Product Overview

UNS S30815 and 253MA are the same material. As an austenitic heat-resistant stainless steel, it uses Cr, Si, N and Ce synergy (instead of high nickel, only 10.0-12.0% Ni) for superior high-temperature performance, more cost-effective than 310S.

It is suitable for 500-1150ºC high-temperature equipment in oxidation, carburization and sulfur-containing atmospheres, widely used in energy, petrochemical, metallurgical and environmental protection industries.
