X2CrNiMo17-12-2 (EN 10272) – Solution-Annealed Steel for Pressure Vessels

Steel grade X2CrNiMo17-12-2 acc. to DIN EN 10272 : 2001-01is used for hot and cold formed rods for pressure vessels. It is a modification of steel 1.440 and shows high resistance to non-oxidizing acids and chloride containing media. It is suitable for mirror finishing and very good cold formable. The corrosion properties are improved by the lowered C-content. The steel is resistant to intercrystalline corrosion also in sensitized condition.
