What is Stainless Steel Forging ?
Steel forging refers to the stainless steel object which is pressed by stainless steel material and molded or compressed by plasticity.
This force is usually achieved by hammering or pressure. Through forging, the defects such as porosity in the smelting process can be eliminated and the microstructure can be optimized. At the same time, due to the preservation of metal flow lines, the mechanical properties of stainless steel forgings are generally better than those of the same alloy castings.
For many parts with strict working conditions, except for the plate with simple shape that can be rolled, forgings are often used.
Stainless Steel Forging Process
- Heating steel alloys to liquid state to improve grain structure in steel
- Guide liquid steel into precision die
- Beat precision dies many times to shape liquid steel
- Complete cooling to form stainless steel forgings

Advantages
Oxidation protection layer
Stainless steel forgings contain an oxidation protection layer, which helps to improve the corrosivity of the alloy steel itself. It can be exposed to corrosive environment for a long time, such as valves, chemical processing equipment, marine equipment, etc
High heat resistance
Stainless steel forgings maintain high heat resistance when used in heat exchangers, furnaces and ovens.
High strength
This process produces a unique and continuous grain flow, which follows the stainless steel forging, thus improving the strength.
Mechanical properties
Steel forgings can produce higher strength to weight ratio and improve the mechanical properties of stainless steel itself.
