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.


Why use forgings?

Forging offers uniformity of composition and structure. Forging results in metallurgical recrystalisation and grain refinement as a result of the thermal cycle and deformation process. This strengthens the resulting steel product particularly in terms of impact and shear strength.

Forged steel is generally stronger and more reliable than castings and plate steel due to the fact that the grain flows of the steel are altered, conforming to the shape of the part.

The advantages of forging include:

Generally tougher than alternatives

Will handle impact better than castings

The nature of forging excludes the occurrence of porosity, shrinkage, cavities and cold pour issues.

The tight grain structure of forgings making it mechanically strong. There is less need for expensive alloys to attain high strength components.

The tight grain structure offers great wear resistance without the need to make products “superhard” We have found that, on a blank HRC 38-42 forged grinder insert wear/wash is about the same as a high alloy HRC 46-50 cast grinder insert. The difference being a HRC 46-50 casting does not have the ductility to handle high impact grinding.


Forging Materials and applications

Forging of steel

Depending on the forming temperature steel forging can be divided into:

A. Hot forging of steel

1. Forging temperatures above the recrystallization temperature between 950–1250 °C

2. Good formability

3. Low forming forces

4. Constant tensile strength of the workpieces

B. Warm forging of steel

1. Forging temperatures between 750–950 °C

2. Less or no scaling at the workpiece surface

3. Narrower tolerances achievable than in hot forging

4. Limited formability and higher forming forces than for hot forging

5. Lower forming forces than in cold forming

C. Cold forging of steel

1. Forging temperatures at room conditions, self-heating up to 150 °C due to the forming energy

2. Narrowest tolerances achievable

3. No scaling at workpiece surface

4. Increase of strength and decrease of ductility due to strain hardening

5. Low formability and high forming forces are necessary

For industrial processes steel alloys are primarily forged in hot condition. Brass, bronze, copper, precious metals and their alloys are manufactured by cold forging processes, while each metal requires a different forging temperature.
