Material Name: Stainless Steel

Grade: SUS310S

Standard: JIS G4311:1991

Features and Application Range:

SUS310S stainless steel is a type of austenitic stainless steel from the Japanese SUS series. It has better corrosion resistance than 0Cr23Ni13. It is actually primarily used as heat-resistant steel.
