The difference between plain 202 stainless steel and food grade 202 stainless steel
202 stainless steel is one of the 200 series stainless steel, the national standard model is 1Cr18Mn8Ni5N. 200 series stainless steel is low nickel, high manganese stainless steel, nickel content, manganese content of about 8%, is a nickel type stainless steel.
Stainless steel is often divided into martensitic steel, ferritic steel, austenitic steel and so on according to the state of the organization. In addition, can be divided into components: chromium stainless steel, chromium nickel stainless steel and chromium, manganese, nitrogen, stainless steel and so on.
202 stainless steel is widely used in building decoration, municipal engineering, highway guardrail, hotel facilities, shopping malls, glass handrails, public facilities and other places. The equipment high precision automatic pipe, through its dissolve welding, roll forming, without any metal filler, filling gas protection (inside and outside of the pipe side) welding, welding process for TIG, and on-line solution of eddy current testing
202 stainless steel can not be used as food grade. According to the use of the division, food machinery or tank minimum 304, tableware is relatively low, usually with 1CR13, 2CR13,. Mainly food grade definition is the dissolution of various elements, 202 is 1Cr18Mn8Ni5N, should not meet the standards.
