A high-alloy steel that can resist corrosion in the air or in chemically corrosive media. Stainless steel has a beautiful surface and good corrosion resistance. It does not need to undergo surface treatment such as color plating, but instead exerts the inherent surface properties of stainless steel. It is used in many A type of steel, commonly referred to as stainless steel. The representative performance is high alloy steel such as 13 chrome steel and 18-8 chrome nickel steel. From the metallographic point of view, because the stainless steel contains chromium, a very thin chromium film is formed on the surface, which isolates the oxygen from the steel and plays a role in corrosion resistance. In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium. 304 is a general purpose stainless steel that is widely used to make equipment and parts that require a good combination of properties (corrosion resistance and formability). 304 stainless steel is a grade of stainless steel produced according to the American ASTM standard. 304 is equivalent to my country's 06Cr19Ni10 (0Cr18Ni9) stainless steel. 304 contains 18% chromium and 8% nickel. 301 is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy, etc. 304 stainless steel chemical composition specification C Si Mn P S Cr Ni (nickel) MoSUS431 ≤0.08 ≤1.00 ≤2.00 ≤0.05 ≤0.03 18.00-20.00 8.25~10.50 -304 is 0Cr18Ni9. 301 (17Cr-7Ni-carbon) material: Compared with 304 steel, the content of Cr and Ni is less, the tensile strength and hardness are increased during cold working, and it is non-magnetic, but it is magnetic after cold working. Uses: trains, aircraft, conveyor belts, vehicles, bolts, springs, screens. Remarks: L stands for low carbon, such as 304L has lower carbon content than 304. H and S represent high temperature resistance. For example, 310S has stronger high temperature resistance than 310, and 304H is more heat resistant than 304.
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 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 pitting corrosion resistance, crevice corrosion resistance, high nitrogen CrNiMnMoN Austenitic stainless steel can provide materials for seawater heat exchangers, seawater desalination equipment, and flue gas and sulfur removal devices in coastal factories.
