Austenitic heat-resistant stainless steel 310S (0Cr25N i20) is a high-chromium-nickel austenitic stainless steel. 310S stainless steel exhibits excellent oxidation and corrosion resistance. Its high percentages of chromium and nickel contribute to its significantly improved creep strength, enabling sustained operation at high temperatures and excellent high-temperature resistance. Due to its high nickel (Ni) and chromium (Cr) content, 310S heat-resistant steel exhibits excellent resistance to oxidation, corrosion, acid and alkali, and high temperatures. As a key material in the aerospace and chemical industries, it is widely used in high-temperature environments.
