I. Main Material Types
1. Carbon Steel Forgings
Common grades: 20#, 35#, 45#, Q355B, etc. These materials offer good plasticity, weldability, machinability, and cost advantages. They are suitable for atmospheric pressure vessels, general machinery cylinders, pipe sleeves, and other normal temperature, medium/low pressure, non-corrosive working conditions.
Typical properties: 20# steel tensile strength 410-550 MPa; 45# steel hardness HB220-250 after quenching and tempering; Q355B tensile strength 470-630 MPa.
2. Alloy Structural Steel Forgings
Common grades: 35CrMo, 42CrMo, 40CrNiMoA, 34CrNi3Mo, etc. By adding alloying elements such as Cr, Mo, Ni, and Mn, these materials significantly improve strength, hardenability, toughness, fatigue resistance, and wear resistance. They are the mainstream materials for high-pressure vessels, heavy machinery, wind power, and marine applications.
Typical properties: 42CrMo tensile strength 900-1080 MPa and yield strength ≥ 700 MPa after quenching and tempering.
3. Heat-Resistant Steel Forgings
Common grades: 15CrMo, 12Cr1MoV, P91, P92, SA-182F11, etc. These materials feature high-temperature strength, creep resistance, hydrogen corrosion resistance, and oxidation resistance, making them suitable for high-temperature and high-pressure scenarios at 550-650°C.
Typical applications: 12Cr1MoV is used for boiler drums and high-temperature steam cylinders; P91 is the core material for supercritical thermal power generation.
II. Application Fields
Automotive Manufacturing: Engine systems (camshafts, crankshafts), steering systems (steering knuckles), transmission systems (drive gears), etc. Approximately 17%-19% of automotive components are forgings.
Aerospace Manufacturing: Components requiring high temperature, high pressure, and high load resistance, such as aircraft engines and landing gear.
Petrochemical Industry: Equipment such as hydraulic valves, oil pipes, and centrifuge valves.
Heavy Machinery: Core load-bearing components in petroleum, chemical, power, and marine industries, such as cylindrical shell forgings.
III. Forging Process Classification
Open Die Forging: Uses simple universal tools or applies force between anvils to deform the billet. Suitable for forgings with simple shapes.
Closed Die Forging: Includes hot die forging (performed at high temperatures, capable of processing large and complex forgings), warm forging, and cold forging (high precision and good surface quality).
Special Forging Processes: Such as roll forging (pre-forming process), cross wedge rolling, radial forging, etc.
Forgings are widely used in the manufacturing process of components requiring high strength and high durability, serving as essential foundational parts in modern industrial manufacturing.
