Hot Work Steel 2344

Main Characteristic

2344 classified as a hot work steel in the class of Cr-Mo-V. It is widespread used in various industry.
Suitable for hot work mold in every categoris, steel, plastic, glass. Moreover, it also well known for
making of cutting tool for thicker gauge steel. To be part of mold and tooling. Thanks to its suitable
chemical composition from 0.4 carbon which help enhance strength whilst hardening at high temperature.
Content of Chromium 5 % benefit in standing for high temperature during work. Also, hardening with air is
possible and give good deed for maintaining it's size/dimension tolerance. Silicon 1.0% help resistance
of oxide at high temp. Molybdinum and vanadium help maintain its strength at high temp. Specially
on Vanadium result in high abrasive resistance. With our special production blend, the grain size is so
small that the structure is homogenize with precision, this help benefit in high strength and tensile
during its work load.

OutStanding Properties

   Resistance for changing of temperature during usage
   maintain its strength among differ temperature.
   Resistance to fatigue due to high temperature
   High strength
   Resistance to wear and tear
   Easy to hardening , less in changing of its size/ dimension
   High properties of heat transferring
   Resistance on sharp turning of temperature.
   Can do direct cooling by water
   Can do nitriding to enhance surface hardness


2344 can apply for high temp task in various industry such as, injection steel mold, forging,
pressurized mold, Glass/plastic injection mold, Screw and cylinder for injection of steel/plastic.
Hot cutting tool.
