Sim? ilarly, an increase in case depth, particularly uneven case depth in casehardeningsteels, increases warpage on quenching.
与此类似，渗碳层厚度越大，特别是对于渗碳层厚度不一的渗碳用钢，淬火时更易产生翘曲。

The lower heat-treating temperature of the case results from the fact that hypereutectoid steels are normally austenitized for hardening just above the lower critical point.
由于恰好高于低临界温度通常使过共析钢奥氏体化而硬化，所以对外层采用较低的热处理温度。

Fatigue properties of three casehardeningsteels for heavy duty gears after carburization were investigated by means of rotating bending fatigue tests.
