Semih Metals, based in Istanbul, Turkey, is a reliable manufacturer and supplier of Stainless Steel 420 Round Bars and Rods. They pride themselves on delivering top-notch stainless steel products that are designed for strength, hardness, and resistance to corrosion. With a focus on precision and rigorous quality control, these bars and rods offer outstanding mechanical performance, accurate dimensions, and long-lasting durability. Semih Metals guarantees that their Stainless Steel 420 Round Bars and Rods meet the high standards required by industries like tooling, automotive, engineering, and aerospace, where strong, wear-resistant, and durable materials are crucial for essential applications.
The composition of Stainless Steel 420 Round Bars and Rods includes iron, chromium (12–14%), and carbon (0.15–0.40%), along with trace amounts of manganese and silicon. As a martensitic stainless steel, 420 can be hardened through heat treatment, resulting in impressive tensile and yield strength, remarkable hardness, and excellent wear resistance. This alloy also offers moderate corrosion resistance in dry and slightly corrosive environments. Its blend of mechanical strength, toughness, and corrosion resistance makes it perfect for applications that demand exceptional durability and precise performance.
