摘要
３Ｃｒ２Ｗ８Ｖ钢热锻模采用调质预处理＋高温真空淬火新工艺，可提高模具的高温硬度和强度、耐磨性及抗热疲劳性，使模具使用寿命提高２～３倍，并防止模具的早期失效．
New technology of the previous quenching and tempering then quenched in a high temperature and the vacuum is applied to hot forging dies of the 3Cr 2W 8V steel.It increases the hardness,strength,wearing-resistance and heat fatigue-resistance in a high temperature. It makes the life of the forging dies to increase 2～3times and prevent their failure at the early stage.
