Crafted from top-quality raw materials and utilizing cutting-edge metallurgical techniques, these bars are built to excel in tough industrial settings. SS 420 is a martensitic stainless steel celebrated for its excellent polishability, decent corrosion resistance, and impressive mechanical strength post-heat treatment. Tariku Metals guarantees precision in manufacturing, dimensional accuracy, and a superior surface finish, making their Stainless Steel 420 Rectangular Bars perfect for engineering, tooling, and mechanical applications around the globe.
Stainless Steel 420 Rectangular Bars are made up of roughly 12–14% chromium, 0.15% carbon, along with trace amounts of manganese, silicon, and phosphorus. This martensitic stainless steel is known for its outstanding hardness and moderate resistance to corrosion. With the right heat treatment, it can reach a tensile strength of 700–950 MPa, a yield strength of about 450 MPa, and hardness levels up to 500 HB. SS 420 also showcases good toughness, high wear and abrasion resistance, and stability under moderate heat. Its excellent machinability and ability to achieve a mirror-like finish make it a top choice for precision-engineered components.
