Metal mechanics testing
The mechanical properties of materials refer to the mechanical characteristics of materials when they are subjected to various applied loads (tensile, compression, bending, torsion, impact, alternating stress, etc.) under different environments (temperature, humidity, medium).

Material mechanical properties test:
Hardness, strength and elongation, impact toughness, compression, shear, torsion test Hardness test
Brinell hardness, Rockwell hardness, Vickers hardness, micro hardness hardness test
Yield strength, tensile strength The tensile test is based on the standard:
Metal:
GB / T 228-02, ASTM E 8M-08, ISO 6892-2009, JIS Z 2241-98
Non-metal:
ASTM D 638-08, GB / T 1040-06, ISO 527-96, ASTM D 5034-09, ASTM D 638-08, GB / T 1040-06, ISO 527-96

Common test equipment:
Material universal testing machine, impact testing machine, fatigue testing machine, full Rockwell hardness tester, Vickers hardness tester, Brinell hardness tester, Leeb hardness tester

Metal mechanical properties test:
Metal mechanical performance testing, for the development and development of new metal materials, improving the quality of materials, maximizing the potential of materials (selecting the appropriate allowable stress), analyzing the failure of metal parts, ensuring the rational design of metal parts, and the safety and reliability of use and maintenance All are essential means (see the characterization of metal mechanical properties).

Routine test items:
Hardness (Brinell hardness, Rockwell hardness, Leeb hardness, Vickers hardness, etc.)
Normal temperature stretching, high temperature stretching, low temperature stretching
Bending, impact (normal temperature impact, low temperature impact, high temperature impact) fatigue
Cup protrusion, deep drawing and deep drawing load, cone cup, reaming, compression, shearing, twisting, flattening
Fastener mechanical performance test and welded plate (tube) mechanical properties (deformation, fracture, adhesion, creep, fatigue)
