Based in Houston, USA, Luois Metals is a renowned producer and supplier of Alloy Steel AISI 8620 Bars/Rods. Our speciality is AISI 8620, a low-alloy steel that combines exceptional toughness, wear resistance, and case-hardening properties. We are renowned for providing premium-quality alloy steels. Our bars and rods come in a range of sizes and heat-treated conditions, and they are manufactured to meet or surpass industry standards. Luois Metals meets the demands of the automotive, aerospace, oil and gas, and manufacturing sectors in both domestic and foreign markets with a strong emphasis on quality, accuracy, and prompt delivery.
Because of their low carbon content and composition of nickel, chromium, and molybdenum, alloy steel AISI 8620 bars and rods are perfect for carburising. After heat treatment, this alloy offers a hard, wear-resistant surface along with a tough core. Tensile strength between 620 and 850 MPa and yield strength up to 540 MPa are examples of typical mechanical properties. Excellent ductility, good fatigue resistance, and moderate machinability are all provided by AISI 8620. It is appropriate for high-wear and shock-loaded applications because of its case-hardening capability, which increases surface hardness while maintaining a strong, impact-resistant core.

AISI 8620 Bars and Rods offer excellent strength, toughness, and wear resistance, making them ideal for high-stress applications.
Yes, AISI 8620 Bars and Rods can be heat treated to enhance their hardness and overall performance for demanding applications.
AISI 8620 Bars and Rods are commonly used in automotive, aerospace, and heavy machinery industries for gears, shafts, and axles.
Applications requiring a tough core and surface hardness, particularly following carburising or case hardening, frequently use alloy steel AISI 8620 bars and rods. Automotive gears, camshafts, crankshafts, fasteners, and bushings are among the common applications. They are utilised for wear-resistant parts such as tool joints and drill bits in the oil and gas sector. AISI 8620 is also used in the heavy equipment and aerospace industries for gears and mechanical parts that are subjected to cyclic loads. It is a popular option for high-volume production of robust, load-bearing components across a variety of industries due to its strength, resistance to wear, and affordability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
