Rupal Metals stands out as a reliable manufacturer and supplier of Stainless Steel 420 Rectangular Bars right in the heart of Delhi, India. They specialize in crafting stainless steel products that are not only precise but also renowned for their remarkable hardness and resistance to corrosion. SS 420 is a martensitic stainless steel grade that boasts impressive wear resistance, a high polishability, and strength that can be enhanced through heat treatment. These rectangular bars are perfect for creating durable components in industries that require both a sleek appearance and top-notch mechanical performance. Rupal Metals offers SS 420 rectangular bars in a variety of sizes and specifications, making them ideal for use in tooling, cutlery, automotive, and industrial machinery.
Stainless Steel 420 Rectangular Bars generally consist of Chromium (12–14%) and Carbon (0.15–0.40%), along with trace amounts of Manganese, Silicon, and Sulfur. This grade can be heat-treated to achieve impressive tensile strength (700–1000 MPa) and hardness levels up to 50 HRC. SS 420 is magnetic and provides moderate corrosion resistance in less aggressive environments. It excels in applications where wear resistance and edge retention are crucial. The rectangular shape ensures excellent surface contact and structural integrity, making these bars perfect for shaping, machining, and load-bearing tasks that demand precision and durability.
