ASTM A240 316 Stainless Steel Composition & Corrosion‑Resistant Properties
ASTM A240 316 (UNS S31600) is a molybdenum‑alloyed austenitic stainless steel grade under ASTM standards. With 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, it offers significantly improved resistance to pitting and crevice corrosion in chloride‑rich environments compared with the 304 family.
316 is widely used in seawater systems, chemical processing equipment, food‑processing machinery, pressure vessels, heat exchangers, and pump and valve components. It maintains excellent weldability and retains corrosion resistance after welding.
316 is supplied as sheets, plates, strips, tubes, and bars. As a molybdenum‑alloyed stainless steel, it provides dependable performance in aggressive industrial environments, especially where chloride exposure is present.
