Stainless steel are the following: Model 301 - scalability specializing in the production of stainless steel jewelry line for molding products. It can also be rapidly hardened by mechanical processing. Good weldability. Abrasion resistance and fatigue strength than 304 stainless steel. 302 Model 304 with corrosion resistance manufacturing stainless steel braided lines, due to relatively high carbon intensity and therefore better. Model 303 - by adding a small amount of sulfur and phosphorus to more than 304 cutting. Model 304- general model; that is 18/8 stainless steel. GB grades 0Cr18Ni9. Model 309 - 304 - better temperature resistance. How to identify the stainless steel wire rope (a) many measures and methods of manufacture of certain products in the industry, will use the materials for the production of stainless steel wire rope, stainless steel in order to identify and shoddy cheap sale of stainless steel jewelry line, can take. But many customers do not know what method can distinguish, for everyone listed below are several identification methods. 1, the magnetic testing method Magnetic test method is the most primitive of the most common of the easiest way to distinguish between austenitic stainless steel and ferritic stainless steel, austenitic stainless steel is non-magnetic, but after the high-reduction cold working after having mild magnetic; and pure chrome steel and low alloy steels are strongly magnetic. 2, a notable feature point nitrate test method for stainless steel wire rope is concentrated nitric acid and dilute nitric acid has inherent corrosion resistance, this performance so that it can easily be distinguished from most other metals or alloys.
