1.2343 Steel Characteristics
1.The toughness of 1.2343 steel is higher than H13 steel. It needs to heat treatment. And the hardness of general application is 50-54HRC.
2.Widely used for the insert parts of the mold.
3.High hardness and toughness, meeting many requirements of hot work mold steel.
4.The main components are chromium, molybdenum and vanadium, 1.2343 steel is smelted by the electroslag remelting process.
1.2343 Steel Application
The application is decided by DIN 1.2343 steel chemical composition and properties. Some application of 1.2343 steel as below:
1.Hot punches
2.Forging dies
3.Hot shear blades
4.Hot gripper dies
5.Extrusion tooling
1.2343 tool steel is used for highly stressed structural parts such as aircraft landing gear. And it is suitable for high-speed hammer forging molds. Such as aluminum and magnesium alloy hot forging die, and its hardness always is 42-50HRC. Black metal forging molds, hardness is 40-50HRC. At the situation of hot work die steel with a high risk of cracking, 1.2343 steel is the best choice. The mold useful time that made of 1.2343 steel can be 1.5-3 times that of AISI L6 steel.
