5CrNiMo Steel


5CrNiMo is a hot work die steel. Except its hardenability and thermal fatigue resistance are slightly worse, the steel has similar properties to H13 steel.

Features of 5CrNiMo Steel

  • The steel has good toughness, strength and high wear resistance.

  • Its mechanical properties are almost the same at room temperature and 500~600℃.

  • When heated to 500℃, it still maintains hardness of HB300.

  • It is not sensitive to temper brittleness because of molybdenum content.

  • After slowly cooling down from 600°C, its impact toughness is only slightly reduced.



Application of 5CrNiMo Steel

  • This steel is suitable for making various types of forging dies that require high strength and wear resistance. When higher toughness is required, electroslag remelted steel can be applied.
