MECHANICAL TESTING OF METALLIC MATERIALS

Mechanical tests of metallic materials are performed mainly in our laboratory in Jablonec nad Nisou. We perform partial tests and the output is a protocol serving as a basis for inspection report or certification.

What is tested:

• Testing of metallic materials and components at ambient temperature
• Brinell, Rockwell and Vickers hardness test
• Universal tensile/pressure testing of various materials and products to up to 40 tons on universal tearing machines
• Tensile tests, determination of strength limit Rm, yield point ReH, ReL, Rp0.2, ductility A
• Notch toughness test
• Notch toughness test at reduced temperature
• Hardness tests: Hardness values in HB, HRC and HV units
• Tensile tests: Strength limit R_m, Yield points R_eH, R_eL, R_p0.2, Ductility A
• Notch toughness test: Impact energy in J, notch toughness in Jcm²
• Universal tensile/pressure test: Loading, pressure, deflection values, ...
• Inconsistency of the values measured with the values specified in material certificates,
• inspection certificates, manufacturing guidelines, ...
