2. Sort by material
♠♠♠Carbon steel/alloy steel forgings:
such as SAE8620, 4140, 4143, 1.227, 18CrNiMo-6, 16MnCr5, 35MnCr5.
♠♠♠Stainless steel forgings:
such as 304, 316, 2Cr13.
♠♠♠Non-ferrous metal forgings:
aluminum alloy, copper alloy, titanium alloy.
3. Classification by forging process
♠♠♠Free forging: large, single or small batch production (such as hydroelectric spindle).
♠♠♠Die forging: mass production, complex shape (such as cylinder bottom).
♠♠♠Precision forgings: near-net forming to reduce machining allowance (e.g. gear blank).
4. Classification by processing state
♠♠♠Roughing forgings: Further turning/milling required.
♠♠♠Finishing forgings: direct assembly use.
♠♠♠Gear/ring: used for finished product assembly.
5. Special function forgings
♠♠♠High pressure valve forgings: petrochemical pipeline systems.
♠♠♠Wear-resistant forgings: shovel teeth, crusher parts of mining machinery.
♠♠♠ Because of its high strength, fatigue resistance and other characteristics, forgings are the key basic parts of high-end equipment manufacturing, and the technical trend is to lightweight and precision development
