawn into the compression deformation of the second deformation 304 stainless steel wire 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 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.
