Mechanical property test

Test project background

Hardness is the ability of metal to resist deformation or fracture in the 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 has some indirect relationship with the cold formability, machinability, weldability and other technological properties. Therefore, the hardness value has a certain reference significance for controlling the cold and hot processing quality of materials.

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 indexes are the basic properties of materials and the important basis in engineering design.

Impact test can obtain dynamic performance indexes such as impact toughness and impact absorption energy. It is very sensitive to the brittle tendency, metallurgical quality and internal defects of materials, which are very important in the use of materials. It is a very convenient way to check the brittle tendency and metallurgical quality of materials.

Testing equipment: material universal testing machine, impact testing machine, fatigue testing machine, all 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, mechanical properties test of fasteners and mechanical properties of welded plate (pipe), including deformation, fracture, adhesion, creep, fatigue, etc.
