Grade Recommended applications
YGH20 Maximum hardness, excellent wears resistance in the series. Used in the last 1-2 stands of good high speed finishing 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 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 purposes, used in the front stands of good mills and in the rear stands of common mills.
YGH45 Used in the first and second stands of finishing mills and in the stands of pre-finishing rolling mills. For every stand of rolling lines for low speed rolling, low precision and unstable operation.
YGH55 Maximum binder content in YGH series, good toughness and thermal crack resistance. Used in the stands of pre-finishing rolling mills and for roll rings for hot rolling of ribbed steel.
