Difference between forged and cast pipe fittings

Generally speaking, the mechanical properties of castings are lower than those of forgings of the same material.

In addition, forging process can ensure the continuity of metal fiber structure, keep the fiber structure of forgings consistent with the shape of forgings, complete metal flow line, ensure good mechanical properties of parts and long service life of forgings produced by precision die forging, cold extrusion, warm extrusion and other processes, which are incomparable to castings.

Forging is made by forging. Forging is made by forging with impact force.

The microstructure and mechanical properties of metal can be improved after forging. Due to the deformation and recrystallization of the metal, the original coarse dendrite and columnar grain become equiaxed recrystallization structure with fine grain and uniform size, which makes the original segregation, looseness, porosity, slag inclusion and other compaction and welding in the ingot. The structure becomes more compact and improves the plasticity and mechanical properties of the metal.

A casting is a piece made by casting. A casting is a piece made by pouring molten steel into a mold or model.

Casting Threaded Flange

Casting: the process of smelting metal into a liquid that meets certain requirements and pouring it into the mold, and then cooling, solidification and cleaning to obtain castings (parts or blanks) with predetermined shape, size and performance.

Forging uses forging machine to exert pressure on the metal blank to produce plastic deformation so as to obtain the processing method of forging with certain mechanical properties, certain shape and size.
