Forging pipe fittings and casting pipe fittings, in general, the mechanical properties of castings are lower than those of the mechanical properties of forgings. In addition, forging processing can ensure the continuity of the metal fibrous tissue, fibrous tissue to forging and forging shape consistency, metal streamline integrity, can ensure the parts with good mechanical properties and long service life by precision forging, cold extrusion, forging temperature and extrusion process production, casting is incomparable.
Forgings are made by forging methods. Forging is a force that is used for forging.
The microstructure and mechanical properties of the metal can be improved after forging. Metal fibrous tissue after forging method of hot deformation due to metal deformation and recrystallization, the coarse dendrite and columnar grains turned into finer grain size, uniform equiaxed grain, so that the original ingot segregation, porosity, porosity, slag compaction and welding, the microstructure became more closely, improve the plasticity and mechanical properties of metals.
Casting is made by casting method. Casting is a mold or mold, pouring molten steel into the inside, casting out the parts.
casting
The process of melting the metal into a liquid that meets certain requirements and casting it in a mold with a predetermined shape, size, and performance, after cooling, solidification and finishing.
forging
Use of metal billets forging machinery pressure, the processing method of plastic deformation in order to obtain a certain mechanical properties, shape and size of forging.
