Heat resistance refers to the high temperature stainless steel can still maintain its excellent physical and mechanical properties.
Carbon effect: carbon is strongly formed and stable in austenitic stainless steel. Element of definite austenite and enlarged austenite region. Carbon is about 30 times more capable of forming austenite than nickel. Carbon is a gap element, and the strength of austenitic stainless steel can be significantly improved by solid solution strengthening. Carbon also improves the stress and corrosion resistance of austenitic stainless steel in highly concentrated chlorides such as 42%MgCl2 boiling solution.
