介绍 | Sandvik 253 MA is an austenitic chromium-nickel steel alloyed with nitrogen and rare earth metals. The grade is characterized by:
Applications The high creep strength of Sandvik 253 MA, coupled with its excellent oxidation resistance and its good resistance to carburization in constantly carburizing gas, makes it a very suitable material for end uses in which 18/8 steels lack the necessary resistance to oxidation and carburization. Sandvik 253 MA is often preferred instead of stainless chromium steels which have insufficient creep strength and structural stability. Furthermore, Sandvik 253 MA can very well take the place of higher alloyed materials such as 25Cr/20Ni steels and Alloy 800H, or even Alloy 600 in certain cases.
