Chuck Metals is a well-respected manufacturer and supplier of Alloy Steel AISI 4130 Bars and Rods based in Singapore, catering to industries throughout Pulau Ujong and the broader Southeast Asian market. AISI 4130 is a chromium-molybdenum low-alloy steel celebrated for its impressive strength-to-weight ratio, toughness, and ease of welding. It’s a go-to choice for high-stress structural and mechanical applications. Chuck Metals provides meticulously engineered 4130 bars and rods that comply with international standards like ASTM A29/A322, ensuring they deliver dimensional accuracy, reliability, and mechanical integrity even in the toughest operational settings.
Typically, AISI 4130 Bars and Rods contain 0.28–0.33% carbon, 0.8–1.1% chromium, and 0.15–0.25% molybdenum, all of which boost hardenability and strength. This alloy boasts a tensile strength ranging from 560 to 670 MPa and a yield strength of about 460 MPa, along with excellent impact resistance. It can be heat-treated, which allows for further enhancement of its mechanical properties through quenching and tempering. Plus, 4130 is known for its good machinability and weldability, making it a top choice for components that are fabricated or machined under tough conditions.
