Product Features & Applications

Ultra-clean Structure by ESR Remelting

2344ES provides superior purity, uniform carbide distribution, and reduced impurity levels for higher toughness and crack resistance.

Exceptional Thermal Fatigue Resistance

Performs reliably under repeated heating and cooling cycles, ideal for die casting and high-temperature hot work tooling.

High Toughness & Impact Strength

Resists chipping and cracking in molds subjected to strong mechanical load and thermal shock.

Stable Hardness at Elevated Temperatures

Maintains excellent wear resistance and strength during continuous hot work operations.

Wide Range of High-temperature Applications

Perfect for aluminum die casting dies, extrusion tooling, hot forging dies, high-temperature injection molds, and other hot work environments.

Product Details

2344ES is produced through vacuum degassing + ESR remelting + controlled forging, resulting in a highly homogeneous microstructure with low sulfur and phosphorus content.

After vacuum quenching and precision tempering, 2344ES exhibits stable hardness, strong toughness, superior thermal fatigue resistance, and excellent heat crack resistance.

Thanks to its durability and predictable performance, 2344ES is widely used in high-output die casting operations, precision forging dies, and demanding hot work tools requiring long service life and minimum downtime.
