GB/T 15824-2008
ActiveThermal fatigue testing method for hot die steel
热作模具钢热疲劳试验方法
Application Summary AI generated
This standard specifies the method for testing the thermal fatigue resistance of hot die steel, including specimen preparation, heating and cooling cycles, and crack evaluation criteria. It is applied in the metallurgy and tooling industries to assess the durability of steels used in hot forging, die casting, and extrusion dies under repeated thermal shock conditions. The test results help manufacturers select or qualify materials for high-temperature tooling applications where thermal cycling leads to cracking and failure.
