1045 steel is a high-quality carbon structural steel with good plasticity and toughness, as well as high strength, suitable for cutting processing. It is widely used in the production of small section quenched and tempered parts with high loads and large normalized parts with low stress, such as shaft parts, air compressor pistons, pump gears, etc. The tensile strength of 1045 steel is 600 megapascals, the yield strength is 355 megapascals, and the elongation is 16%. twelve

1045 steel is widely used in industries such as mechanical manufacturing, automotive manufacturing, steel metallurgy, and shipbuilding. In the field of mechanical manufacturing, it is usually used to manufacture components such as gears, sprockets, reducers, bearings, etc. It is particularly suitable for the spindle and transmission parts of medium-sized machine tools such as large cars, milling, and grinding. In the field of automotive manufacturing, 1045 steel is also commonly used to manufacture automotive transmission shafts, universal joints, impeller shafts, etc. three

In addition, 1045 steel is also applied in the field of mold repair, targeting the model of mold welding material CMC-E45. This is a type of medium hardness steel welding rod with good bonding properties, suitable for air-cooled steel, cast steel, etc. four

It should be noted that 1045 steel has low hardenability and is not suitable for workpieces with large cross-sectional dimensions and high requirements. In terms of heat treatment, 1045 steel can achieve certain strength, toughness, and wear resistance through different heat treatment specifications such as quenching, tempering, and quenching.
