Mechanical Testing

Don’t Just Say It’s Strong: Let Us Prove It

Mechanical testing hardness

Mechanical testing measures the strength, hardness and ductility of materials under various temperature, tension, compression and load conditions. Mechanical testing services provide information about the suitability of a material for its intended application to help companies design products that will perform as expected.

Laboratory Testing Inc. offers a full-range of mechanical testing services including tensile testing, charpy impact testing, hardness testing, fracture toughness and fatigue testing and stress rupture testing to provide customers with important information about the mechanical properties and characteristics of their materials. Our combination of highly experienced technicians, competitive pricing and fast turnaround time provides an ideal solution for your testing needs.

Mechanical Testing Laboratory Capabilities

  • Elevated temperature tensile testingTensile testing of metal parts and specimens in all sizes, from the smallest fasteners to huge tubing and bolts on our 400,000 lb. capacity machines. A 10,000 lb. capacity tensile machine provides plastics testing
  • Elevated temperature tensile testing using a furnace carousel to process up to three samples at once. Samples can be heated to 1800°F
  • Stress rupture testing complies with ASTM standards and is performed at temperatures up to 1850°F
  • Computerized fracture toughness and fatigue testing equipment can generate up to 55,000 lbs. of tensile or compressive force and is used in conjunction with an environmental chamber that controls the test temperature between -250°F and +400°F
  • Rockwell, Brinell & Superficial hardness testing machines are available for metals; a Shore Durometer hardness tester provides plastics testing
  • Charpy impact testing is performed from -452°F to 500°F

Test Specimens for Mechanical Testing

For convenience and quick turnaround, LTI’s full-service Machine Shop is fully staffed on two work shifts to prepare specimens from metals and many plastics for all types of mechanical testing. Test specimens are machined according to ASTM standards A370, E8, E23 and customer specifications, and LTI is PRI/Nadcap accredited for specimen preparation. LTI is also on NIST’s (National Institute of Standards and Technology) Qualified Manufacturers List for Charpy V-notch Impact verification specimens. Heat treating capabilities are also provided.
