135-2435- 1833
Implementation standard: GB/T 1299- 1985, which is hot-working die steel. The properties of 5CrNiMo steel are similar to those of H 13 steel except that the hardenability and thermal fatigue resistance are slightly poor, but the hardenability is slightly poor. This steel is suitable for manufacturing various types of forging dies that require high strength and high wear resistance. It is required when the toughness is high.
