Grade Brief
DB6 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.
DB6 Steel is a tool steel grade that comes under the DIN EN ISO 4957 standard. Due to its excellent combination of wear resistance, additional toughness, and high hardness which are attained using Cr-Ni-Mo-V high graded alloys, DB6 Steel is highly recommended for Close Die Forgings. Therefore, DB6 Steel is the material of choice in the automotive, aerospace, metalworking, and tool and die sectors. We provide die blocks as an additional forging reduction and upsetting step with double tempering to improve ultrasonic quality.
