The most important characterisitics required for forged hardened steel rolls for cold strip mill are high wear and abrasion resistibility, high resistibility against heat cracking caused by rolling accidents and an enough depth of fully hardened layer. In case of a dull surfaced roll, an important factor is that the roll works effectively for easy dull surfacing and keeps a long life. The experimental data on the effects of alloy elements as dissolved in matrix show that, a roll steel of the following chemical composition gives most excellent properties for the above-mentioned requirements ; 0.8% C-1.0% Si-2.2% Cr-0.25% Mo-1.5% Co. Shore hardness reading on the roll surface always varies depending on residual stress. Therefore, much attention should be given to compressive because it has a serious effect on the hardness of a forged hardened roll regarding its dull surfacing work.
