Process performance

Refers to those properties that the material is capable of withstanding various processing and handling capabilities.

Casting performance: refers to the metal or alloy is suitable for casting some process performance, mainly including flow properties, full mold capacity; shrinkage, the ability of the volume to shrink when the casting solidifies; segregation refers to chemical composition unevenness.

Welding performance: refers to the welding of two or more metal materials together by metal or heat and pressure welding, and the interface can meet the purpose of use.

Top gas segment performance: refers to the ability of metal materials to withstand forging without breaking.

Cold bending performance: It means that the metal material can withstand bending without breaking performance at normal temperature. The degree of bending is generally expressed by the bending angle α (outer angle (or the ratio of the diameter d of the core to the thickness a of the material, the larger a or the smaller the d/a, the better the cold bendability of the material.

Stamping performance: The ability of metal materials to withstand stamping deformation without breaking. Pressing at normal temperature is called cold stamping. The test method was tested by cupping test.

Forging properties: The ability of metal materials to withstand plastic deformation without cracking during forging.

Chemical properties

Refers to the resistance of a metallic material to chemical or electrochemical reactions when it is rubbed against the surrounding medium.

Corrosion resistance: refers to the ability of metal materials to resist various media erosion.

Oxidation resistance: refers to the ability of metal materials to resist the generation of scale at high temperatures.
