06Cr17Ni12Mo2Ti Stainless Steel Introduction
06Cr17Ni12Mo2Ti (old designation 0Cr18Ni12Mo2Ti) is a titanium-stabilized austenitic stainless steel defined in GB/T 4237 for hot-rolled plates and coils. The addition of molybdenum enhances pitting and crevice corrosion resistance in chloride environments, while titanium stabilization prevents intergranular corrosion after welding or high-temperature service. This alloy offers good high-temperature strength and deep drawing characteristics, and is widely used in chemical processing, petrochemical, and marine applications. It is generally supplied in solution-annealed condition with a microstructure free of deleterious chromium carbides.

06Cr17Ni12Mo2Ti Stainless Steel Application Introduction
06Cr17Ni12Mo2Ti is selected for applications requiring outstanding resistance to intergranular corrosion after welding in combination with molybdenum-enhanced pitting resistance. It is particularly suited for chloride-containing environments and moderate high-temperature service (up to ~800 °C). The alloy is easily formed, bent, and deep drawn, and can be welded by all common methods using matching filler metals.
Product Applications: Hot-rolled plates for pressure vessels and storage tanks, Coils for welded pipe and tube production, Cut and machined parts for chemical reactors, Baffle plates and tube sheets for heat exchangers, Lining sheets for corrosion protection, Structural sections in aggressive atmospheres

Application industries: Chemical and petrochemical processing, Heat exchanger and condenser manufacturing, Flue gas desulfurization (FGD) systems, Marine and offshore engineering, Pharmaceutical and food processing equipment, Pulp and paper industry, Pressure vessel and boiler construction, Nuclear (secondary circuit components, with appropriate qualification)
06Cr17Ni12Mo2Ti Stainless Steel Similar / Substitute Materials with Comparable Performance
| Country/Region | Standard | Grade | Remarks |
|---|---|---|---|
| China | GB/T 4237 | 06Cr17Ni12Mo2 (316L) | Low carbon variant without Ti; slightly lower intergranular corrosion resistance in thick sections but better weldability without stabilization |
| China | GB/T 4237 | 06Cr17Ni12Mo2Ti-NS | Nitrogen-strengthened version; higher strength, similar corrosion resistance |
| European Union | EN 10088-2 | X2CrNiMo17-12-2 (1.4404) | 316L; suitable for many similar applications if full carbide stabilization is not required |
| USA | ASTM A240 | 316L (UNS S31603) | Widely used substitute, especially for lighter gauge and non-welded components |
| Japan | JIS G4304 | SUS316L | Equivalent to EN 1.4404; similar corrosion resistance but without titanium stabilization |
| European Union | EN 10088-2 | X6CrNiMoTi17-12-2 (1.4571) | Identical to 06Cr17Ni12Mo2Ti; often directly interchangeable |
Notes:
Intergranular corrosion resistance is assured through Ti stabilization if the material is properly solution annealed and not exposed to excessively long sensitization times (the time-temperature-precipitation characteristics are improved compared to unstabilized 316). Welding: When using matching filler metal (e.g., E316LT1-1 or ER316LT1), Ti loss is minimal; post-weld heat treatment is usually not required for general service. Machining: The work-hardening rate is lower than that of 304 types, but sharp tools and proper lubrication are recommended. For some specifications, a titanium content of 5×(C+N) is adopted; verify actual standard edition. Surface finish: Plates and coils can be supplied in No.1, 2D, 2B, or other finishes per agreement.
