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
