1CR18MN8NI5N is 202, tensile strength 520MPa, section shrinkage 45%. It can be seen that 202 contains a higher amount of C, the hardness is slightly higher.
202 stainless steel coil is widely used in building decoration, municipal engineering, Highway guardrail, hotel facilities, shopping malls, glass handrails, public facilities and other places.
202 is the United States signage number, in place of 1cr18ni9. Austenitic stainless steel is characterized by a high phase change temperature, so it can be used as a heat-resistant steel.In order to make austenitic stainless steel phase change, it must be heated to more than 1000 ℃, so in 350 ℃, there will be no change in metallographic structure, that is, the performance of steel does not change dramatically.will only be inflated by heat, but the amount is very small, generally negligible, for this 202 stainless steel belt has a good high temperature resistance.
In the future, there will be greater development in the following areas:
Stainless Steel knowledge：
Stainless steel refers to the resistance to air, steam, water and other weak corrosive media and acid, alkali, salt and other chemical etching media corrosion of steel, also known as rust-resistant steel. In practical applications, steel that is resistant to weak corrosive media is often referred to as stainless steel, while steel corrosion resistant to chemical media is called acid-resistant steel.Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter is generally non-rust.The corrosion resistance of stainless steel depends on the alloy elements contained in the steel.
