The martensitic stainless steel 420 round bar is made up of trace quantities of nickel, silicon, manganese, phosphorus, sulfur, and 12–14% chromium. The high carbon content provides superior hardness (up to 50 HRC when heat-treated), excellent strength, and moderate corrosion resistance. It has a tensile strength of 700-850 MPa, with a yield strength of 500 MPa and an elongation of 20%. It is the same as UNS S42000, DIN 1.4021, JIS SUS 420, and X20Cr13. This combination makes it an alternative to tool steels for uses that need moderate corrosion resistance and high durability.

We manufacture and supply ASME SA276 420 SS bars in various dimensions, with diameters ranging from 4 mm to 500 mm and lengths up to 6 meters or custom sizes. Our Stainless Steel 420 Square Bar is ideal for structural use, and the UNS S42000 hollow bar is preferred for its toughness and precision in machining. These bars are suitable for heavy-duty applications and industrial machinery, meeting international quality standards.

Piyush Steel guarantees prompt delivery, competitive pricing, and premium materials in both local and international markets. Get the best ASTM A276 AISI 420 stainless round steel bars for your application by getting in touch with us right now!
