AISI 8620 steel is a low alloy nickel, chromium, crucible surface hardened steel, usually available in a rolled state, with a maximum hardness of HB 255max. The SAE steel 8620 has a high external strength and good internal strength, making it highly resistant to wear. The core strength of the AISI 8620 steel is higher than that of the 8615 and 8617 grades. The steel 8620 is suitable for applications that require both toughness and wear resistance. This level is usually provided as a round stick. Typical applications include: knife rods, bearings, bushings, camshafts, differential pins, guide pins, main pins, piston pins, gears, flower key shafts, ratchets, sleeves and other easy-to-use steels as well as applications that facilitate their processing. Carbide to a controlled surface depth.
