EN 10272 Grade X2CrNiMo18-14-3 solution annealed (+AT)
EN 10272 Grade X2CrNiMo18-14-3 solution annealed (+AT) introduction
Steel grade X2CrNiMo18-14-3 acc. to DIN EN 10272 : 2001-01is used for hot and cold formed rods for pressure vessels. The material is an option of 1.4404 with sightly increased alloying contents for Cr, Ni and Mo, therefore improved corrosion properties. It is resistant to intercrystalline corrosion, also in sensitized condition.
