What is forging?
Forging refers to the processing method in which the metal is deformed by impact force or pressure between the upper and lower anvil iron or forging die. It can be divided into free forging and model forging two kinds.
Free forging: refers to the deformation of the processed metal under pressure between the anvil iron, and the metal can flow freely in all directions of the horizontal plane, so it is called free forging. Under this method, the quality of the product is completely determined by the technical level of the worker, the labor intensity is very high, and the productivity is low. Can not get more complex shape, mainly used for single piece, small batch production and repair work. There are also large forgings, free forging is the only way. Free forging is also divided into two kinds of manual forging and machine forging. Model forging is to make the metal bad material in the upper and lower forging die forced plastic flow molding, so as to obtain the forging with the shape of the die, referred to as die forging. It can be divided into two kinds of fixed die forging and tire die forging. Most stainless steel is used after forging. Compared with carbon steel, stainless steel has different characteristics: low thermal conductivity, narrow forging temperature range, strong overheating sensitivity, high temperature resistance, low plasticity, which have brought many difficulties to forging production, and different types of stainless steel forging processes are also different. Stainless steel forging is much more difficult than carbon steel or low alloy steel, this is because stainless steel at high temperature or in forging, its microstructure at a higher limit temperature still has a higher strength, different types and different components of stainless steel, with different malleability and different forging loads.
