JIS G4305 SUS316L Steel Plate | 316L Stainless Steel
General Description
As a professional stainless steel supplier and China Mill-Direct Exporter, SHH STEEL is pleased to present JIS G4305 SUS316L Steel Plate, also widely known as 316L stainless steel.
JIS G4305 SUS316L is the low-carbon version of SUS316 under the Japanese standard for cold-rolled stainless steel plates, sheets and strips. With a maximum carbon content of 0.030% and the addition of molybdenum (2–3%), SUS316L stainless steel provides excellent resistance to pitting and crevice corrosion in chloride environments, combined with superior weldability and resistance to intergranular corrosion. This makes JIS G4305 SUS316L the preferred choice for welded structures in chemical, marine, pharmaceutical and food processing industries. SHH STEEL supplies high-quality SUS316L as Mill Direct Supply from leading Chinese stainless steel mills.
