Chuck Metals stands out as a trusted manufacturer and supplier of top-notch Stainless Steel 420 Hex Bars in Singapore, specifically in Pulau Ujong. With a reputation for precision machining and metallurgical excellence, Chuck Metals caters to various sectors, including tooling, medical, defense, automotive, and industrial engineering. Stainless Steel 420 is a high-carbon martensitic stainless steel celebrated for its remarkable hardness, polishability, and corrosion resistance post-heat treatment. Chuck Metals guarantees that all 420 hex bars are produced to meet international standards, backed by rigorous quality control. Their 420 hexagonal bars deliver outstanding dimensional stability and strength, making them ideal for high-stress, high-wear applications in tough environments.
Stainless Steel 420 (UNS S42000) is composed of about 12–14% Chromium and 0.15–0.40% Carbon, along with trace amounts of Manganese, Silicon, and other elements. It can be heat-treated to achieve a hardness of up to 50 HRC, depending on the carbon content and tempering process. This alloy boasts a tensile strength ranging from 655–860 MPa and offers moderate corrosion resistance when hardened. It’s magnetic and exhibits excellent wear resistance, particularly when hardened and ground. The combination of machinability, polishability, and strength makes 420 perfect for precise, load-bearing applications where both aesthetics and durability are essential.
