Description of material
VAL4529 is a low-carbon austenitic stainless steel with higher Molybdenum, Nickel and Nitrogen contents than grade AN4. It offers a very high resistance to pitting and crevice corrosion together with a very good resistance to general corrosion and stress corrosion cracking.
Applications
VAL4529 is suitable for the fabrication of many products such as flanges, valves, bolting, pump shafts, offshore plant, heat exchangers, storage tanks, paper and pulping bleach equipment, oil & gas production, rural applications, many products used in chemical processes, sterilizing solutions, and parts working in corrosive environments where type 316 grades and AN4 do not provide a sufficient corrosion resistance. In particular, this grade, offering a very good resistance in sea water, is widely used in naval applications.
