Chung Metal Manufacturer & Suppliers in Da Nang, Vietnam, provides high-quality Alloy Steel AISI 8630 bars and rods to demanding industries that need high strength, toughness, and hardenability. Through exact chemistry control and rigorous heat treatments, our 8630 bars arrive with traceability and repeatable quality. We have expertise in custom diameters, lengths, and surface finish conditions to suit stringent requirements. Our quality systems and facilities guarantee that every rod conforms to mechanical specifications and metallurgical integrity. Customers in tooling, aerospace, automotive, and energy industries depend on our 8630 alloy to manufacture long‑lasting, wear‑resistant components for heavy-duty use.
AISI 8630 is a nickel‑chromium‑molybdenum low‑alloy steel containing about 0.30% C, 1.25% Cr, 0.30% Mo, 0.40% Ni, and traces of Mn, Si, S, P. It can undergo through‑hardening and carburizing. In quenched and tempered state, tensile strength up to 850–1,100 MPa, yield strength ~700–900 MPa, with elongation ~12–20%. Hardness can go up to ~280–350 HB (or higher based on heat treatment). It offers superior toughness, fatigue life, and machinability. The alloy is highly responsive to carburizing, nitriding, and surface treatments.
