Application：
1)Gears: 38CrMoAl steel is commonly used in the manufacture of high-strength and wear-resistant gears, especially for gears in heavy machinery and automotive transmission systems.
2) Shaft: Because the steel has good strength and toughness, it is suitable for manufacturing shafts that withstand high loads and high speeds, such as automobile drive shafts, motorcycle engine shafts, etc.
3) Pins and bolts: 38CrMoAl steel is commonly used in the manufacture of connecting parts, such as pins and bolts, for the connection of mechanical parts.
4)Cylinder and crankshaft: This steel can provide good wear resistance and strength when manufacturing cylinder blocks and crankshafts of internal combustion engines.
5)Bearings and nuts: Because 38CrMoAl steel has high hardness and wear resistance, it is commonly used in the manufacture of bearings and nuts.
6)High-pressure screw: Due to the high strength and toughness of the steel, it is suitable for the manufacture of high-pressure screws and is used in the engineering and construction fields.
7)Hydraulic cylinder: 38CrMoAl steel can also be used to manufacture hydraulic cylinders for construction machinery and hydraulic equipment.
8)Injection molds: Due to their wear resistance and heat resistance, 38CrMoAl steel is commonly used in the manufacture of plastic injection molds to withstand high pressure and high temperature working environments.
