0Cr17Ni12Mo2 Stainless Steel Composition & Molybdenum‑Alloyed Corrosion Resistance

0Cr17Ni12Mo2 is a molybdenum‑alloyed austenitic stainless steel specified in GB/T 4237 and GB/T 4238, equivalent to Grade 316. Containing approximately 17% chromium, 12% nickel, and 2% molybdenum, it provides enhanced resistance to pitting and crevice corrosion in chloride‑containing environments.

The grade is commonly used in marine applications, chemical equipment, food‑processing machinery, pressure vessels, and heat‑exchange systems. Compared with standard 304 stainless steel, it delivers superior durability in seawater, salt‑spray, and corrosive media.

0Cr17Ni12Mo2 is supplied as sheets, strips, plates, tubes, and bars for marine engineering, chemical processing, and pharmaceutical applications.
