      basic introduction

      Through various mechanical tests to determine the various mechanical performance criteria of metal materials. The properties of metal related to elasticity and inelasticity and related to stress-strain are all mechanical properties of metal. In the process of researching and developing new materials, improving material quality, designing and using metal parts, etc., mechanical properties are the most important performance indicators, and are indispensable items in the performance testing of metal plastic processing products. Mechanical performance tests generally include tensile test, torsion test, compression test, impact test, hardness test, stress relaxation test, fatigue test, etc. Stress relaxation test and fatigue test do not belong to the routine mechanical properties inspection of materials.

      Test items

      Hardness Testing

      Hardness is a characterization of the ability of a metal to resist deformation or cracking in a local volume of the surface. It not only has an approximate empirical relationship with the static strength and fatigue strength of the material, but also indirectly exists with process performance such as cold formability, machinability and weldability. Some links. Therefore, the hardness value has certain reference significance for controlling the quality of the hot and cold machining process of the material.

      Elasticity test

      Static stretching can determine the most basic mechanical properties of materials during elastic deformation, plastic deformation and fracture, including elastic modulus, yield strength, tensile strength, elongation and shrinkage rate. These performance indicators are the basic properties inherent in materials and an important basis in engineering design.

      Impact test

      The impact test can obtain dynamic performance indicators such as impact toughness and impact absorption work. It is extremely sensitive to the brittleness tendency issues and the metallurgical quality and internal defects of the material. Approach.
