310S (old grade 0Cr25Ni20/new grade 06Cr25Ni20) is an austenitic chromium-nickel stainless steel with excellent oxidation and corrosion resistance, due to its higher percentage of chromium and nickel. It boasts superior creep strength, allowing it to operate continuously at high temperatures with good high-temperature resistance.
