Influence of Heat Treatment on Microstructure and Mechanical Properties of Cr8Mo2SiV Cold Work Die Steel: A Comparison with Cr12MoV Steel

Abstract:

Microstructure and mechanical properties of a new developed cold work die steel (SDC99) were investigated under solution treatment and comparison with Cr12MoV steel. The new developed high strength and high toughness cold work die steel has overcome the weakness of Cr12MoV which failed with tipping, fracture and collapse in services due to low toughness. The toughness achieves to 80J which is twice as Cr12MoV while the hardness is 62HRC.
