高温合金的工作温度可达600～1100℃,在高温下具有足够的高温强度和抗氧化能力。近年来在用于制造热工模具方面取得了极其良好的经济效果。例如在水压机锻造时,采用一般模具钢5CrNiMo制造砧子,由于砧子不断承受热应力,当工作时间超过4小时以后,砧子的中间 High temperature alloy working temperature up to 600 ~ 1100 ℃, at high temperatures with sufficient high temperature strength and oxidation resistance. In recent years, extremely good economic results have been achieved in the manufacture of thermal tools. For example, forging in the hydraulic press, the general mold steel 5CrNiMo anvil, the anvils continue to withstand thermal stress, when the working time more than 4 hours later, the middle of the anvil
