5CrNiMoV Tool Steel

Under heavy forging and impact load conditions, the toughness of the die directly determines its service life. 5CrNiMoV, as a representative of high-toughness hot work die steel in the Chinese national standard (GB/T 1299), has solved the industry pain points of easy cracking and short service life of large forging dies through high nickel content and vanadium-molybdenum composite strengthening. Its room-temperature impact energy is ≥40J, and it maintains a stable structure even at working temperatures of 400-500℃, making it the preferred material for automotive crankshafts and forging dies for construction machinery.
