Chuck Metals stands out as a top manufacturer and supplier of Alloy Steel AISI 8630 Bars and Rods right here in Singapore, Pulau Ujong. They’re all about delivering high-performance materials tailored for the oil & gas, automotive, aerospace, and heavy engineering sectors. AISI 8630 is a low-alloy steel that’s celebrated for its remarkable toughness, hardenability, and strength after heat treatment. Chuck Metals offers these bars and rods in a variety of sizes, conditions (like annealed, normalized, and quenched & tempered), and finishes to cater to the specific needs of different industries. With a strong focus on quality, precision, and speedy delivery, Chuck Metals guarantees reliable performance for critical applications.
When it comes to composition, Alloy Steel AISI 8630 Bars and Rods typically contain around 0.28–0.33% carbon, 0.40–0.60% manganese, 0.80–1.10% nickel, 0.40–0.60% chromium, and 0.15–0.25% molybdenum. This blend gives the steel its impressive hardenability, strength, and ductility. After heat treatment, it achieves tensile strengths ranging from 700–900 MPa, along with outstanding toughness and impact resistance. Plus, it boasts good weldability and machinability when in the normalized or tempered state, and can be case hardened for enhanced wear resistance while maintaining a strong, ductile core.
