EN 10217-7 Grade X2CrNiN23-4 solution annealed (+AT)
EN 10217-7 Grade X2CrNiN23-4 solution annealed (+AT) introduction
The austenitic ferritic steel X2CrNiN23-4 is available in the solution annealed condition. Welded circular tubes of this steel are used for compression load and for corrosive load at room temperature, low temperatures and elevated temperatures. The material is resistant to intercrystalline corrosion (up to 265 °C) also in the welded condition.
Equivalent material: GB 022Cr23Ni4MoCuN, GB S23043, UNS S32304, DIN 1.4362, DIN X2CrNiN23-4, AFNOR Z2CN23-04AZ, SS 2327, AISI S32304, SAE S32304, EN 1.4362, ASTM 2304
