Material: 202 Surface: 2B / NO.1 Purpose: architectural decoration, hotel facilities, shopping malls, glass handrails, public facilities and other places Specifications: Complete specifications Origin: TISCO, Baosteel, Jiuquan Product Overview 202 stainless steel 200 series stainless steels one kind. A low-nickel 200 series stainless steel high-manganese steel, nickel content is generally below 4%, about 8% manganese, nickel stainless steel knots. 202 stainless steel is widely used in building decoration, municipal engineering, highway guardrail, hotel facilities, shopping malls, glass handrails, public facilities and other places. By precision automated system of equipment, pitting itself dissolved by welding, rolled forming, in the absence of any metal filler, the filled gas (outside of the tube) welded for TIG welding process, and for the vortex line solution testing.

These steel-hardening curve. 201 and 301 and 202 to 302 have similar hardening characteristics. 201,301 hardening larger. Generate the amount of martensite, each grade is different, 202,304 martensite generated very little, mainly by abnormal hardening process. 204,204L following steel hardening almost all rely on distortion. Mechanical properties and permeability CrMnN based material. These steels in the solution treatment state of hardness of about HV250, higher strength after cold rolling strengthening, Hv up to 500, but in this state, the magnetic permeability was still less than 1.005. [Product use 202 stainless steel is widely used in building decoration, municipal engineering, highway guardrail, hotel facilities, shopping malls, glass handrails, public facilities and other places.
