Test project background

   Hardness is a characterization of the ability of a metal to resist deformation or cracking in a local volume on the surface. It not only has an approximate empirical relationship with the static strength and fatigue strength of the material, but also has some indirect relationship with process properties such as cold formability, machinability, and weldability. Some contact. Therefore, the hardness value has certain reference significance for controlling the quality of the material's cold and hot processing technology.

　Static tension can measure the most basic mechanical properties of materials in the process of elastic deformation, plastic deformation and fracture, including elastic modulus, yield strength, tensile strength, elongation and reduction of area. These performance indicators are the inherent basic properties of materials and an important basis in engineering design.

   The impact test can obtain dynamic performance indicators such as impact toughness and impact absorption energy. It is extremely sensitive to brittleness tendency issues, material metallurgical quality, and internal defects that are crucial in the use of materials. It is very convenient to check material brittleness tendency and metallurgical quality Way.

　Testing equipment: material universal testing machine, impact testing machine, fatigue testing machine, full Rockwell hardness tester, Vickers hardness tester, Brinell hardness tester, Leeb hardness tester, etc.

    In addition, the metal laboratory also provides compression test, shear test, torsion test, flattening test, fastener mechanical performance test and welded plate (tube) mechanical performance, including: deformation, fracture, adhesion, creep, Fatigue etc.
