202 stainless steel is one of the 200 series of stainless steel, gb model is 1Cr18Mn8Ni5N. 202 stainless steel is widely used in building decoration, municipal engineering, highway guardrail, hotel facilities, shopping malls, glass handrails, public facilities and other places.
It is made by high-precision automatic pipe making equipment through self-dissolution welding, roll-forming, and welding by filling gas protection (inside and outside of the pipe) without any metal filler. The welding method is TIG technology, and the online solution eddy current flaw detection is performed.
202 stainless steel is one of the 200 series of stainless steel, gb model is 1Cr18Mn8Ni5N. 200 series stainless steel belongs to low nickel high manganese stainless steel, nickel content, manganese content of about 8%, is a section of nickel stainless steel.
