Norman Nickel Alloys is your go-to manufacturer and supplier of top-notch Alloy Steel AISI 8620 Bars right here in Kuala Lumpur, Malaysia. We pride ourselves on delivering precision-engineered products that are built for outstanding performance. AISI 8620 is well-known for its remarkable toughness, wear resistance, and core strength, making it a popular choice in tough industrial settings. Our bars are crafted using cutting-edge manufacturing techniques and rigorous quality control to ensure they meet international standards. We cater to a variety of industries, including automotive, aerospace, oil and gas, and engineering, providing AISI 8620 Bars that guarantee reliability, machinability, and a long service life in critical applications.
Alloy Steel AISI 8620 Bars are low-alloy, case-hardening steels that typically contain around 0.18–0.23% carbon, 0.40–0.70% manganese, 0.40–0.60% nickel, 0.40–0.60% chromium, and 0.15–0.25% molybdenum. This unique blend gives them a tough core with excellent hardenability and a wear-resistant surface after carburizing. You can expect mechanical properties like a tensile strength ranging from 620–850 MPa, good ductility, and high impact resistance, making them perfect for components that need both surface hardness and core toughness.
