30CrMo is an alloy structural steel, the "30" in its name means that the carbon content is roughly 0.3%, while "CrMo" means that the main alloying elements are chromium (Cr) and molybdenum (Mo). This steel is known for its high strength, high hardness and excellent wear resistance.
Features of 30CrMo steel plate:
Strength and hardness: 30CrMo alloy steel has high strength and hardness, which can meet the application needs of high mechanical properties.
Hardenability and tempering stability: The steel has good hardenability and tempering stability, which means that it can obtain a more uniform hardness and strength distribution through heat treatment, and maintain good performance stability.
Corrosion resistance: The alloying of chromium and molybdenum makes 30CrMo have good corrosion resistance and can maintain stable performance in a variety of environments.
Processing performance: The processing performance of 30CrMo is good, and it can be convenient for cutting, welding and other process operations.
The chemical composition of 30CrMo alloy steel mainly includes carbon (C) 0.26~0.34%, silicon (Si) 0.17~0.37%, manganese (Mn) 0.40~0.70%, chromium (Cr) 0.80~1.10%, molybdenum (Mo) 0.15~0.25% and so on. These elements are present in a certain proportion in steel and together determine the properties of steel.
30CrMo alloy steel is usually delivered in a hot-rolled state and then subsequent heat treatment (such as quenching and tempering) is performed as needed to achieve the desired mechanical properties.
30CrMo steel plate application:
Heavy machinery: Due to its high strength and wear resistance, 30CrMo alloy steel is widely used in the manufacture of key components in heavy machinery, such as crankshafts, connecting rods, gears and bushings.
Petrochemical: In the petrochemical industry, 30CrMo alloy steel is often used to make components in equipment such as high-pressure vessels, boilers and oil pipelines.
Energy field: In the energy field, such as wind power, nuclear power, etc., 30CrMo alloy steel is also used to manufacture a variety of parts that require high strength and wear resistance.
Automotive industry: 30CrMo alloy steel is also commonly used to manufacture components such as automotive engines, drivetrains and suspension systems to improve vehicle performance and safety.
In short, 30CrMo alloy steel has an important position in industrial production with its excellent properties and wide application fields.
