202 stainless steel plate, 202 stainless steel is one of the 200 series stainless steel. 200 series stainless steels are low-nickel and high-manganese stainless steels with a nickel content of less than 4% and a manganese content of about 8%. In order to transform the austenitic stainless steel, it must be heated above 1000 °C, so at 350 °C, the metallographic structure will not change, that is, the properties of the steel will not change drastically. It can only expand due to heating, but the amount is small and usually negligible. Therefore, 202 stainless steel belt has good high temperature resistance.
? Applications: architectural decoration, municipal engineering, highway guardrails, hotel facilities, shopping malls, glass handrails, public facilities and other places.
? Machinability: Cutting, forming and machining with appropriate equipment.
High nitrogen CrMnN austenitic stainless steel has the characteristics of non-magnetic, corrosion resistance, etc., and has a wide range of needs in the industry. In the future, there will be great development in the following aspects:
1. High nitrogen CrMnNiN steel with high strength, high corrosion resistance and good low temperature toughness can be used for aircraft, aerospace and ships to provide excellent performance of rods, wires, forgings, plates, sheets to make containers, pipes, valves, cables, etc.
2. Wear-resistant, corrosion-resistant, high-toughness and high-nitrogen CrMnN austenitic stainless steel can provide corrosion-resistant and wear-resistant mechanical equipment and materials for mining equipment for the mining industry.
3. Non-magnetic, high-strength, corrosion-resistant and high-nitrogen CrMnMoN austenitic stainless steel, which can provide non-magnetic drill collars for oil fields and non-magnetic retaining rings for power plant generators.
4. High resistance to pitting and crevice corrosion High nitrogen CrNiMnMoN austenitic stainless steel can provide materials for seawater heat exchangers, seawater desalination equipment, and smoke and sulfur removal devices in coastal factories.
