Suppliers, Traders, Exporters and Stockists of Stainless Steel Grade 420 Round Bars & SS Rods
ARK Stainless is a leading supplier, trader, stockist, and exporter of Stainless Steel 420 Round Bars and SS 420 Rods. Our SS 420 Round Bars are crafted from martensitic stainless steel, boasting a high yield strength of up to 1365 MPa at 316 degrees Celsius and a minimum tensile strength of 1620 MPa at 427 degrees Celsius. The standard values are 495 MPa for yield and 700 MPa for tensile strength, ensuring optimal performance in demanding environments.
We pride ourselves on being top suppliers of SS 420 Round Bars and rods in various shapes, sizes, and dimensions. The composition includes carbon, manganese, silicon, phosphorus, sulfur, and 11.5% chromium, providing excellent corrosion resistance. Our product range includes different specifications, types, and finishes, such as ASTM A276 type 420 Bright Round Bars, available in finishes like bright, polished, or black.
Our Stainless Steel 420 Round Bars come in sizes ranging from 3mm to 350mm and are offered in multiple forms, including round, square, hex, rectangular, wire, ingot, forging, and wire mesh. The UNS S42000 AISI 420 Black Bar can be utilized without polishing in general corrosive applications due to its inherent corrosion resistance. Martensitic steel grades are known for their exceptional wear and tear resistance, making them ideal for various industrial applications.
The ASTM A479 Stainless Steel 420 Hex Bar is available in lengths of 1 to 6 meters, with custom cut-to-length options. Our hex bars feature thicknesses ranging from 18mm to 57mm, comparable to our Stainless Steel 420 Square Bar offerings. The SS 420 Cold Drawn Round Bar is the most popular choice within this grade, suitable for construction, shipbuilding, bridge building, and engineering applications.
SS 420 Bars are high-performance materials used in applications requiring extreme wear and heat resistance. The 420 Stainless Round Bar is frequently utilized in gas turbine engines due to its strength and resistance to high temperatures. A hardened finish enhances durability, with tempering at lower temperatures being the best method for improving polishing performance and corrosion resistance.
These versatile bars are used in various applications, including plunger rods, electrical equipment, and household appliances. They are also manufactured into components that withstand atmospheric pressure, oxidizing acids, and water. Beyond these applications, SS 420 is ideal for rollers, precision machinery, and transportation tools.
With a maximum hardness of 48 HRC, 420 stainless steel rods offer extreme durability and strength, making them perfect for industrial uses that demand long wear life. Available in multiple forms and finishes, Stainless Steel 420 Round Bars stand out as a reliable choice in harsh environments.
We are proud to export our SS 420 Round Bars and Stainless Steel 420 Rods to countries including the United Arab Emirates, Brazil, Russia, Bangladesh, Indonesia, Egypt, Qatar, Iran, Kuwait, Taiwan, Oman, South Africa, Saudi Arabia, Australia, Pakistan, and Malaysia. Trust ARK Stainless for high-quality stainless steel solutions that meet your industrial needs.
