Forged stainless steel is a very common processing technology, is the stainless steel material to exert a certain pressure, through the plastic deformation of its forging into the desired shape or the appropriate compression of the object. In fact, the benefits of forging stainless steel are more, not only to eliminate its smelting process in the process of casting loose and other defects, optimize the microstructure, but also to make the mechanical properties of stainless steel forgings are generally better than the same material castings.
For now, you can through a variety of different ways for forging stainless steel, for example, according to the movement of the blank can be divided into free forging, upsetting, extrusion, die forging, closed forging, closed upsetting and so on. Among them, the free forged stainless steel is the use of impact or pressure to make the metal in the upper and lower between the two iron deformation, in order to obtain the required forgings.
In addition, the method of forging stainless steel can also be differentiated according to the different deformation temperature, get hot forging, warm forging and cold forging, etc., which is forged hot steel forged stainless steel temperature higher than the recrystallization temperature of the blank metal; At the recrystallization temperature of the metal; cold forging this is forging stainless steel at room temperature.
Forged stainless steel can improve its organizational structure and mechanical properties, improve the plasticity and mechanical properties of the metal,
This is the ordinary casting process can not do. So, the mechanical properties of the casting is lower than the same material forging mechanical properties.
In addition, forging stainless steel processing to ensure the continuity of metal fiber organization, so that forging the fibrous tissue and forging shape consistent, complete metal line, can ensure that the parts have good mechanical properties and long service life.
