The process performance of sheet metal processing materials

① Cold processing
Cold processing refers to a processing process that causes plastic deformation to cause plastic deformation at lower crystallization temperature. Such as cold rolling, cold stroke, cold squeeze, stamping, cutting processing, etc.
Cold processing refers to the ability to meet these processing processes.
② castability
Steel castability means that steel can use casting to obtain the performance of qualified castings.
The castability mainly includes steel liquidity, solidification, contraction and bias.
Liquidity refers to the ability of steel water to be filled with molding. The contraction refers to the degree of volume shrinkage when steel liquid solidification. Poor analysis means that during the cooling solidification process, the chemical composition and tissue's unevenness of the metal internal chemical and tissue are caused by the difference in crystals. Essence The smaller the two -phase area, the better the castability.
③ Forgetisability
Forgedness means that metal materials can change the shape without cracking performance during pressure processing. It includes processing such as hammer forging, rolling, stretching, squeezing and other processing in thermal or cold. The forgedness is mainly related to the chemical composition of metal materials.
④ welding
It means that metal materials can obtain the performance of high -quality welding joints under certain process conditions.
