EN 10250-4 X6CrNiMoTi17-12-2 (Solution Annealed) – High-Performance Stainless Steel
Make X6CrNiMo17-12-2 is comparable to X6 CrNiMo 17-12-2 acc. to DIN17440 : 1985-07. The material is the stabilized by Ti variant of 1.4401. Due to the high Mo-content improved corrosion resistance particularly to non-oxidizing acids and halogenated media. Application in chemical apparatus engineering preferably for cellulose, sulfide, rubber, coloring, fatty acid, textile industry. Increased resistance to intercrystalline corosion also in sensitized condition. The material is unusable for mirror finishing. Application in construction trade due to its high corrosion resistance and strength for masonry anchorage coupler in concrete, as concrete reinforcement steel for stacks, sanitary engineering and facades. The Mo-alloyed rust-resistant steel is approved for construction parts of carrying function.
