9310 steel vs carpenter 158
ASTM A646 (9310-2) SAE J1397 (9310) SAE J404 (9310) AISI E9310 Uses. One of the main applications of AISI E9310 is manufacturing aircraft components, including gears, shafts, and bolts. The alloy is also used in high-stress applications, such as heavy-duty machinery, oil and gas drilling equipment, and racing engines.Carpenter 158 was originally developed as a dies steel and when carburized is best suited for application requiring high core strength and subjected to heavy shock and wear. Carburized 9310 is a very good steel when high core strength, toughness, fatigue, and wear properties are required. It's biggest use is in heavy duty gears and crankshafts.Carpenter 158 is a chrome-nickel alloy steel with an analysis representing the best case hardening steel known for parts subject to heavy shock and wear. This alloy is ideally …
