Harshita Stainless is a reputable manufacturer and supplier based in Delhi, India, specializing in a diverse array of high-performance stainless steel products, including Stainless Steel 420 Pipes. These pipes are celebrated for their impressive strength, hardness, and moderate resistance to corrosion, making them perfect for situations where durability and wear resistance are crucial. Crafted from top-quality materials using cutting-edge production techniques, our SS 420 Pipes adhere to strict national and international standards. At Harshita Stainless, we are committed to providing top-notch stainless steel piping solutions, ensuring precise dimensions, timely deliveries, and outstanding customer support for clients both in India and around the world.
Stainless Steel 420 Pipes are constructed from a martensitic stainless steel alloy that contains about 12–14% chromium and up to 0.15% carbon. This unique composition allows the material to be heat-treated, resulting in exceptional hardness and tensile strength—reaching up to 700 MPa or even more. SS 420 boasts good wear resistance and fair corrosion resistance in mild environments, and it remains magnetic whether in its annealed or hardened state. It also shows moderate ductility and impact strength. While it may not match the corrosion resistance of austenitic grades, SS 420 excels in applications that demand strength and resistance to abrasion or mechanical wear.
