Performance under Extreme Heat

Advanced Solutions for Hot Work Applications.

Hot work applications involve manufacturing processes where tools operate at elevated temperatures—typically above 200°C—and are exposed to repeated thermal cycling and mechanical stress.

These environments require tool steels with:

High hot strength and hardness retention
Excellent thermal shock resistance
Superior wear resistance
Outstanding toughness at elevated temperatures

Key Industries & Sub-Applications

High Pressure Die Casting

Precision tools used in aluminum and magnesium casting demand high thermal conductivity and resistance to heat checking.

Metal Extrusion

Extrusion dies must withstand continuous heat exposure and mechanical stress, ensuring dimensional stability and long service life.

Forging Solutions

Forging tools operate under extreme loads and temperatures, requiring maximum toughness and resistance to cracking.

Hot Stamping

Hot stamping processes require steels with high compressive strength and thermal fatigue resistance.

Why Hot Work Tool Steels Perform Under Extreme Heat

Hot work tool steels are specifically engineered to maintain mechanical properties even under fluctuating thermal conditions.

Key advantages include:

Resistance to thermal fatigue and cracking
High wear resistance in contact with hot materials
Long and predictable tool life
Reduced cost per produced part

Advanced remelting technologies such as P-ESR and VAR ensure high purity and homogeneity, which are essential for superior performance and reliability.
