Desta Steel, a leading manufacturer and supplier based in Addis Ababa, Ethiopia, has built a solid reputation for its top-notch stainless steel products that adhere to international quality standards. Among their standout offerings, the Stainless Steel 420 Round Bars and Rods are particularly celebrated for their impressive hardness, strength, and resistance to corrosion. Crafted with cutting-edge technology and meticulous engineering, these bars and rods are perfect for applications that demand durability and wear resistance. Desta Steel is committed to ensuring that each product goes through rigorous quality control, providing dependable and consistent materials for industrial, mechanical, and structural applications both in Ethiopia and beyond.
Stainless Steel 420 Round Bars and Rods are a type of martensitic stainless steel, mainly made up of iron, with 12–14% chromium and a controlled carbon content of up to 0.40%. This specific mix gives it impressive hardenability when heat-treated. When hardened, this alloy boasts a tensile strength of about 700 MPa and a yield strength of around 450 MPa, which translates to excellent wear resistance and decent corrosion resistance. It also has good polishability and machinability, making it a great choice for precision components. However, keep in mind that its toughness can drop at low temperatures, and you might need to anneal it to regain ductility after working with it.
