DIN1.4835 253MA UNS S30815 Austenitic Stainless Heat resistant Steel
The chemical composition of 253 ma is balanced, make the steel at 850 ℃ to 1100 ℃ temperature range has the most appropriate comprehensive performance, high resistance to oxidation, the oxidation of skin temperature as high as 1150 ℃;Extremely high variant variable capacity creep and creep rupture strength;In most of the gas medium has good resistance to high temperature corrosion and scale brush resistant ability;Higher yield strength and tensile strength at high temperature.Good formability and weldability, and enough to machinability.
Besides element chromium and nickel alloy, 253 ma stainless steel also contains a small amount of Rare Earth Metals, Rare Earth Metals, REM), so as to significantly improve its oxidation resistance.Nitrogen added to improve the creep properties and make this be fully austenitic steel.In spite of chromium and nickel content is relatively low, but this kind of stainless steel have many cases with high alloyed steel and nickel base alloy high temperature properties of the same.
