Stainless steel grade 420J2 is an affordable and corrosion-resistant steel suitable for domestic, industrial, and mild atmospheric conditions. It is resistant to dilute acids, detergents, petroleum products, and steam. Though not as strong as 440 grades, it offers good strength and moderate impact resistance when hardened and tempered. Its balance of cost, corrosion resistance, and mechanical properties makes it ideal for applications like cutlery, surgical tools, and machinery parts that require moderate durability and corrosion resistance.
