8620 Round Bar Full Size Stock-ASTM A29
8620, also known as SAE/AISI 8620, is a typical low-carbon alloy carburizing steel.
As a nickel-chromium-molybdenum alloy, 8620 steel’s composition makes it a representative material offering both internal and external advantages: after carburizing, it forms a high-hardness, wear-resistant layer (HRC 58-62) on the surface, while retaining the toughness of low-carbon steel (HB 180-220) in the core. This makes it widely used in automotive, aviation, and construction machinery applications, particularly for parts subject to impact loads and wear.
8620 steel is typically delivered in the annealed (+A) condition, with a hardness of less than 229 HBW.
