Allowances of steel die forging 公差及机械加工余量
The high temperature wear property of a new type precision cast hot-forging die steel was studied, and compared with that of H13 steel. The mechanism of the high temperature wear was discussed.
研究了新型精铸热锻模具钢的高温磨损性能，并与H13钢进行对比探讨高温磨损机理。
Compared with the forging die steel, casting forging die steel although toughness is low, but high strength, red hardness is good, with low notch sensitivity and high resistance to thermal fatigue.
与锻造模具钢相比，铸造热锻模具钢虽然韧性低，但强度高、红硬性好，具有较低的缺口敏感性和较高的抗热疲劳性。
Hot die forging, in addition to the hot work die steel casting, the wear and heat load large front steel casting mold is often used.
热作模具锻造中，除上述热作压铸模具钢外，磨耗及热负荷大的模具常采用铸型锋钢。
