Uses

Tool and die steel for cutting, forming, punching and molding tools. Tungsten/molybdenum (≈0%/1.3%) give hot hardness and red-hardness for high-speed and hot-work tools. High chromium (≈5.25%) provides wear resistance and secondary hardening. Applied to blanks, punches, extrusion dies, shear blades, plastic-mold and cold-work tooling.

Heat Treatment

Hot-work: preheat 800 °C, austenitize 1020–1080 °C, quench, temper 540–620 °C (multiple) for hot hardness and thermal fatigue resistance.

Precautions

Risk of quench cracking and distortion — use graded preheating, controlled cooling and multiple tempers. Avoid overheating the austenitizing temperature. Machine in the soft annealed condition; allow for dimensional change after heat treatment. Grind with coolant to prevent rehardening cracks.
