Main components:



  20Cr-18Ni-6Mo-0.8Cu-0.2N



Product description:



254SMO is a high-chromium high resistance to erosion of the high molybdenum super-austenitic stainless steel special for environments containing halide and research and development. Because of its high molybdenum content, it has a high resistance to corrosion and crevice corrosion point function, can be used as high temperature, water and other harsh environmental conditions. Some cases can be comparable to Hastelloy and titanium, with a high resistance to corrosion of stainless steel high-economical.



254SMO co-existence of acidic medium for a variety of industrial applications. Because of the lower carbon content, it also has excellent resistance to intergranular corrosion ability.



Especially in the acid-containing halide, 254SMO is better than stainless steel. Can be used for media containing high concentrations of chloride ion the occasion, the chloride ion-induced stress corrosion, pitting corrosion and crevice corrosion resistance with excellent function.



    Typical Application



Water treatment plant, plate heat exchangers, paper industry equipment, bellows compensator, desulphurization and denitrification plants, drugs and other chemical reaction vessel equipment.



       The relevant scale



NAS 185N, UNS S31254, DIN / EN 1.4547, ASTM A240, ASME SA-240
