J4AUSTENITIC STAINLESS STEELGeneral Characteristics:J4 Grade is a chromium-manganese austenitic stainless steel with moderate amounts of copper,nickel and nitrogen. Balancing of the alloying elements produces an austenitic structure in theannealed condition.Type J4 is suitable for replacing chromium-nickel grades 301, 304 in many applications. Lowercost manganese and nitrogen additions render this grade more economical while endowing it withgood strength and high formability making it highly suitable for a wide variety of consumer andstructural applications. Presence of copper in this steel reduces work hardening rate. The alloy isnon-magnetic in annealed condition and like 304 becomes lightly magnetic after cold working dueto formation of martensite. Thus J4 can display a wide range of mechanical strength depending onthe degree of cold working, which is essential for certain structural applications.Chemical Mechanical Properties:Mechanical propertiesJ4UTS(MPa)YS(MPa)%ELHardness(HRB)650 min325 min40 min100 maxProducts available:Hot Rolled Plates & Coil, Cold Rolled Coil & SheetsApplications:Deep drawn kitchen equipment, Furniture, Bins, Coal Bucket, Wear Plate Liners andHoppers, Cookware & Serving Bowls, Window Channel Spacers etc.1
