Hot Tensile Testing Machine

65% of industrial product failures are caused by incorrect judgment of the material's high-temperature properties - this data highlights the significance of high-temperature testing. Traditional constant-temperature tests cannot simulate the thermal stress damage of materials during actual use, while the hot tensile testing machine solves industry problems through its three core capabilities:

The combustion chamber components of aircraft engines need to withstand temperatures above 1800℃, while the materials of wind turbine gearboxes undergo cyclic changes ranging from -40℃ to 120℃ - the equipment can cover the entire temperature range from 300℃ to 3000℃ for testing, combined with an inert gas protection system, precisely simulating complex environments such as oxidation and corrosion, avoiding the fatal error of "applying low-temperature data to high-temperature scenarios". A power equipment manufacturer once failed to conduct high-temperature tests, resulting in the premature failure of a new type of heat-resistant steel component at 600℃. After optimizing with a high-temperature tensile machine, the component's lifespan was extended by three times.

The hot tensile testing machine can simultaneously measure core parameters such as yield strength, tensile strength, and elongation after fracture under high temperatures, and even capture hidden characteristics such as material creep and fatigue. For example, in the testing of TWIP high-strength steel, the equipment discovered the problem of liquid metal embrittlement caused by zinc coating at 250℃, providing a key basis for the improvement of automotive lightweight body welding processes; while the high-temperature test of Al-SiC nanocomposite materials showed that 3 vol% SiC doping could reduce the strength drop at 270℃ by 8%, indicating the direction for the research and development of aviation lightweight materials.

Whether it is aerospace titanium alloy, power-resistant steel, or advanced high-strength steel for automobiles, the hot tensile testing machine can adapt to different material forms through replaceable fixtures (for stretching, compression, bending, etc.). The laboratory can be used for iterative development of new material formulations, while on the production line, "on-the-fly testing" can be achieved. In outdoor engineering sites, the performance of components can be quickly verified. This completely breaks the limitation of "testing being restricted to fixed locations".

The core competitiveness of the hot tensile testing machine lies in the dual breakthroughs of "temperature control accuracy" and "mechanical measurement accuracy". This is also the technical core that highly-read articles repeatedly emphasize:

The hot tensile testing machine is equipped with a dual-zone heating furnace chamber and an infrared precise temperature measurement system, enabling the temperature deviation within the gauge length of the sample to be ≤ 5℃, far exceeding the industry standard of ±25℃. To meet the demand for extremely high temperatures, it can achieve stable temperature control of up to 3000℃, with a heating rate of 50℃/min. It can complete the simulation of a temperature rise from room temperature to 1600℃ within 10 minutes, increasing the testing efficiency by 40%.
It is equipped with high-precision strain gauge sensors, with a measurement accuracy of 0.02% FS, in line with international standards such as ASTM E21 and ISO 6892-2. The data repeatability error is ≤ 0.3%. Combined with the built-in extensometer, it can directly measure the true strain in the high-temperature furnace, avoiding "error amplification caused by indirect calculation". A certain aero-engine enterprise reported that after using this equipment, the deviation of material yield strength testing decreased from ±3% to ±0.5%.
The innovative dual-furnace configuration design allows the secondary furnace to complete the sample heating and insulation simultaneously during the main furnace testing process, eliminating the need to wait for the furnace chamber to cool down. The single batch testing time is shortened from 40 minutes to 15 minutes. Combined with the quick sample changing adapter, the fixture changing time is less than 2 minutes, meeting the high-frequency requirements of the automotive manufacturing industry's "batch quality inspection" and research institutions' "multiple experiments".
