Material 1.2714

pecial alloys for toolmaking: Hot work tool steel | Properties of material 1.2714

Toolmakers manufacture instruments for the production of objects from a wide variety of materials. In order to succeed in giving these materials a shape, the tool must be harder than the starting material to be machined at the respective working temperature. The working temperature is a decisive criterion. It influences the hardness of the tool steels. For the above reason, we distinguish cold work steel and hot work steel.

Characteristics of hot work tool steel & special properties of material 1.2714

The hardness values of hot work steels do not reach those of cold work tool steels. This is due to the fact that the metals to be processed are equally softer in the hot state. In line with this, the carbon content of hot work tool steel is lower and in the majority of cases ranges between 0.25 and 0.55%. Material 1.2714 has a carbon content of 0.55%.
Hot work tool steel is mainly quenched and tempered to around 40-50 HRC. Important alloying elements for this type of tool steel are chromium, molybdenum, vanadium and tungsten. They make a hot work tool steel more temper-resistant.
Material 1.2714 is a tough die steel with high tempering resistance and through hardening. In the round steel sector, it is generally supplied annealed or quenched and tempered to an installation hardness of 370-410 HB.
In the square and flat steel range annealed, respectively with a hardness of 355-400 HB.
This tool steel is suitable for the manufacture of all types of forging dies, die holders, armored cutting plates and hot shear blades.

Physical properties of material 1.2714

According to the material data sheet, the coefficient of thermal expansion 10 to the power of 6 m/(m x K) as a function of temperature ranges from 12.2 (temperature range 20-100 °C) to 14.4 (temperature between 20 °C and 600 °C).

2 The thermal conductivity W/(m x K) stated in the material data sheet is as follows:

20 °C: 36,0
350 °C: 38,0
700 °C: 35,0
