Grade

Recommended applications
YGH20 Maximum hardness,escellent wear resistance in the series .Used in the last 1-2 stands of good high speed rolling mills for rolling common and hard steel bars.
YGH25 Higher wear resistance,moderate impact resistance in the series.Used in the last 1-3 stands of good high speed finishing rolling mills for rolling common and hard steel bars.
YGH30 Moderate wear resistance and impact resistance .good for general purposes .Used in the last 1-4 stands or all stands of finishing mills.
YGH40 Best for general purpises.Used in the front stands of good rolling mills and in the rear stands of common rolling mills.
YGH45 Used in the first and second stands of finishing rolling mills and in the stands of pre-finishing rolling mills.For every stand of rolling lines for low speed rolling.Low precision and unstable operations.
YGH55 Maximum binder content in YGHseries,good toughness and themal crack resistance.Used in the stands of pre-finishing rolling mills and for roll rings for hot rolling of ribbbed steel.
YGR20 High wear resistance and corrosion resistance.Used in the last 1-2 stands of finishing mills.
YGR25 High wear resistance and corrosion resistance.Used in the last 1-3 stands of finishing mills.
YGR30 Good toughness,wear resistance.corrosion resistance and themal ctack resistacnce Used in the middle and rear stands of finishing mills.
YGR40 Good toughness and themal crack resistance.good for general purpises.Used in most stands of the finishing mills and in the rear stands of common mills.
YGR45 Good toughness and themal crack resistance.Used in the front stands of finishing mills.
YGR55 Good impact resistance.Used in the stands of pre-finishing rolling mills for hot rolling ribbed steel bars and they can be machined with turning and milling.
YGR60 Good impact resistance.Used for hot rolling ribbed steel bars and in the first and second stands of pre-finishing rolling mills.
