Hot work tool steels
Technical data sheets for hot work tool steel grades
Overview
Hot work tool steels are a particular category of tool steels. They are used for making work parts which are employed in the temperature range from 450°C to 600°C, but also fluctuating termic loads. Hot work steels are used for die-casting molds of light alloys, liners, mandrels and other parts for extrusion presses, hot shear blades, equipment for the production of bolts. In this steel family we find the brands 2714, 2365, 2343 and 2344. Tool steels for hot work must be able to withstand not only mechanical and abrasive stresses but also have a high tempering resistance.
