Garg Steels, a well-respected manufacturer and supplier located in Chennai, India, specializes in high-quality Stainless Steel 420 Hex Bars. These bars are perfect for applications that require exceptional strength, wear resistance, and a polished finish. Stainless Steel 420 is a martensitic grade known for its impressive hardness after heat treatment and decent corrosion resistance. At Garg Steels, each hex bar is crafted with precision, ensuring a superior surface finish while meeting international quality standards. These bars find their place in various industries, including tool-making, medical instruments, automotive, and engineering, where durability, machinability, and an attractive finish are crucial.
Stainless Steel 420 Hex Bars consist of 12–14% chromium and 0.15–0.40% carbon, along with trace amounts of manganese, silicon, and sulfur. This martensitic stainless steel can be heat-treated to reach high hardness levels (up to 50–56 HRC), with tensile strength between 700–900 MPa. It provides moderate corrosion resistance in dry and mildly corrosive settings and boasts excellent polishability. While it may not be as corrosion-resistant as austenitic grades, it excels in wear-intensive applications. Its hexagonal shape enhances grip and strength in fasteners, tools, and precision-machined components.
