The difference between forging and casting material:


The casting metal is formed in liquid casting and casting. It requires good fluidity, filling ability of liquid metal, etc. (also called casting), divided into two cast steel and cast iron in the iron and steel casting, iron carbon content is higher than steel, its low strength over steel, plastic, poor general tolerances for the production is not very big parts, such as machine tools, such as the low pressure valve; Steel casting strength is high, used for making complex parts, such as chain rail, high pressure valve seat, etc.

 

Forging is formed by forging after the metal is heated in solid state. It requires the metal to have good thermoplastic (also known as forging), and the general forging is steel, which is of high strength and plasticity, which is suitable for high quality and high quality components. Such as bolts, shafts, gears, axle, etc.
