API 598 F304 Stainless Steel Body Forged Bolted Bonnet Class 2500 Socket Weld

The starting point of the forged valve body is to carefully select the appropriate raw materials, usually high-quality carbon steel, alloy steel or stainless steel, etc., these materials by virtue of their own good mechanical properties for the valve body to lay a solid foundation. Selected materials, heated to the appropriate forging temperature range, generally at high temperatures, the metal plasticity is greatly enhanced to facilitate subsequent processing. The use of large-scale forging equipment, such as air hammer, friction press, etc., the raw material for upsetting, pulling long, punching and a series of complex processes, which not only shapes the basic shape of the valve body, but also make the metal internal grain refinement.
