2520Si2
2520Si2 stainless steel is an austenitic chromium-nickel stainless steel with good oxidation resistance and corrosion resistance. Because of the higher percentage of chromium and nickel, it It has much better creep strength and can continue to operate at high temperatures. It is a new material improved on the basis of 310S.
