Casting properties: refers to whether the metal or alloy is suitable for casting some process properties, mainly including flow properties, the ability to fill the casting mold; shrinkage, the ability of volume shrinkage when the casting solidifies; deviation refers to chemical composition unevenness.
Welding performance: refers to the metal material by heating or heating and pressurized welding method, two or more metal materials welded together, the interface can meet the characteristics of the purpose of use.
Top gas section performance: refers to the performance of the metal material can be granted top forging without rupture.
Cold bending performance: refers to the metal material at room temperature can withstand bending without rupture performance. Bending degree is generally used to bend the angle α (outer angle) or bending center diameter d to the material thickness a ratio, a the greater or d / a smaller, the better the cold bending of the material.
Stamping performance: the ability of metal materials to withstand stamping deformation processing without rupture. Stamping at room temperature is called cold stamping. The test method is to test by cupping test.
Forging performance: the ability of the metal material to withstand plastic deformation without rupture during forging processing.
