| 1. Characteristics | |||||||
| a, High resistance of tempering softenng properties(the using temperanture can improve 50ºC than that of H13 steel). | |||||||
| b, Excellent Thermal Stability:Heat preservation in the long time of 620ºC,the hardness is always higher than that of H13,and still maintain in 35HRC above. | |||||||
| c, Excellent thermal fatigue resistance:The thermal fatigue resistance is better than that of H13 steel. | |||||||
| 2. Applications | |||||||
| Forging die,casting die,hot squeezing die | |||||||
| 3. Technical service | |||||||
| Die vacuum heat treatment and die surface treatment(N-O,C-N,carburize and nitridation surface treatment). | |||||||
