George Metals, located in Houston, USA, stands out as a top manufacturer and supplier of Stainless Steel 420 Round Bars and Rods. They pride themselves on delivering high-quality, precision-engineered products that are perfect for applications needing exceptional hardness and moderate corrosion resistance. Stainless Steel 420 is a martensitic grade celebrated for its impressive polishability, strength, and wear resistance after heat treatment. Adhering to ASTM A276 and other international standards, George Metals offers bars and rods in various diameters and lengths, serving industries like automotive, tooling, medical devices, and machinery components. The company guarantees dimensional accuracy, consistent mechanical properties, and timely delivery both domestically and internationally.
Stainless Steel 420 Round Bars and Rods generally consist of 12–14% chromium and 0.15–0.40% carbon, along with trace amounts of manganese, silicon, and sulfur. This martensitic stainless steel boasts high hardness (up to 50 HRC when fully hardened), good tensile strength (~700–1000 MPa), and decent corrosion resistance in mild environments. It offers excellent machinability in its annealed state and becomes highly wear-resistant after heat treatment. George Metals ensures that their 420 bars and rods meet stringent quality standards, providing optimal performance for demanding engineering applications that require high load and wear resistance.
