SUS310S 25Cr-20Ni .
The oxidation resistance of it is better than the 309S steel, and much more used it as heat-resistant steel.
High alloy stainless steel with excellent high-temperature oxidation resistance and high-temperature strength. Components and parts that require excellent thermal resistance on exhaust equipments, heat-treatment boilers, heat-exchangers, incinerators used under high-heat, high temperature environment.
