This high alloy roll material is used for two general types of
mill applications, hot nonferrous work rolls and hot / cold mill
back-up rolls. The “high” temperature properties of this alloy
are designed to enhance both the thermal fatigue strength and
resistance to thermal shock in a hot mill environment. The 5CRMO
alloy has earned worldwide acceptance as the standard alloy of
choice for hot nonferrous work rolls. The 5CRMO alloy should
also be specified for both hot and cold mill back up roll
applications that require optimum fatigue strength and wear
resistance. In back-up roll applications requiring greater that
4” (100mm) total roll life, Grade 5CRMO should be; specified.
