EN 10028-7 Grade X2CrNiMo18-15-4 solution annealed (+AT)
EN 10028-7 Grade X2CrNiMo18-15-4 solution annealed (+AT) introduction
The austenitic steel X2CrNiMo18-15-4 shows very high resistance to unoxidizing and halogenated media due to its high Mo-content (more than 3%), furthermore resistance to intercrystalline corrosion even in sensitized condition. It is usable for mirror-polishing and is cold formable.
The steel is permitted for pressure vessel construction.
Application: in chemical apparatus engineering especially in cellulose industry, in textile and rayon industry, in tankship construction and for transport containers
