SAE 8620 is a low-alloy steel that is widely used for applications requiring high strength, toughness, and wear resistance. This steel grade is alloyed with elements such as nickel, chromium, and molybdenum, which enhance its hardenability, fatigue resistance, and overall durability. SAE 8620 has a carbon content of approximately 0.20%, making it ideal for carburizing applications, where the steel is hardened on the surface while retaining a tough, ductile core. This makes it suitable for manufacturing components like gears, shafts, crankshafts, and bearings that are subjected to heavy loads and require high wear resistance. SAE 8620 can be heat-treated to achieve the desired hardness, providing flexibility for a wide range of industrial applications. It is commonly used in automotive, aerospace, and machinery sectors where reliability and performance are critical. Available in various forms such as bars, forgings, and plates, SAE 8620 is valued for its versatility, excellent mechanical properties, and ability to withstand demanding operating conditions.
