If you are looking for high-quality DB6 tool steel, you might be interested in learning more about its properties, applications and equivalent grades. In this blog post, we will provide you with some useful information about this hot work tool steel that is widely used for close die forgings.
DB6 Steel Properties
DB6 steel, also known as DIN 1.2714 or AISI L6, is a pre-hardened tool steel with high wear-resistance, extra toughness and high hardness. It is achieved with Cr-Ni-Mo-V high graded alloys that make it suitable for hot work applications. The standard hardness of DB6 steel is 360 to 430 BHN, but it can be tempered to different levels depending on the desired performance.
Some of the main properties of DB6 steel are:
- Chemical Composition: C 0.50-0.60%, Si 0.10-0.40%, Mn 0.65-0.95%, P <0.015%, S <0.004%, Cr 1.0-1.20%, Ni 1.50-1.80%, Mo 0.45-0.55%, V 0.07-0.12%
- Mechanical Properties: Tensile strength 1000-1400 MPa, Yield strength 1045 MPa, Elongation 15%-20%, Impact toughness 20-25 J/cm2, Hardness 50-55 HRC
- Physical Properties: Coefficient of thermal expansion 12.1-14.3 x 10^-6 m/(mK), Thermal conductivity 35.0-39.0 W/(mK)
Equivalent Grades:
DB6 steel is equivalent to DIN 2714, AISI L6, AFNOR 55NCDVV7, JIS SKT4 and other international standards. These grades have similar chemical composition and mechanical properties, but may differ in some aspects such as heat treatment, applications and availability.
Applications:
DB6 steel is mainly used for manufacturing dies of various types, such as press dies, extrusion dies, die moulds, shoe blocks, die holders, piston rods, bolsters, cranks, cassettes, plastic moulds, shearing blades, tools and more. It is especially suitable for close die forgings due to its high impact resistance and toughness.
