410 Stainless Steel Strip is a high-strength, martensitic stainless steel known for its excellent wear resistance and corrosion resistance. With a composition that includes 11.5-13.5% chromium, this alloy provides a good balance of corrosion resistance and mechanical properties, making it ideal for applications requiring high strength and moderate corrosion resistance. 410 stainless steel can be heat treated to achieve a wide range of mechanical properties, making it a versatile material for various industrial uses.
General Characteristics
- Composition: 410 stainless steel is a martensitic stainless steel grade with a minimum chromium content of 11.5%. It also contains trace amounts of elements such as Ti, Mo, and Nb.
- Magnetic Properties: It is magnetic in both annealed and hardened conditions.
- Corrosion Resistance: It offers good corrosion resistance in moderate environments, tolerating weak acids, alkalis, steam, food, and freshwater. However, its corrosion resistance is lower than austenitic grades and 430 ferritic alloy with 17% chromium.
- Strength and Hardness: 410 stainless steel exhibits high strength and hardness, with a tensile strength of 60 KSI and a yield strength of 30 KSI.
Processing and Heat Treatment
- Annealing: It can be fully annealed at temperatures ranging from 815 to 900 °C, followed by slow furnace cooling or air cooling. Process annealing is performed at 650 to 760 °C with air cooling.
- Hardening: Hardening can be achieved by heating to 925 to 1010 °C and then quenching in air or oil. Heavier sections require oil quenching.
- Tempering: To improve mechanical properties and hardness, tempering is recommended, though not advisable between 400 and 580 °C.
