Hot work
Hot work tool steels are characterized by excellent thermal conductivity and resistance to oxidation, reducing heat buildup and extending tool life in harsh industrial environments. They also exhibit low distortion during heat treatment, enabling the production of complex, high-precision dies and tools with tight tolerances. Key grades include 1.2343,1.2344, 1.2345,1.2714, H13, H11, H21, and H23, each formulated with precise additions of chromium, molybdenum, vanadium, and tungsten to enhance heat resistance and hardenability.
