0Cr18Ni12Mo2Ti Stainless Steel Composition & Titanium‑Stabilized Corrosion Resistance

0Cr18Ni12Mo2Ti is a titanium‑stabilized molybdenum‑alloyed austenitic stainless steel specified in GB/T 4237 and GB/T 4238, comparable to 316Ti‑type grades. It contains approximately 18% chromium, 12% nickel, 2% molybdenum, and titanium for improved resistance to carbide precipitation during welding and elevated‑temperature service.

The grade combines excellent corrosion resistance, weldability, and thermal stability. It is commonly used in heat exchangers, pressure vessels, chemical processing equipment, boiler components, and high‑temperature piping systems.

0Cr18Ni12Mo2Ti is available as sheets, coils, tubes, bars, and plates. It is widely applied in petrochemical plants, power equipment, thermal processing systems, and industrial engineering projects.
