Applications

Typical applications include medium run dies, press tools, drawing punches, broaches, bushings, lathe centres, chuck jaws, master cavity sinking hobs, plug gauges, thread gauges, thread cutting tools and precision measuring tools. It is also a popular tool steel for cams, cloth cutting knives, cold taps, reamers, collets, tube expander rolls, plastic moulds and woodworking knives, cutting hobs, strip slitting cutters and trimmer dies.

Carbon 0.85-0.95% Chromium 0.20-0.50%
Manganese 1.80-2.20% Silicon 0.10-0.40%
Sulphur 0.03% max Vanadium 0.05-0.20%
Phosphorous 0.03% max

Heat the tool steel slowly and uniformly to 1000°C. Forge within a range of 1050-850°C reheating if necessary. Cool slowly (preferably in a furnace) to avoid setting up stresses.

Heat uniformly to 720°C, equalise, then furnace cool. (Hardness about 229 Brinell). Fully machined tools in grade 1.2842 should be packed during annealing.

Heat the 1.2842 uniformly to 790-820°C until heated through. (If possible pre-heat at 300-500°C). Allow 30 minutes per 25 millimetre of ruling section and quench immediately in oil.

Martempering of 1.2842 is an alternative hardening procedure which may be used when suitable salt bath equipment is available.

Heat the steel uniformly and thoroughly at the selected tempering temperatures and hold for at least one hour per 25mm of total thickness.

Temperature [°C] 100 150 200 250 300 400
Hardness [HRc] 64 63 62 60 56 50

Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the size and shape of each 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.
