Rupal Metals stands out as a reliable manufacturer and supplier of Stainless Steel 420 Hex Bars right in the heart of Delhi, India. They specialize in high-strength stainless steel products designed for applications that demand exceptional hardness and wear resistance. Stainless Steel 420 is a hardenable martensitic stainless steel celebrated for its impressive polishability, high tensile strength, and decent corrosion resistance in mild environments. Rupal Metals offers SS 420 hex bars in a variety of sizes and conditions to cater to a wide range of industrial needs. These hexagonal bars are perfect for crafting parts that require durability, precise machining, and a polished finish, such as surgical tools, fasteners, and mechanical shafts.
Stainless Steel 420 Hex Bars typically consist of Chromium (12–14%) along with a higher Carbon content (0.15–0.40%), which boosts hardenability. They also contain trace amounts of Manganese, Silicon, and Sulfur. This alloy can be heat-treated to reach a tensile strength of 700–1000 MPa and hardness levels up to 50 HRC, making it one of the toughest stainless steels out there. SS 420 is magnetic and provides moderate corrosion resistance in dry or mildly corrosive settings. It retains good edge retention and mechanical integrity under stress, making it ideal for wear-prone, precision-engineered applications.

The Hex Bar shape offers improved grip, stability, and easier alignment during machining or fabrication. It reduces rotation and slippage, allowing for more accurate cuts and efficient handling, especially when working with the hard, durable SS 420 stainless steel.
SS 420 Hex Bars are commonly used in applications requiring high wear resistance, such as shafts, valves, and tools. Its ability to be heat-treated for superior hardness and strength makes it ideal for demanding environments compared to other stainless steel grades.
Stainless Steel 420 Hex Bars find their place in various industries where hardness, edge retention, and polishability are paramount. You’ll often see them in surgical instruments, cutlery, dies, shafts, scissors, valves, and machine parts. The hexagonal shape enhances grip and torque in assemblies, making them a go-to for manufacturing mechanical fasteners and tools. SS 420 is commonly used in food processing, petrochemical, and automotive sectors where moderate corrosion resistance and high wear resistance are crucial. Plus, its ability to achieve a fine polish makes it a great choice for decorative hardware and precision components that require both strength and aesthetic appeal.
