2767 Tool Steel
2767 tool steel stockholders and suppliers, delivering to the whole of the Middle East. Nifty Alloys LLC are suppliers of round bar, diameters and plate. 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.
Typical Analysis
| Carbon | 0.45% | Manganese | 0.40% |
| Nickel | 4.25% | Chromium | 1.30% |
| Molybdenum | 0.25% |
Forging
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.
Annealing
Heat uniformly to 630-650°C. Soak well and cool slowly in the furnace to approximately 600°C then cool in air.
Stress Relieving
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.
Hardening
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.
Tempering
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.
