AISI H11 Steel Round Bar Sheet Plate, DIN 1.2343, JIS SKD6

H11 steel also is called DIN 1.2343 and JIS SKD6 steel. 1.2343 steel is the
air-cooling type hot work mold steel. It is one of the three most commonly used
of hot work mold steel in the European die-casting industry. The carbide is
small and distributed uniformly in steel. H11 tool steel has great cold and
heat fatigue resistance, corrosion resistance, hot and cold processing
performance and hardenability. It has oxidation resistance, high toughness and
wear resistance in the medium temperature.

H11 Steel Round Bar Plate Sheet Heat Treatment
1.Machinability
The machinability rate of 1.2343 tool steels is nearly 75% of that of the W
group tool steels.

2.Forming
1.2343 tool steels are formed by using conventional methods, machining and
forging.

3.Welding
1.2343 tool steels can be readily welded by conventional methods.

4.Heat Treatment
1.2343 tool steels are preheated to 816°C (1500°F). Then the steels are
directly heated by increasing the temperature to 1010°C (1850°F) followed by
holding for 15 to 40 mins. The steels are then air-quenched.

5.Forging
1.2343 tool steels are forged at 1121°C (2050°F). For this type of steels,
forging below 899°C (1650°F) is not preferable.

6.Cold Working
Cold working may be carried out on 1.2343 tool steels using conventional
methods.

7.Annealing
1.2343 tool steels are annealed at 871°C (1600°F) and slowly cooled at 4°C
(40°F) in the furnace.

8.Tempering
Tempering is carried out on 1.2343 tool steels at a temperature ranging from
538 to 649°C (1000 to 1200°F) to obtain Rockwell C hardness of 54 to 38.
Double tempering can also be performed in these steels every one hour at the
preferred tempering temperature.
