Chuck Metals stands out as a reliable manufacturer and supplier of top-notch Stainless Steel 420 Rectangular Bars in Singapore, specifically in Pulau Ujong. Known for their precision-engineered stainless steel products, Chuck Metals serves a variety of industries, including tooling, medical, automotive, and engineering. Stainless Steel 420 is a martensitic type that boasts high hardness, impressive wear resistance, and decent corrosion resistance. Chuck Metals ensures that their 420 rectangular bars come with tight dimensional tolerances, a superior surface finish, and consistent quality. These bars are perfect for applications that require strength, polishability, and durability, especially in moderately corrosive and high-friction environments.
Stainless Steel 420 (UNS S42000) generally contains 12–14% Chromium and 0.15–0.40% Carbon, along with small amounts of Manganese, Silicon, Phosphorus, and Sulfur. This hardenable martensitic steel can achieve a hardness of up to 50 HRC when heat-treated. With a tensile strength ranging from 655–860 MPa, it also offers good impact resistance. Being magnetic, it shows moderate corrosion resistance in air, water, and food-grade settings. The rectangular shape ensures uniformity and versatility in fabrication, machining, and mechanical assemblies, making it suitable for both structural and precision applications.
