how to choose orging materials?


Forging materials are mainly carbon steel and alloy steel of various compositions, followed by aluminum, magnesium, copper, titanium, etc. and their alloys, iron-based superalloys, nickel-based superalloys, and cobalt-based superalloys. Deformed alloys are also forged. Or the rolling method is completed, but these alloys are relatively difficult to forge due to their relatively narrow plastic zone, and the heating temperature, opening forging temperature and final forging temperature of different materials have strict requirements.

The raw state of the material is bar, ingot, metal powder and liquid metal. The ratio of the cross-sectional area of the metal before deformation to the cross-sectional area after deformation is called the forging ratio.

Correct selection of forging ratio, reasonable heating temperature and holding time, reasonable initial forging temperature and final forging temperature, reasonable deformation amount and deformation speed have a lot to do with improving product quality and reducing costs.
