JIS G4304 / G4312 SUS 316L Stainless Steel Composition & Low‑Carbon Corrosion‑Resistant Properties
SUS 316L is the low‑carbon variant of SUS 316 stainless steel defined in JIS G4304 / G4312. With reduced carbon content, it minimizes sensitization during welding and enhances corrosion resistance in welded zones.
316L performs reliably in seawater, chemical media, food‑grade environments, and mildly acidic conditions. It is widely used in pressure vessels, storage tanks, hygienic systems, heat exchangers, and marine engineering components. SUS 316L is supplied as sheets, plates, strips, tubes, and bars. As a weld‑optimized version of 316, it provides superior reliability in welded structures.
