Description:
301 is a versatile stainless steel, it is widely used to produce good overall performance requirements (corrosion resistance and formability) of equipment and parts. 301 stainless steel is produced in accordance with the American ASTM standard stainless steel grades. The 301 is the most widely used stainless steel, heat resistant steel. 301 (17Cr-7Ni-carbon) material: 304 steel, Cr and the Ni content increased tensile strength and hardness when cold working, non-magnetic, but cold working magnetic.
SUS301 (17Cr-7Ni) stainless steel with high strength can be obtained after the cold working. SUS301 stainless steel for railway vehicles, conveyor, bolts and nuts, spring.The SUS301 contrast to the common steels, excellent high temperature strength, fatigue strength and corrosion resistance, the use of the tram to achieve light weight.Stainless steel will rust, rust-time speed of specific look at the environment: wet, acid-base and strong air environment rust faster seaside rust faster than inland.
Depends on the material of stainless steel, rust-proof function is mainly from the nickel, according to the level of the nickel content is divided into several models: from low to high order # 201, # 202, # 301, # 304.
