These bars are celebrated for their impressive strength, hardness, and decent corrosion resistance. Crafted with precision and in line with international standards, they’re perfect for industries that need durable materials with great machinability and polishability. The Stainless Steel 420 Flat Bar from Isis Metals is engineered to provide outstanding wear resistance and performance, even in high-stress situations. With remarkable dimensional accuracy and finish, these bars find their place in engineering, mechanical, and industrial applications that demand reliability and toughness.
Stainless Steel 420 Flat Bar is a martensitic stainless steel primarily made up of chromium (12–14%) and carbon (0.15–0.40%), along with trace amounts of manganese, silicon, and nickel. This unique blend gives the alloy a great balance of strength, hardness, and corrosion resistance. When heat-treated, it can reach a tensile strength of 700–950 MPa and boasts excellent wear resistance. The alloy is also known for its good polishability, machinability, and dimensional stability. SS 420 remains durable and offers moderate corrosion resistance in mildly acidic or moist environments, making it a solid choice for heavy-duty applications.
