MECHANICAL TESTING

 

Mechanical testing is a general term for a number of different tests that determine the  various mechanical properties of a metal. It is a measure of the response to a loading  condition. Midwal Engineering routinely assess mechanical properties, including strength,  hardness, ductility, impact resistance, elongation, stress etc. 

 

The following mechanical tests are available:

tensile

 

Tensile Testing

Tensile testing is used to check the strength and ductility of  metals  under  uniaxial  tensile  forces.  The  sample  is  subjected to uniaxial tension until the point of failure.  This test is used to assess Ultimate Tensile Strength,  Yield Strength, Reduction of Area and Elongation 

Test Methods / Specifications are ASTM E8, ASTM A370,  EN 10002-1, ISO 6892-1

bend

 

Bend Testing

A bend test measures the ductility of a material by bending  it over a given radius. It is a simple qualitative test that is  used to evaluate the ductility and soundness of a metal.  

Test Methods / Specifications are ASTM E190, ASTM E290.

charpy

 

Charpy Impact Testing

 

Charpy Impact Testing measures a material’s toughness,  the  ability  to  absorb  energy,  and  resistance  to  brittle  fracture.  The  test  involves  fracturing  notched  test  specimens at a set temperature with a swinging pendulum.  The  amount  of  energy  absorbed  by  the  material  during  fracture is measured.

Test Methods / Specifications are ASTM A370, ASTM E23,  ISO 148

 

Hardness Testing 

 

Hardness  Testing measures  a  material’s  resistance  to indentation. Midwal Engineering offers the following micro and macro hardness tests:

  • Rockwell – ASTM E18
  • Brinell – ASTM E10
  • Vickers – ASTM E92, ASTM E384
  • Leeb – ASTM A956
Flattening

 

Flattening

 

Flattening is a test for the ductility and soundness of pipes when cold pressed between two parallel plates.

Test Methods / Specifications are ASTM A53 and ASTM A370
