  Material Selection
1.Chemical Composition: 2.Hardness:HRC 63-66
1.Chemical Composition 2.Hardness:HRC 64-67
1.Chemical Composition:2.Hardness:HRC 60-62
MATERIAL : H12(AISI H12,DIN-1.2606)
1.Chemical Composition: 2.Hardness:HRC 56-60
After rolling one short period,the hardness of rolling surface arise 3-4 HRC and strain hardening layer producing causes fatigue effect,which brings crack and spalling.The only way to decrease the possibilities of crack and spalling,elongate the roll¡¯s life is to remove the phase-transformation layer in advance.
