2) H13钢的国内牌号为4Cr5M0SiVl,现在正在向低Si高M0方向发展。
3) H13钢的表面改性主要有铁素体氮碳共渗或者硫氮碳共渗以及物理气相沉积硬膜等方法, 更为优越的办法是这些方法进行合理组合。
Surface Modification for Die Casting Moulds of H13 Steel
Abstract: This paper deals with the chemical composition of H13 steel and its improvement of approaching lower silicon and higher molybdenum. Then,it discusses the surface modification for these die casting moulds with PVD processing.
