Tool steel red hardness
Web9. jan 2013 · Carbides contribute to strengthening of tool steels in two different ways: 1. Carbides provide resistance to (abrasive) wear given that alloy carbides are significantly harder than the matrix material. 2. Carbides contribute to higher yield strengths by impeding the mobility of matrix dislocations.
