SUS410J1 Stainless Steel | Stainless Steel Supply

SUS410J1 is a martensitic stainless steel material specified in the Japanese Industrial Standard JIS G4303. It is known for its excellent hardenability, high hardness, toughness, corrosion resistance, thermal strength, and ability to withstand cold deformation. Additionally, it has impressive shock absorption properties. Proper tempering is crucial for maximizing its properties; it should be tempered at high or low temperatures, but tempering between 370-560 ℃ should be avoided.
SUS410J1 with superior corrosion resistance compared to 410. It displays good machinability and corrosion resistance after quenching and tempering, resulting in increased strength and toughness. This steel is commonly utilized in manufacturing parts that require resistance to atmospheric, water vapor, water, and oxidative acid corrosion, such as automotive turbine blades and high-temperature components.
