Product Information
Applications:
1.2344 steel is an air hardening, 5% chromium die steel, which is an excellent choice for a wide range of hot work and cold work applications. Typical applications include die casting dies for aluminium, magnesium and zinc, extrusion dies for aluminium and brass, liners, mandrels, pressure pads, followers, bolsters, die cases, die holders and adaptor rings for copper and brass extrusion. H13 steel is used to produce hot stamping and press forge dies, split hot heading dies, gripper dies, hot punching, piercing and trimming tools. Other applications include plastic moulds, shear blades for hot work and hot swaging dies.
General Properties:
1.2344Steel is characterized by
Good resistance to abrasion at both low and high temperatures.
High level of toughness and ductility Uniform and high level of machinability and polishability.
Good high-temperature strength and resistance to thermal fatigue.
Excellent through-hardening properties.
Very limited distortion during hardening.
Good machinability.

Welding:
in general, we do not advise the welding of tool steel but users sometimes prefer to weld in order to avoid the cost of retooling. It should be remembered that this grade is an air hardening steel and that in welding the area of the weld attains a temperature of about 1000°C. Cracking is likely to occur during cooling unless proper precautions are taken. Popular methods of welding are atomic hydrogen and argon arc. We recommend you contact your welding consumables supplier who should provide you full assistance and information on welding tool steels.
Welding Procedure
It is desirable to anneal the tool prior to welding but with care welding may be done on hardened and tempered tools.
It is important to preheat the die to 300-500°C and to maintain this temperature during welding.
after the weld has been completed, maintain at 300-500°C for one hour, then cool the die slowly in a furnace or in insulating material.
If the tool has been annealed prior to welding, stress relieve at 700°C before re-hardening.
If the tool has not been annealed prior to welding, re-temper at 550-600°C for a minimum of 2 hours.
Final Grinding:
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.
