Chuck Metals stands out as a top manufacturer and supplier of Stainless Steel 420 Round Bars and Rods in Singapore, catering to a variety of industrial sectors across Pulau Ujong and Southeast Asia. This high-carbon martensitic stainless steel, known as Stainless Steel 420, is celebrated for its impressive hardness, wear resistance, and decent corrosion resistance. Our 420 round bars are crafted in line with ASTM A276 and A479 standards, guaranteeing precision, durability, and a superior surface finish. We offer 420 bars in different heat-treated conditions, making them perfect for cutting tools, surgical instruments, and any application that demands high strength and edge retention.
Typically, Stainless Steel 420 Round Bars and Rods contain 12–14% chromium and at least 0.15% carbon, with very little nickel. When hardened and tempered, they can achieve tensile strength between 700–900 MPa and yield strength around 345 MPa, along with impressive hardness (up to 50 HRC). This alloy is magnetic and can be polished to a brilliant finish. While its corrosion resistance isn’t as high as that of austenitic grades, it performs admirably in mild environments, especially when fully hardened. Its machinability and responsiveness to heat treatment make it a go-to choice for wear-resistant applications.
