Product Description and Process

SAE 8630 Forging Parts Supplier China

Production process: metal hot forging process (drop forging process)

Machining process: CNC machine, machining center, lathe, mill machine, drill machine, etc.

Surface treatment process: paint coating, electrophoretic coating, electrogalvanizing coating, phosphating, black oxide coating, powder coating, etc.


Product Material and Uses

Normally produce with low carbon steel, medium carbon steel, low alloy steel, such as 1018 steel, 1020 steel, 1035 steel, 1045 steel, 16Mn, 35Mn, 40Mn2, Q235, Q345, A105, 20MnMo, 35Crmo, 42CrMo, 4140 steel, 4340 steel, 8620 steel, etc.

The steel forging products are widely used for auto-car parts, truck parts, train parts, vehicle components, construction machinery components, other machinery components, etc.


Forging Processes

There are many different kinds of forging processes available; however, they can be grouped into three main classes:

Drawn out: length increases, cross-section decreases

Upset: length decreases, cross-section increases

Squeezed in closed compression dies: produces multidirectional flow

Common forging processes include: roll forging, swaging, cogging, open-die forging, impression-die forging, press forging, automatic hot forging and upsetting.


Temperature

All of the following forging processes can be performed at various temperatures; however, they are generally classified by whether the metal temperature is above or below the recrystallization temperature.

If the temperature is above the material's recrystallization temperature it is deemed hot forging.

If the temperature is below the material's recrystallization temperature but above 30% of the recrystallization temperature (on an absolute scale) it is deemed warm forging.

If below 30% of the recrystallization temperature (usually room temperature) then it is deemed cold forging.

The main advantage of hot forging is that it can be done more quickly and precisely, and as the metal is deformed work hardening effects are negated by the recrystallization process.

Cold forging typically results in work hardening of the piece.
