Why choose forgings? Forgings have many applications in life. Compared with castings, the body of forging valves has a more uniform structure, better density, better strength integrity, better dimensional characteristics, and smaller dimensional errors. Oriented constructions (pipes) have higher performance than castings in overall strength and stress. Forgings need to be consistent from piece to piece, without any porosity, excess space, inclusions or other imperfections. This method produces components with a high strength-to-weight ratio.








Next, I will introduce the excellent performance of forgings to you.
1. High strength
Hot forging promotes crystallization and grain refinement, allowing the material to achieve the greatest possible strength and consistency with minimal piece-to-piece variation. Particle flow precisely follows the contour of the valve body, and these continuous streamlines help reduce the incidence of fatigue or common failures.

2. Reliability
The forgingability that can meet the requirements of the design structure has always been one of the most important advantages of forgings, and to some extent, it ranks first in the above characteristics
​​
3. Structural Integrity
Forging eliminates internal defects and produces a coherent and consistent metallographic structure that guarantees excellent performance. Where stress and intra-crystal corrosion are serious issues, forgings are guaranteed to provide long service life and trouble-free service.

4. Consistency
The dimensional consistency of closed-die forging results in complete control of critical wall thicknesses, avoiding defects caused by core displacement in the casting process, and ensuring no internal defects through high-quality, non-separating ingots and impact force from 10,000 to 30,000-ton presses and consistent metallographic structure.
The quality of forgings is guaranteed, and the use of forgings is also consistent and high-quality.
