If you are interested in our 2767 Mould Steel, please get in touch for more details.
An air or oil hardening die steel of great strength and toughness. 2767 hardens uniformly through comparatively large masses and so with the ability to take a good polish the steel finds wide application as a steel for plastic moulding. The high strength of the steel also enables it to be used in a variety of engineering applications.
Plastic moulding dies, zinc diecasting dies, extrusion die holders and press components, engineering components requiring high strength.
Heat slowly to 630°C / 650°C, soak thoroughly for six hours and furnace cool. The usual annealed hardness is up to 285 HB.
Heat to 650°C / 750°C. Hold for 2-4 hours and furnace cool.
Before heat treatment, sufficient machining should be carried out to remove surface decarburisation. Preheat thoroughly to 650°C / 700°C, and then raise more rapidly to 830°C / 850°C in a controlled atmosphere furnace or preferably, a neutral salt bath. Air cool or quench in oil, the latter being advised for large masses when maximum hardness is required.
Heat to the required temperature for a minimum of one hour and then air cool. A hot air circulation furnace may be used.
