Two stainless steel wire coiled stainless steel wire process is processing a variety of standard parts, machinery shaft parts, cold-drawn steel and metal products in the main material. In the United States, Japan and other countries in the production of stainless steel wire about 8% to 9%. Stainless steel in the forming and heat treatment process, the surface will produce a layer of black oxide, such oxide compact structure, and the substrate adhesion, comprising Fe, Cr, Ni, small amounts of C and Si, there may be Mn, Ti, Mo and W and other elements, oxides structure: ferrous oxide (FeO), iron oxide (Fe2O3), iron oxide (Fe3O4), chromium oxide (Cr2O3), nickel oxide (NiO), silicon dioxide (SiO2) chrome spinel (Cr2O3 # FeO) and spinel nickel (Ni # Fe2O3) and so on. Stainless steel oxide destroys the aesthetics of the steel surface, will accelerate the electrochemical corrosion of metal surfaces Huizhou stainless steel wire, and surface stress its presence will accelerate stress corrosion of steel surfaces. Therefore, the stainless steel surface oxide must be removed prior to subsequent processing and clean. Stainless steel flexible wire and properties of austenitic steel series (Cr-Ni) stainless steel cord has a very good corrosion resistance, but such large deformation resistance of steel, cold strengthening fast, is not conducive to the cold upsetting. In order to improve the performance of cold heading, the main measures are: 1) to reduce the carbon content in steel Guangzhou stainless steel wire, reducing the deformation resistance of steel, such as 316L. 2) to increase the Ni content in steel to improve austenite stability, to prevent or reduce the generation of deformation martensite during cold heading, cold strengthening slowing the speed, such as 304M (M represents a middle hardening rate). 3) increase in steel Cu reduces the deformation resistance of steel, reinforced cold slows the speed, which greatly improved the performance of deep drawing and cold heading steel. 4) coarse crystal grains, as compared with more than 10 fine grain, coarse grained steel wire tensile strength, slightly lower yield strength, greater elongation, reduction of area increases, performance is greatly improved cold heading shiny stainless steel wire, can withstand greater cold deformation without cracking. 5) reduction in nitrogen, silicon and other solid solution strengthening element of stainless steel wire, the solution heat treatment will reduce the hardness. To BT304C1 correspondence between carbon content and tensile strength. When the lower the carbon content, the lower the tensile strength index, this trend performance significantly. BT304C1 carbon content at about 0.03% to improve the tensile strength of the effect is obvious.
