Best for general purpose.used in the front seconds of good mills and in the rear stands of common mills.

 Recommended applications of grade for carbide roll rings:

Grade	Density   (g/cm³)	Hardness   (more than HRA)	Strength   (Mpa)	Recommended application
YGH20	14.30-14.50	86.5	2500	Maximum hardness,excellent wear resistance.used in the last 1-2 stands of good high speed bars.
YGH25	14.10-14.30	85.5	2520	Higher wear resistance.moderate impact resistance in the series.used in the last 1-3 stands of good high speed bars.
YGH30	13.90-14.10	84	2520	Moderate wear resistance and impact resistance.Good for general purpose.used in the last 1-4 stands or all stands or finishing mills.
YGH40	13.60-13.80	83.5	2570	Best for general purpose.Used in the front stands of good mills and in the rear stands of common mills.
YGH45	13.45-13.65	82.5	2570	Used in the first and second stands of finishing mill and in the stands of pre-finishing rolling mills . For every milling lines for low speed rolling, low precision and unstable operation.
YGH55	12.90-13.10	81	2570	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 cribbed steel.
