[0002] Mechanical properties are a set of common indicators of metal materials and are important material property indicators used in the design of mechanical products. In general-purpose mechanical products, mechanical parts are used under normal temperature, normal pressure and non-strongly corrosive media, so generally the special requirements under special use conditions are not considered.

[0003] The property of a metal material to resist damage under the action of a load is called mechanical property (or mechanical performance). The quality of the service performance of a metal material determines its scope of use and service life. The mechanical properties of a metal material are the main basis for the design and material selection of parts. Different external load properties (such as tension, compression, torsion, impact, cyclic load, etc.) will require different mechanical properties of the metal material.
