Application and characteristics of S31603 stainless steel material

　　S31603 stainless steel material

　　S31603 stainless steel is an American standard austenitic stainless steel with a maximum carbon content of 0.03, which can be used in applications where annealing after welding is not possible and where maximum corrosion resistance is required.

　　S31603 stainless steel is a molybdenum-containing stainless steel. Because of the molybdenum in the steel, the overall performance of this steel is better than 310 and 304 stainless steel. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% or higher than 85%, 316L stainless steel has a wide range of properties. the use of. 316L stainless steel also has good resistance to chloride attack, so it is usually used in marine environments.

　　S31603 stainless steel application

　　S31603 stainless steel is commonly used in pulp and paper equipment heat exchangers, dyeing equipment, film processing equipment, pipelines, external materials for buildings in coastal areas, and watch chains and cases for high-end watches. Equipment used in seawater, chemical, dye, papermaking, oxalic acid, fertilizer and other production equipment; photography, food industry, coastal area facilities, ropes, CD rods, bolts, nuts.

　　S31603 stainless steel characteristics

　　1. Corrosion resistance

　　S31603 stainless steel has a similar ability to resist general corrosion as the unstable nickel-chromium alloy 304, and prolonged heating in the temperature range of chromium carbide may affect the performance of alloys 321 and 347 in harsh corrosive media. It is mainly used in high temperature applications, which require the material to have strong anti-sensitization properties to avoid intergranular corrosion at lower temperatures.

　　2. High temperature oxidation resistance

　　All s31603 stainless steels have high temperature oxidation resistance, but the oxidation rate will be affected by inherent factors such as exposure environment and product shape.

　　3. Physical properties

　　The total heat transfer coefficient of metal depends not only on the thermal conductivity of the metal, but also on other factors. In most cases, the heat dissipation coefficient of the film layer, the rust and the surface condition of the metal, stainless steel can keep the surface clean, so its Conducts heat better than other metals with higher thermal conductivity.
