What are the advantages of forgings and why should forgings be selected?

Dalian forgings are widely used in building materials industry. Conceptually, a forging is a metal that exerts pressure to create a desired shape or appropriate compression through plastic deformation.

Dalian forgings use forging equipment to forge bars. Generally, more complex workpieces cannot be forged and require a large amount of processing. However, the forgings have a dense organizational structure and are not prone to internal defects. They are widely used in valve seats, valve cores, valve stems and other valve seats, valve cores, and valve stems. In high-pressure and strongly corrosive alloy valves, forged valve bodies are also widely used.

Compared with castings, forged valves have more uniform body structure, better density, better strength integrity, better dimensional characteristics and smaller dimensional error. Directional structures (pipes) have higher performance than castings in terms of overall strength and stress.

High strength - hot forging promotes crystallization and grain refinement, enables materials to achieve strength and consistency, and reduces changes between parts. The particle flow along the contour of the valve body is beneficial to reduce the occurrence of fatigue or common faults.

Structural integrity - forging eliminates internal defects, produces a consistent metallographic structure, and ensures excellent performance. In places with severe stress and crystal corrosion, forgings can ensure long service life and trouble free service.

Reliability - structural integrity forging eliminates internal defects, produces a consistent metallographic structure, and ensures excellent performance. In places with severe stress and crystal corrosion, forgings can ensure long service life and trouble free service.

Quality assurance - through the use of forgings, their consistency and high quality, the X-ray requirements for class 1 castings have disappeared. The U.S. Navy holds the same attitude when using forgings on nuclear and nuclear power plants. For finished forgings, all ASME code requirements are ultrasonic inspection (U.T.), magnetic particle (M.T.) or liquid penetrant test (P.T.). Scrap forgings found by U.T., M.T., or P.T. methods are rare. The delivery time of parts procurement can be controlled, so the delivery of valves is more reliable.
