Alloy steel 8620 is available in strips, sheets, plates, round and square bars, seamless and welded pipes & tubes, Forged & buttweld Fittings, flanges, fastener, flat rolled bars, Wire & valves.
Alloy Steel 8620 is Tempering of carburized parts is done at 250 to 300 F and this will result in the alloy having a core strength of approximately 135 ksi minimum with Rockwell C case hardness of 90. Tempering of heat treated and water quenched parts (not carburized) is done at 400 F to 1300 F with greater hardness the lower the tempering temperature.

Principal Design Features AISI 8620 is a hardenable chromium, molybdenum, nickel low alloy steel often used for carburizing to develop a case-hardened part. This case-hardening will result in good wear characteristics. Alloy Steel 8620 Applications In the carburized condition this alloy is used for gears, ring gears, shafts and crankshafts. Alloy Steel 8620 Machinability Machining is done prior to carburizing to within as close a tolerance as possible. Finish machining, after heat treatment and/or carburizing, should be at a minimum so as not to impair the hardened case of the part. Machining may be done by conventional means prior to heat treatment - after carburizing machining is usually limited to grinding. Alloy Steel 8620 Forming Forming characteristics of 8620 alloy are good in the annealed condition. Alloy Steel 8620 Welding The alloy may be welded by conventional methods, usually gas or arc welding. Preheating at 400 F is beneficial and subsequent heating after welding is recommended - consult the approved weld procedure for the method used. Alloy Steel 8620 Heat Treatment This alloy may be hardened by heating to 1500 F followed by a water quench. Carburize at 1650 to 1700 F in an appropriate carburizing medium and oil quench to harden. Improved carburized case and core properties can be obtained by furnace cooling from carburizing at 1650 - 1700 F and then reheating to 1575 F. Alloy Steel 8620 Forging The alloy may be forged at 2200 F down to 1800 F prior to the hardening heat treatment or carburizing. Alloy Steel 8620 Hot Working Hot working may be accomplished prior to hardening or carburizing. Consult the alloy supplier for information as to temperatures. Alloy Steel 8620 Cold Working The alloy may be cold worked in the annealed condition by conventional methods. Cold working, as with machining, should be done to as close a tolerance as possible before heat treatment or carburizing. Alloy Steel 8620 Annealing AISI 8620 may be given a full anneal at 1550 F and slow cooling at not more than 50 F per hour down to 850 F. From there it may be air cooled. Alloy Steel 8620 Aging Not applicable to this alloy. Alloy Steel 8620 Tempering Tempering of carburized parts is done at 250 to 300 F and this will result in the alloy having a core strength of approximately 135 ksi minimum with Rockwell C case hardness of 90. Tempering of heat treated and water quenched parts (not carburized) is done at 400 F to 1300 F with greater hardness the lower the tempering temperature. Alloy Steel 8620 Hardening Hardening is done by oil quench from 1675 F. See "Heat Treatment". Carburizing is accomplished at the same 1650 to 1700 F range in a carburizing "pack" or environment, followed by oil quench for thin sections or a furnace cool for heavier (over 3/4") sections. Following carburizing of heavy sections a reheat at 1575 F will enhance both case and core properties of the alloy. Alloy Steel 8620 Other Comments This alloy is typically used for carburized parts where a hardened case is desired for wear resistance. -
