2767 Tool Steel


2767 tool steel suppliers and stockholders. 2767 steel is a 4.25% nickel grade available in rounds and flats with delivery to the whole of the UK. This grade is a higher carbon version of the standard 4.25% nickel steel. A good quality tool steel 2767 achieves high impact and compressive strength and is suitable for applications demanding extra wear resistance. With its characteristics of good full hardenability, good polishability and excellent toughness it is widely used for plastic mould applications.

Applications

Typical applications and components produced in 2767 include plastic moulds, cutlery dies, shear blades for heavy gauge material, cutting tools, drawing jaws and highly stressed coining tools.


Carbon 0.45% Manganese 0.40%
Nickel 4.25% Chromium 1.30%
Molybdenum 0.25%

Heat slowly and uniformly to 1050°C. Re heat as necessary and avoid working below 850°C. After forging cool slowly in furnace or thermoinsulating material.


Heat uniformly to 630-650°C. Soak well and cool slowly in the furnace to approximately 600°C then cool in air.


When tools produced in 2767 tool steel are heavily machined, stress relieving is recommended just before finish machining in order to relieve machining strains. Heat to approximately 650°C. Soak well and allow to cool in air.


Pre heat the 2767 tool slowly and uniformly to 650-700°C and thoroughly soak. Continue heating to the final hardening temperature of 840-870°C and allow the component to be heated through. Quench the component in oil or cool in air.


Slowly heat the tool uniformly and thoroughly at the selected tempering temperatures and hold at heat for one hour per 25mm of total thickness but for a minimum of two hours. Cool in air. 2767 tool steel can be hardened by vacuum furnace, gas quench process.

Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each 2767 steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of tool steels.


Select the correct grade of wheel in consultation with the grinding wheel manufacturer. Ensure the grinding wheel is in good condition by means of a suitable dressing tool. Wet grinding is a preferable option using a copious supply of coolant. If dry grinding is resorted to then use a very soft wheel.
