PSM Industries Ferro-TiC® CHW-25 Hot Work Tool Steel Product Information -:- For detailed product information, please contact sales. -: # **PSM Industries Ferro-TiC® CHW-45 | Hot Work Tool Steel Metal Matrix Composite** ## **Overview** PSM Industries' Ferro-TiC® CHW-45 represents a groundbreaking advancement in high-temperature tooling materials, specifically engineered to withstand the extreme demands of hot work applications. This innovative metal matrix composite (MMC) combines a sophisticated hot work tool steel matrix (based on H13/1.2344 chemistry) with a strategically optimized volume of titanium carbide (TiC) reinforcement. Utilizing proprietary powder metallurgy and advanced consolidation technologies, the CHW-45 grade delivers a unique combination of **exceptional thermal fatigue resistance, retained hot hardness, and superior wear resistance at elevated temperatures** – a combination unattainable with conventional tool steels or monolithic carbides. It is specifically designed for hot forming, die casting, and forging applications where thermal cycling, abrasive wear, and heat checking are primary failure mechanisms. ## **Key Features:** - **Optimized for Hot Work:** Specifically engineered matrix chemistry and carbide distribution for sustained performance at 500-650°C (930-1200°F) - **Superior Thermal Fatigue Resistance:** Exceptional resistance to heat checking and thermal cracking under cyclic heating/cooling conditions - **Excellent Hot Hardness:** Maintains significantly higher hardness at elevated temperatures compared to conventional H13 and similar hot work steels - **Enhanced Wear Resistance at Temperature:** TiC reinforcement provides outstanding abrasion resistance even when the steel matrix softens - **Improved Thermal Conductivity:** Optimized microstructure facilitates better heat extraction, reducing thermal gradients in tooling - **Reduced Tendency for Soldering/Galling:** Superior surface characteristics minimize adhesion of molten metals in die casting applications - **Isotropic Properties:** Uniform PM structure ensures consistent performance regardless of orientation --- ## **Material Specifications: Ferro-TiC® CHW-45** ### **1.
