At Titan Metallurgy we offer mechanical testing in three categories. We meet common ASTM International standards for these tests.
- ASTM E8/E8M
- E18-02 (Rockwell)
- E10-01 (Brinell)
Charpy impact tests
- ASTM E 23
A precision machined sample bar with precise dimensions is clamped into the test equipment, which pulls on each end until the piece fails. Titan’s equipment normally pulls to 60,000 pounds on samples with diameters of .505 in. The resulting test report will include the force at the time of the break, yield point, the physical length the sample was stretched before and after breaking, and the change in the diameter of the sample at the break point.
The test equipment applies a constant pressure to a sample through a tungsten ball or diamond indentor. The hardness machine measures the hardness on one of two Rockwell scales: B or C.
The test equipment applies a constant pressure through a tungsten ball to the metallurgical sample being tested. The technician electronically measures the circumference of the dimple to determine the hardness.
A calibrated pendulum swings from a set height and strikes the machined sample at a calibrated V-notch, breaking it. The energy transferred to the material can be inferred by comparing the difference in the height of the hammer before and after the fracture (energy absorbed by the fracture event).
Samples are precisely machined before the test and can be pre-chilled in a cooler to -70° F to test the steel’s performance under extreme conditions. They may also be heated in a furnace to determine how heat treatments change the results.
