Characteristics
Material properties: Due to the high nickel and corresponding carbon content, this material is a very evenly hardening, dimensionally stable steel with high toughness and resistance to impact and compressive stress.
1.2767 is Nickel cold work tool steel. Good hardenability and thougness. Ability for polishing, photoetching and erosion treatment. Application include forging tools, dies of all sort, shapes and sizes, hot forging and pressing tools for steel and metal. Moulds, bushings, piercers, etc.
Application
Mould plates and inserts for the processing of thermo- plastics and thermosets, especially for high gloss polishes, e.g. for transparent melts and components with high surface requirements, mould components with high compressive and flexural stresses, embossing tools and other uses for which the above requirements are needed.
Heat treatment
Hardening:
At 840°C – 870°C. Details can be found in the time-temperature conversion and tempering charts. The most suitable heat treatment for the relevant workpiece should be fixed by the hardening shop. The hardness should be specified by the hardening shop and checked on delivery.
Soft annealing:
620°C – 650°C, approx. 4 h
Stress-relief annealing:
To eliminate residual stresses after coarse machining at approx. 600°C – 650°C, approx. 4 h with slow heating and furnace cooling.
Normal working hardness:50 - 56 HRC
