What is Hot Forging

Hot forging can be defined as “a metal shaping process in which a malleable metal part, known as a billet or work-piece, is worked to a predetermined shape by one or more processes such as hammering, upsetting, pressing and so forth where the work-piece is heated up to about 75% of its melting temperature”.

Advantages of Hot Forging

1. Good ductility.
2. Possibility to manufacture customized parts.
3. Excellent surface quality.
4. High formability ratios.
5. Decreased yield strength and thus less energy required.
6. Increased diffusion and thus reduced chemical inhomogeneity.
Application Field
Manufacturing Process
Material Cutting & Heating: Material will be taken from our material warehouse, then cut into required length and heated by medium frequency furnace before forging.
Forging: After heating billets, heated steel bars will be placed under upper and lower dies, and then pressed into desire shape, but redundant material will shown around the product, which is named as flash.
Passivating: The function of passivation is to create a very thin, dense film on the surface of the metal with good coating performance, which can firmly adhere to the surface of the metal.To restore as far as possible to the factory stainless steel rust resistance, and even beyond the progress.
Blasting & Polishing: To remove the scale and achieve better surface finish, steel forgings will be shot blasted. After shot blasting process, products will look much more clear and smooth. Sometimes special surface treatments are also required according to the application of steel forgings, like color painting, zinc plating,etc.
CNC Machining: Although the tolerances of forging blanks are tighter than that of casting ones, sometimes it is still not enough for application, in this case, machining is needed. In our company, main machining equipment are NC lathe and CNC. NC lathe is used for simple machining, while CNC is for precision machining with high machining cost.

1. What are the most important things to consider when performing hot forging?

1) Production of discrete part.
2) Low to medium accuracy.
3) Low stresses or low work hardening.
4) Homogenized grain structure.
5) Increased ductility.
6) Elimination of chemical incongruities and porosity.

2. What are the best materials for hot forging?

1) Structural steels
2) Aluminum and magnesium wrought alloys
3) Free-cutting steels
4) Stainless steels
5) Titanium alloys
6) Molybdenum alloys
7) Nickel/ cobalt alloys

3. Are there any side effects during hot forging?

1) The functional areas of the component should be machined before assembly, as surface conditions, dimensional tolerances and residual surface contamination are not suitable to usual mechanical assembly design.
2) The material yield is higher than other (warm and cold forging) because of the scale produced during the heating, and because of the subsequent machining.

4. Why are iron and its alloys almost hot forged?

This is for two reasons:
1) First, if work hardening were allowed to progress, hard materials such as iron and steel would become extremely difficult to work with.
2) Secondly, steel can be strengthened by other means than cold-working, thus it is more economical to hot forge and then heat treat. Alloys that are amenable to precipitation hardening, such as most alloys of aluminum and titanium, can also be hot forged and then hardened. Other materials must be strengthened by the forging process itself.

5. Why is forged metal stronger than cast or machined metal?

This stems from the grain flow caused through forging. As the metal is pounded the grains deform to follow the shape of the part, thus the grains are unbroken throughout the part. Some modern parts take advantage of this for a high strength-to-weight ratio.

6. What are the main difference between hot and cold forging?

The cold forging manufacturing process increases the strength of a metal through strain hardening at a room temperature. On the contrary the hot forging manufacturing process keeps materials from strain hardening at high temperature, which results in optimum yield strength, low hardness and high ductility. Which forging method to apply is based on the required functions of the desired component, the industry and if it’s a mass production or a low volume of customized parts.
