AISI 8620 Round Bars are low-alloy nickel–chromium–molybdenum steel bars known for their excellent hardenability, toughness, and wear resistance. They are widely used in carburized and case-hardened applications, offering a hard, wear-resistant surface with a tough and ductile core. These round bars provide good machinability, dimensional stability, and reliable performance under cyclic loads. AISI 8620 round bars are commonly used in gears, shafts, pinions, bushings, automotive components, and general engineering applications where strength, wear resistance, and long service life are essential.

ASTM A182 F11 / F12 Round Bars are chromium–molybdenum alloy steel bars designed for high-temperature and high-pressure applications. They offer excellent strength, toughness, and resistance to oxidation and corrosion at elevated temperatures. These round bars provide good weldability, durability, and dimensional stability under severe operating conditions. ASTM A182 F11 / F12 round bars are widely used in pressure vessels, boilers, heat exchangers, petrochemical and power plants, and other industrial applications where high-temperature performance, reliability, and long service life are essential.
