- within 30-45days
- 5000 Ton/Tons per month
1.2344 has good comprehensive performance at medium temperature (~600°), high hardenability (that can be hardened in the air), low heat treatment deformation rate, and its performance and service life are higher than 1.2581
1.2344can be used for forging hammer forging dies, aluminum alloy die-casting dies, hot extrusion dies, high-speed precision forging dies and forging press dies, etc.

Main features
1.2344 steel is the most widely used and representative hot work die steel. Its main characteristics are:
(1) It has high hardenability and high toughness;
(2) Excellent resistance to thermal cracking, and can be water-cooled in the workplace;
(3) With moderate wear resistance, carburizing or nitriding can also be used to increase the surface hardness, but the thermal crack resistance should be slightly reduced;
(4) Because of its low carbon content, the secondary hardening ability during tempering is poor;
(5) It has the ability to resist softening at higher temperatures, but the use temperature is higher than 540°C (1000°F) and the hardness drops rapidly (that is, the capable working temperature is 540°C);
(6) The deformation of heat treatment is small;
(7) Medium and high machinability;
(8) Medium resistance to decarburization.
What is more noticeable is that it can also be used to make important components in the aviation industry.
Life purpose
The use is basically the same as 1.2510 die steel, but because of its higher vanadium content, the medium temperature (600 degrees) performance is better than 1.2343 steel. It is a representative steel grade with a wide range of uses in hot work die steel.
H13 die steel is used to manufacture forging dies with high impact load, hot extrusion dies, precision forging dies; die-casting dies for aluminum, copper and their alloys.
