AISI H-13 / DIN 1.2344

AISI H-13, also known as DIN 1.2344, is one of the most widely used tool steels in various industries due to its exceptional performance in hot work applications. This high alloyed chromium-molybdenum-vanadium steel is well-known for its outstanding wear resistance to thermal shock and heat cracking, as well as its strong mechanical properties and toughness in hot working conditions. H-13 is recognized for its excellent machinability and ability to maintain consistent hardness during production.

H-13 is a versatile tool steel, combining chromium, molybdenum, and vanadium, making it ideal for both hot work and cold work tooling applications. Its hot hardness allows it to resist thermal fatigue cracking (also known as heat checking), which is caused by repeated cycles of heating and cooling during hot work processes. Due to its unique combination of toughness and resistance to thermal fatigue, H-13 is commonly used in hot work tooling applications more than any other steel.

Steel Properties

AISI H-13 offers exceptional hot wear resistance, high hot tensile strength, and excellent toughness. Its thermal conductivity and resistance to thermal cracking make it ideal for use in hot working processes. H-13 is also resistant to damage from thermal shock, and it can be water-cooled to a limited extent without losing its properties. These qualities make it one of the best tool steels for maintaining performance under high-temperature conditions.

Application

AISI H-13 is extensively used in the production of dies for drop forging, aluminum and low-pressure die casting, and extrusion processes. It is also employed in a wide range of other hot work applications, including containers, liners, punches, plugs, holders, and injection molds. Its durability and resistance to wear and heat cracking make it a go-to choice for tooling that operates under high temperatures.
