202 is the US badge number, instead of 1Cr18Ni9. Austenitic stainless steel is characterized by high temperature of phase transition, so it can be used as heat resistant steel. To make austenitic stainless steel phase change, must be heated to more than 1000℃, and at 350℃, there will be no change in the metallography, that is to say, the performance of the steel does not change fundamentally. Will only be due to heat and lead to expansion, but the change is little, under normal circumstances can be ignored, so 202 stainless steel has good high temperature resistance. It is its performance, 202 stainless steel is widely used in architectural decoration, municipal engineering, highway guardrail, hotel facilities, shopping malls, glass handrails, public facilities and other places.
