JIS G4304 SUS310S stainless steel plate equivalent Grades
If you're sourcing SUS310S stainless steel plates for heat-resistant or corrosive environments, it's essential to understand its international equivalents to ensure material compatibility and compliance. Defined under JIS G4304, SUS310S is a high-alloy austenitic stainless steel plate widely used in furnace components, heat exchangers, and petrochemical equipment.
This article helps you identify equivalent standards, compare chemical composition and mechanical properties, and make informed procurement decisions.
What is SUS310S Stainless Steel sheets ?
SUS310S rolled stainless steel sheet is a low-carbon version of SUS310, designed to resist oxidation, high temperatures (up to 1150°C), and cyclic thermal stress. The lower carbon content improves its weldability and reduces the risk of carbide precipitation.
