Product Details

202 Stainless Steel Strip,1CR18MN8NI5N is 202, tensile strength 520MPa, section shrinkage rate 45%, and 0cr18ni9 is 304, tensile strength 520MPa, section shrinkage rate 60%, you can see 202 Stainless Steel Strip contains a higher C, hardness is slightly higher, but the ductility of less than 304, But the strength difference is not very.

202 is the United States sign number, instead of 1cr18ni9. Austenitic stainless steel is characterized by a high phase change temperature, so can be used as heat-resisting steel. To make austenitic stainless steel phase change, must be heated to 1000 ℃ above, so in 350 ℃, will not occur metallographic changes, that is, the performance of steel does not occur drastically. Only because of the expansion of heat, but the amount is very small, in general, can be ignored, for this 202 stainless steel strip has a good high temperature resistance.
