在室温和300 °C下，在自配对条件下，评估了三种不同不锈钢（SS 316、316 L和416）的磨损行为。根据ASTM G196-08标准，使用国产磨损测试仪来评估配对材料的磨损性能。在测试期间在线记录摩擦扭矩的变化以评估磨损的开始。磨损50（G50）应力值用于比较材料组合的抗磨损性，并且结果表明温度对测试材料的抗磨损性有显著影响。这是由于在高温下硬度和屈服强度降低，导致钢的软化并限制其抵抗严重变形的能力。结果表明，在磨损过程中，磨损表面发生了严重的塑性变形，磨损机制为粘着磨损。
Galling behavior of three different stainless steels (SS 316, 316 L and 416) was evaluated at room temperature and 300 °C under a self-mated condition. An indigenously fabricated galling tester was used to evaluate the galling performance of mated materials as per ASTM G196-08 standard. The variation in frictional torque was recorded online during the test to assess the onset of galling. The galling50 (G50) stress value was used to compare the galling resistance of a combination of materials, and the results indicate a significant influence of temperature on the galling resistance of the materials tested. This has been attributed to the decrease in hardness and yield strength at elevated temperature which results in softening of the steel and limits its ability to resist severe deformation. Scanning electron micrographs of the galled surface reflected a severe plastic deformation in sliding direction, and a typical adhesive wear mechanism is prevalent during the galling process.
