Product Description

        Methods for testing mechanical properties in the processing quality of hot forged metal parts:

Mechanical properties testing
The mechanical properties of forgings are tested to evaluate whether they meet the use requirements. The main testing methods include the following:
Tensile test: Determine the tensile strength, yield strength, elongation and cross-sectional shrinkage of forgings, which reflects the mechanical properties of materials under static tensile loads and is an important method for evaluating the strength and plasticity of forgings.
Impact test: Measure the absorbed energy of forgings under impact loads to evaluate their toughness and brittle transition temperature. For forgings working under dynamic loads, such as mechanical parts and tools, impact toughness is a key performance indicator.
Hardness test: Use a hardness tester to measure the hardness value of forgings, such as Brinell hardness, Rockwell hardness, Vickers hardness, etc. Hardness is an indicator of the material's ability to resist local deformation. It has a certain correlation with the material's strength and wear resistance, and can indirectly reflect the mechanical properties and processing quality of forgings.
Fatigue test: For some forgings that are subjected to cyclic loads, such as engine crankshafts, gears, etc., fatigue tests are required to determine their fatigue limit and fatigue life and to evaluate their reliability during long-term use.
