DIN 1.2714 is highly recommendable for Close Die Forgings due to its characteristics of high wear-resistance, extra toughness , high hardness which is achieved with Cr-Ni-Mo-V high graded alloys.
The equivalent grade DB6 / L6 / SKT4 normally used as a pre hardened condition. The standard hardness is 360 to 430 BHN. DIN 2714 is the upgraded version of DIN 2713 for better performance of dies.
We supply Die blocks as the extra Forging Reduction & Upsetting with Double tempered to achieve the better Ultrasonic quality.
The special Hot Work Pre hardened Steel with good toughness and high ware resistance. Die Steel is normally supply in hard, quenched & tempered and also in annealed condition in special case. Usually its working hardness is 360-430 BHN. This steel grade is the upgrade version of DIN 2713 for better performance.
