S31603 belongs to the American Standard austenitic stainless steel, the implementation of the standard: ASTM A276-2017
S31603 stainless steel is commonly used in the pulp and paper equipment heat exchangers, dyeing equipment, film processing equipment, pipelines, coastal areas, materials for the exterior of the building, as well as the bracelet of high-grade watches, watch cases and so on. Seawater with equipment, chemical, dye, paper, oxalic acid, fertilizer and other production equipment; photo, food industry, coastal area facilities, ropes, CD rods, bolts, nuts .S31603 is a molybdenum stainless steel species, due to the molybdenum content of the steel, the total performance of the steel is better than the 310 and 304 stainless steel, high-temperature conditions, when the concentration of sulfuric acid is less than 15% or higher than 85%, 316L stainless steel has a Wide range of uses. 316L stainless steel also has good resistance to chloride attack, so it is often used in marine environments. S31603 stainless steel has a maximum carbon content of 0.03, which can be used in applications where annealing after welding is not possible and maximum corrosion resistance is required.
The chemical composition of S31603 is shown in the following chart:
