Mechanical Testing

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

Mechanical testing hardnessMechanical Testing evaluates materials under conditions such as tension, compression and temperature. Laboratory Testing Inc. is equipped to provide the full range of mechanical testing services for metals and alloys with quick, reliable results and certified reports.

LTI’s mechanical testing lab near Philadelphia, PA (USA) routinely assesses mechanical properties, including strength, hardness, ductility, impact resistance, fracture toughness, elongation and stress. The mechanical test results provide valuable information to help customers with selecting material, verifying material from a new supplier or evaluating a heat treat process.

Trust Our Service & Qualifications

The combination of technical expertise, competitive pricing and fast turnaround provides an ideal solution for your testing needs. Standard turnaround time is just three business days, but faster rush services are also available.

Heat treat upgrade capabilityOur qualifications will also meet your requirements, including:

  • NADCAP and A2LA accreditations
  • Testing completed according to ASTM, EN, ISO, MIL, NASM methods and specifications
  • PED approval by Lloyd’s Register
  • Mechanical and materials engineers to help with unique needs and questions
  • Specimen preparation for all mechanical tests

LTI has numerous furnaces to heat treat specimens prior to testing, so customers can compare processes or confirm that material upgrade meets specification or other requirements. Find out more about capability heat treating and testing.

Mechanical Test Capabilities & Ranges

elevated temperature tensile testTensile Testing of specimens and fasteners in all sizes is performed on machines with load capacities from 8 ozs. to 600,000 lbs. A 10,000 lb. capacity tensile machine provides plastics testing.

Elevated Temperature Tensile Testing uses a furnace carousel to process up to three specimens at once. The test samples can be heated to 1800°F.

Stress Rupture and Creep Testing comply with ASTM standards and can be performed at temperatures up to 2000°F.

Fracture Mechanics equipment can generate up to 100,000 lbf. and controls the test temperature between -150°F and +2000°F.

Rockwell, Brinell and Superficial Hardness Testing are available for metals. The Shore Durometer test is performed on plastics.

Impact Testing of Metal is performed at temperatures from -452°F to +500°F, and with impact energy up to 320 ft. lbs. Charpy V-notch, weld charpy and drop-weight testing are available.

Welder & Procedure Qualification is offered per MIL & API specifications, ASME & AWS codes, ASTM & EN standards and the Pressure Equipment Directive.

Test Specimens for Mechanical Testing

LTI’s full-service Machine Shop is fully staffed on two work shifts to prepare precision specimens for all types of mechanical testing. Specimens from metals and many plastics are produced in-house for convenience and quick order turnaround. Test specimens are machined according to ASTM standards A370, E8, E23 and customer specifications. LTI is also on NIST’s (National Institute of Standards and Technology) Qualified Manufacturers List for Charpy V-notch Impact verification specimens.

Extensive List of Mechanical Testing Services

Test results provide information about the suitability of a material for its intended application and help companies design and manufacture reliable products that will perform as expected. All of the services performed in our mechanical testing lab are offered for metallic materials. Tensile and hardness testing are also available for polymers.
