Refers to those properties of the material's ability to withstand various processing and handling.
Casting performance: Refers to some technological properties of whether the metal or alloy is suitable for casting, mainly including flow performance, ability to fill the mold; shrinkage, the ability to shrink the volume of the casting when it solidifies; segregation refers to the inhomogeneity of the chemical composition.
Welding performance: refers to the characteristics that two or more metal materials are welded together by heating or heating and pressure welding, and the interface can meet the purpose of use.
Top Gas Section Performance: Refers to the performance of metal materials that can withstand upsetting without breaking.
Cold bending performance: refers to the performance of metal materials that can withstand bending without cracking at room temperature. The degree of bending is generally expressed by the ratio of the bending angle α (external angle) or the diameter of the bending center d to the thickness a of the material. The larger a or the smaller d/a, the better the cold bending property of the material.
Stamping performance: the ability of metal materials to withstand stamping deformation without breaking. Stamping at room temperature is called cold stamping. The inspection method is inspected by the cupping test.
Forging performance: the ability of metal materials to withstand plastic deformation without breaking during forging.
chemical properties
Refers to the resistance of metal materials to chemical or electrochemical reactions when they are in contact with the surrounding medium.
Corrosion resistance: refers to the ability of metal materials to resist corrosion by various media.
Oxidation resistance: refers to the ability of metal materials to resist the formation of oxide scales at high temperatures.
