水溝蓋板模具疲勞斷裂性能：模盒工作過程中，在循環應力的長期作用下，往往導致疲勞斷裂。其形式有小能量多次沖擊疲勞斷裂、拉伸疲勞斷裂接觸疲勞斷裂及彎曲疲勞斷裂。模盒的疲勞斷裂性能主要取決于其強度、韌性、硬度、以及材料中夾雜物的含量。

Fatigue fracture property of the ditch cover mould: fatigue failure is often caused by the long-term effect of cyclic stress during the operation of the mould box. Its form is small energy, multiple impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture and bending fatigue fracture. The fatigue fracture properties of the mould box mainly depend on its strength, toughness, hardness, and the content of inclusions in the material.

水溝蓋板模具高溫性能：當模盒的工作溫度較高進，會使硬度和強度下降，導致模盒早期磨損或產生塑性變形而失效。因此，模盒材料應盒有較高的抗回火穩定性，以保證模盒在工作溫度下，盒有較高的硬度和強度。

The high temperature performance of the groove cover die: when the working temperature of the mold box is higher, the hardness and strength will decrease, resulting in the failure of the early wear or plastic deformation of the mold box. Therefore, the box material should have higher resistance to tempering, so that the mold box has higher hardness and strength at the working temperature.
