What material is 316L stainless steel? What is the performance?

316L is molybdenum containing stainless steel with the maximum carbon content of 0.03%. Due to the addition of 2% ~ 3% Mo in the steel, 316L stainless steel has the following excellent properties: corrosion resistance, especially pitting corrosion resistance, under high temperature conditions, when the concentration of sulfuric acid is lower than 15% or higher than 85%, it has a wide range of uses, marine and corrosive industrial atmospheric corrosion resistance, and its corrosion resistance is better than 304 stainless steel.

316L stainless steel has high temperature resistance and good creep resistance. It can be used intermittently below 1600 ℃ and continuously below 700 ℃. It can be used in the range of 800 ~ 15759 ℃. It is better not to use it continuously. However, 316L stainless steel has good heat resistance when it can be used continuously outside this temperature range; it also has good resistance to chloride corrosion, so it is usually used in marine environment, and its carbide precipitation resistance is better than that of 316 stainless steel.

316L stainless steel has good oxidation resistance, work hardening (weak magnetic after processing), non-magnetic in solution state, and good appearance gloss of cold-rolled products. The overall performance is better than 310 and 304 stainless steel, but the price is higher than 304 stainless steel. It can be used in applications where annealing is not possible after welding and where maximum corrosion resistance is required. It has good corrosion resistance in the production process of pulp and paper, and is generally used in the annealed solid solution state.

316L stainless steel is mainly used for heat exchanger and dyeing equipment of pulp and paper equipment; film processing equipment; pipeline; watch chain and case of high-grade watch; production equipment of oxalic acid and fertilizer in chemical industry; equipment for photography, food industry and seawater; materials for facilities and buildings in coastal areas; ropes, CD rods, bolts, nuts, etc. Corresponding steel material: 022cr17ni12mo2.
