PRODUCT INTRODUCTION
S30815 253MA is a heat-resistant austenitic stainless steel, which is designed for applications requiring high creep strength and good corrosion resistance. In many cases, it has the same high-temperature characteristics as high alloying alloy steel and nickel base alloy. Due to its chemical composition balance, the steel has the most suitable comprehensive properties and high oxidation resistance in the temperature range of 850 ℃ - 1100 ℃, The peeling temperature is up to 1150 ℃; High creep resistance and creep breaking strength.
