Dual-Grade 316/316L Stainless Steel Pipe
316/316L is dual-grade austenitic stainless steels widely used in corrosive and high-temperature environments. The key difference lies in carbon content: 316 (≤0.08% C) offers higher strength, while 316L (≤0.03% C) prioritizes weldability and resistance to post-weld corrosion. Both share identical chromium (16–18%), nickel (10–14%), and molybdenum (2–3%) content, with near-matching density (~8.0 g/cm³, ±1–2% variance).
