Tool steel selection - Practical Machinist

Mar 15, 2012 · Because they are air-hardening alloys, Group A tool steels exhibit minimum distortion and the lowest tendency to crack during hardening. Manganese, chromium, and molybdenum are the principal alloying elements. Types A2, A3, and A7, A8, and A9 contain 5% chromium. Typical applications include shear knives, punches, forming dies, and coining dies.
