PSM Industries Ferro-TiC® SK Impact Resistant Tool Steel Product Information -:- For detailed product information, please contact sales. -: # **PSM Industries Ferro-TiC® SK | Impact-Resistant Tool Steel Metal Matrix Composite** ## **Overview** PSM Industries' Ferro-TiC® SK is a revolutionary impact-resistant metal matrix composite engineered specifically for applications demanding exceptional toughness alongside superior wear resistance. Representing a significant breakthrough in tool steel technology, this material uniquely combines a shock-resistant tool steel matrix (based on S7/1.2357 chemistry) with a strategically controlled dispersion of titanium carbide (TiC) particles. Manufactured through proprietary powder metallurgy processes, Ferro-TiC® SK achieves what was previously considered impossible: **maintaining the high impact toughness of premium shock steels while dramatically improving wear resistance through TiC reinforcement**. It is specifically designed for demanding tooling applications where brittle fracture, chipping, or catastrophic failure under impact loading are primary concerns, while still requiring extended wear life. ## **Key Features:** - **Unprecedented Toughness-Wear Balance:** Engineered to provide significantly higher wear resistance than conventional shock steels while maintaining impact toughness far superior to standard Ferro-TiC® grades - **Optimized for Impact Loading:** Specifically designed matrix chemistry and carbide distribution to absorb energy and resist crack propagation under shock conditions - **Enhanced Fatigue Resistance:** Superior resistance to fatigue failure under cyclic impact loading compared to both conventional tool steels and cemented carbides - **Excellent Machinability:** Maintains good machinability in the annealed state despite TiC reinforcement - **Dimensional Stability:** Minimal distortion during heat treatment enables production of precision components - **Isotropic Properties:** Uniform PM microstructure ensures consistent performance regardless of load direction - **Broad Hardness Range:** Can be heat treated to various hardness levels to optimize toughness or wear resistance for specific applications --- ## **Material Specifications: Ferro-TiC® SK** ### **1. Chemical Composition (Typical, wt%)** The SK composition is carefully engineered to maximize toughness while providing adequate wear resistance through controlled TiC reinforcement: | Element | Content Range (wt%) | Function & Notes | |---------|---------------------|------------------| | **Iron (Fe)** | Balance | Matrix base metal | | **Titanium (Ti)** | 4 - 8% | Forms TiC reinforcement (lower volume than wear grades) | | **Carbon (C)** | 0.8 - 1.2% | Balanced for matrix properties and carbide formation | | **Chromium (Cr)** | 3.0 - 3.5% | Provides hardenability and mild corrosion resistance | | **Molybdenum (Mo)** | 1.3 - 1.8% | Enhances toughness and hardenability | | **Silicon (Si)** | 0.2 - 0.5% | Deoxidizer and strengthening element | | **Manganese (Mn)** | 0.2 - 0.5% | Improves hardenability and strength | | **Vanadium (V)** | 0.1 - 0.3% | Optional addition for grain refinement | *Note: The "SK" designation indicates Shock/Impact grade. TiC volume fraction is approximately 15-25% by volume – intentionally lower than wear-focused grades to preserve toughness. The matrix is specifically designed for high impact energy absorption.* ### **2.
