stainless steel fine wire's Process characteristics
Metal wire drawing stress state for two to stress was tensile stress to three principal stress state, and it is three to compress the main stress state of stress was compared, the metal wire drawing easier to reach the state of plastic deformation. The deformation state of the drawing is two, the compression deformation is always the three main deformation state of the tensile deformation, which is disadvantageous to the plasticity of the metal material, and it is easy to produce and expose the surface defects. The deformation of wire drawing process is limited by its safety factor, and the number of drawing passes is smaller when the secondary deformation is smaller. Therefore, multi pass continuous high-speed drawing is often used in the production of wire.
stainless steel fine wire's type
In general, according to austenite, ferrite, two-way stainless steel and martensitic stainless steel, mainly divided into 2 lines, 3 series, 4 series, 5 series and 6 series stainless steel.
316 and 317 stainless steel (see below the performance of 317 stainless steel) is a stainless steel containing molybdenum. The molybdenum content in 317 stainless steel with 316 stainless steel. Due to a little of molybdenum in steel, the steel overall performance is better than 310 and 304 stainless steel, high temperature, when the concentration of sulfuric acid is less than 15% and more than 85%, 316 stainless steel has been widely used. 316 stainless steel also has good resistance to chloride corrosion, so it is often used in marine environments. The maximum carbon content of 316L stainless steel is 0.03, which can be used in welding and can not be annealed and requires maximum corrosion resistance
