Heat Treatment
1) Forging
Preheat slowly to 750°C then increase temperature more rapidly to 1050-1100°C. Do not forge below 850°C. It is essential to cool slowly after forging, either in a furnace or in vermiculite.
 
2)Annealing
Soak thoroughly at 840-860°C before furnace cooling at a maximum rate of 20°C per hour down to 600°C
followed by cooling in air. To avoid scaling, box annealing in cast iron chips is preferred.
 
3)Stress Relieving
When tools made from 1.2344 tool steel are heavily machined or ground, the relief of internal strains is advisable before hardening to minimise the possibility of distortion. Stress relieving of this grade of steel should be done after rough machining. To stress relieve, heat the component carefully to 700°C, allow a good soaking period (two hours per 25mm of section). Cool in the furnace or in air. Tools may then be finish machined before hardening.
 
4)Hardening
Preheat to 780-820°C. Soak thoroughly, then increase rapidly to the hardening temperature of 1000-1030°C. When it has attained this temperature, soak for 20 to 30 minutes. Cool in air. Large sections may be quenched in oil. To reduce scaling or decarburisation, we recommend isothermal molten salt bath treatment. Preheat in salt at 780-820°C then transfer to salt bath standing at 1000-1030°C. Soak and quench into salt standing at 500-550°C. Allow to equalise, withdraw and cool in air. Alternatively, 1.2344 tool steel may be vacuum hardened or pack hardened. Tools should be tempered as soon as they become hand-warm.
 
5)Tempering
Heat uniformly to the required temperature allowing a soaking time of two hours per 25mm of ruling section. Withdraw from the furnace and allow to cool in air. A second tempering is strongly advised, the tool being allowed to cool to room temperature between tempers. The usual tempering range is 530-650°C depending on the hardness requirements and the operating temperature of the tool.
 
6)Nitriding
1.2080 tool steel can be nitrided to give a hard surface case. The steel is then very resistant to wear and erosion. Nitriding also increases resistance to corrosion. Nitriding in ammoniac gas at a temperature of 525°C will give a surface hardness approximately 1000 to 1250HV. Before nitriding the tool should be hardened and tempered at approximately 50°C above the nitriding temperature. It is important to note that with increase in penetration of the nitriding, there is a reduction in resistance to thermal shock and an increase in embrittlement.
 
Charateristics
After heat treatment the tool steel is hard, durable, dense, and is immune from sinking in use. It offers a measure of corrosion resistance when polished. In general, the applications of 1.2080 tool steel resemble those of 1.2379 but it should be remembered that 1.2080 has better wear resistance of the two steels and is preferred for such items as shear blades. Owing to its higher wear resistance, 1.2080 tool steel is slightly more difficult to grind than 1.2379.
 
Applications
As a quality tool steel 1.2080 is suitable for applications such as complex blanking and forming tools for long runs and for hard and abrasive materials. It is commonly used for other applications such as brick and tile mould liners, master hobs for cold hobbing plastic moulds, tabletting punches and sleeves for corrosive powders.
