1.2344 tool steel has a very fine grain size, which contributes to its excellent toughness and resistance to thermal fatigue.The addition of vanadium in 1.2344 tool steel helps to refine the grain structure and improve its overall performance, including its resistance to wear and deformation.

1.2344 tool steel has a high chromium content, which contributes to its excellent resistance to corrosion and oxidation at high temperatures.It is often used in the manufacturing of large and complex dies and tools, such as die-casting dies, hot forging dies, and plastic injection molding tools, due to its excellent thermal conductivity and resistance to thermal fatigue and is widely used in the automotive and aerospace industries, as well as in other high-temperature applications that require high strength, toughness, and resistance to wear and deformation.

1.2344 tool steel can be processed by both conventional and advanced manufacturing techniques, such as hot forging, hot rolling, and powder metallurgy, which allows for greater flexibility in tool and die design.The properties of 1.2344 tool steel can be further enhanced by the use of advanced surface treatments, such as nitriding or coating, which can improve its wear resistance and extend its service life.
