Alloy 31 is an iron-nickel-chromium-molybdenum alloy with nitrogen addition. It has a pitting resistance in high chloride environments between those of super-austenitic stainless steels and nickel alloys. The alloy has very good corrosion resistance in mixed acid and high chloride environments. The material is approved in ISO 15156/ NACE MR0175 to test level VI for sour gas service. We can produce Alloy 31 stainless steel round rods, Alloy 31 forging, sheet, coil, and profiledstrip, Deformed steel, flat steel, mould, steel wire, have all specifications. With Bozhong Group production experience, strict control Alloy 31 chemical composition and Alloy 31 mechanical properties. From casting, forging, steel to hot and cold rolling process, heat treatment, etc, we have the control of professional engineers. We have advanced precision machining equipment, according to the requirements of users machining. in order to achieve the most satisfied with the user requirements. Production specification Round bar steel: 1mm to 3500mm Square-shape steel: 1mm to 4000mm Plate steel:0.1mm to 4000mm Width: 10mm to 2500mm Lenth: We can supply any lenth based on the customer's requirement.
