What is BS4659 BH13 Tool Steel?

BS4659 BH13 is a chromium-molybdenum-vanadium alloyed hot work tool steel designed for high temperatures, significant pressure, and cyclic thermal stress. It excels at resisting thermal shock, preventing cracking during rapid heating and cooling cycles — making it ideal for aluminum die casting, metal extrusion, and drop forging dies.

A key characteristic of BH13 is its ability to maintain uniform hardness and strength at elevated temperatures, ensuring tools retain their shape and cutting edge over time. It also offers good machinability in its annealed state, allowing precise fabrication of complex tool geometries. BS4659 BH13 is a proven material with a long history of reliability in extreme industrial environments.
