5CrNiMo钢具有良好的韧性、强度和高耐磨性,属热作模具钢。它在室温和500~600℃时的力学性能几乎相同。在加热到500℃时,仍能保持住HB300左右的硬度。由于钢中含有钼,因而对回火脆性并不敏感。从600℃缓慢冷却下来以后,冲击韧性仅稍有降低。

5CrNiMo steel has good toughness, strength and high wear resistance, and is a hot work die steel. It has almost the same mechanical properties at room temperature and 500 to 600 °C. When heated to 500 ° C, it can still maintain the hardness of HB300. Because steel contains molybdenum, it is not sensitive to temper brittleness. After slowly cooling from 600 ° C, the impact toughness was only slightly reduced.
