301 stainless steel coil, 301 stainless steel chemical composition, imported 301 stainless steel, 301 stainless steel hardness 
301 stainless steel band 301 is 1Cr17Ni7. Stainless steel is rust-proof mechanism alloying elements form a dense oxide film, isolated from contact with oxygen, prevent further oxidation. Therefore, stainless steel is not "stainless." 301 stainless steel: 301 stainless steel grades 1Cr17Ni7. Chemical composition% C: ≤0.15, Si: ≤1.0, Mn: ≤2.0, Cr: 16.0 ~ 18.0, Ni: 6.0-8.0, S: ≤0.03, P: ≤0.045 301 (17Cr-7Ni- carbon) material: with compared to the 304, Cr, Ni content of less tensile strength and hardness increased during cold, non-magnetic, but the cold is magnetic. Uses: trains, aircraft, conveyors, vehicles, bolts, springs, sieve. Note: L behalf of low-carbon, such as 304L low carbon content than 304. H and S stands for high temperature, such as the 310S stronger than 310 high temperature resistance, 304H than 304 heat.
