Product Description

DB6 Hot Worked Tool Steel

DB6

1:  DB6 steel introduction

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.

4: DB6 steel mechanical properties

    The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

Application DIN 1.2714 tool steel are suitable for the cutting tool, cold/heat distortion mould and measuring implements, and further to manufacture the piston, valve, valve seat of fuel pump of diesel engine, Cutting tools, Mechanical parts, Air hammer tools, Piercing tools.

6: Heat treatment 

    The preheating of measuring and cutting tool steel is spheroidizing annealing, final heat treatment is quenching + low temperature tempering and hardness after heat treatment can reach 60~65HRC. When heat treat tool steel grades consideration should be given to hardening temperature, including ratio of heating, cooling and soaking times which will differ due to factors such as the shape and size of each chemical component. Other considerations during heat treatment include the type of furnace, quenching medium and work piece transfer facilities.

 

7: Features and classifications 

    Hot-work die divides into several main types, such as hammer forging, die forging, extrusion and die casting, including hot forging die, press machine forging die, stamping die, hot-extrusion die, metal die-casting mould. Heat distortion mould not only supports huge mechanical stress, but also thermal stress during working repeatedly. Hot-work die steel should have not only high hardness, red hardness, abrasion resistance, toughness, but also have excellent high temperature strength, thermal fatigue stability, thermal conductivity, upper harden-ability for guaranteeing the whole cross section with consistent mechanical property.

8: Delivery condition
    For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
    For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.

    For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
