High-Performance Hot Work Tool Steel

SITHERM 2344 is a versatile hot work tool steel with high hardness, strength, and excellent resistance to thermal fatigue, erosion, and wear. Its robust composition, featuring chromium, molybdenum, and vanadium, makes it ideal for applications requiring high performance at elevated temperatures. Common uses include hot die work, die casting and extrusion dies, wear-resistant tools, and pressure die casting tools. Additionally, it excels in manufacturing pressing tools for both light and heavy metals.

Industries in detail

Product advantages

This alloy is one of the hot work, chromium type tool steels. It also contains molybdenum and vanadium as strengthening agents. The chromium content assists this alloy to resist softening if used at higher temperatures. Secondary hardening steels with good tempering reistance. It maintains high hardness and strength at elevated temperatures. Good resistance to thermal fatigue, erosion and wear. Steel with very high thoughness and good ductilityand hardenability. Tools can be water cooled.
