Forged aluminum valve stems

Introduction to forged aluminum valve stems:
The forged aluminum valve stems component is forged, and a forging press is used to apply pressure to the metal blank to plastically deform it to obtain a forging having a certain mechanical property, a certain shape and a size. Forging and stamping are of the same plastic processing properties, collectively referred to as forging. Forging is a forming method commonly used in mechanical manufacturing. The forging can eliminate the as-cast looseness and weld holes of the metal, and the mechanical properties of the forging are generally superior to those of the same material. For important parts with high load and severe working conditions in machinery, forgings are often used except for the available rolled sheets, profiles or welded parts.

Forged aluminum valve stems advantages:
1. The surface of the forged valve is brighter and the appearance is exquisite
2. The ductility and compression resistance are stronger than cast valves, adapting to high pressure pipelines
3. The disadvantage is that it is only suitable for small diameter pipelines;
Forged aluminum valve stems execution standards:
Experiment and inspection: JB/T 9092 API598
Pressure-temperature: GB/T9131 ANSIB16.34
