SAE 8620 is a low-alloy, nickel-chromium-molybdenum steel that is widely used for a variety of applications requiring strength, toughness, and high wear resistance. This steel grade has good machinability, good toughness and strength, and good resistance to wear and abrasion. It is also heat treatable and can be easily hardened to a high strength level.
Applications of SAE 8620 alloy steel bright bar:
Some typical applications of SAE 8620 alloy steel bright bar include:
1. Gears: SAE 8620 is often used in the production of gears and other mechanical components.
2. Shafts: SAE 8620 is well suited for use in the manufacture of shafts and other machine components.
3. Bearings: Due to its good toughness and wear resistance, SAE 8620 is a popular choice for use in bearings and other components that require these properties.
4. Forgings: SAE 8620 is widely used for forging applications due to its good strength, toughness, and ease of forging.
