공구강 열처리 데이터

공구강의 노멀라이징, 어닐링, 경화 및 템퍼링

Complete reference for heat-treating temperatures of all major tool steel grades. Search by grade name, toggle between °C and °F, and expand each category group for full specification data. The quench and temper schedule is also published as a standalone table in the hardening and tempering temperature chart, and the overall process sequence is covered in the tool steel heat treatment guide.

  1. (a) Time held at temperature varies from 15 min for small sections to 1 h for large sizes. Cooling is done in still air. Normalizing should not be confused with low-temperature annealing.
  2. (b) The upper limit of ranges should be used for large sections, and the lower limit for smaller sections. Time held at temperature varies from 1 h for light sections to 4 h for heavy sections and large furnace charges of high-alloy steel.
  3. (c) For 0.25 Si type, 183 to 207 HB; for 1.00 Si type, 207 to 229 HB.
  4. (d) Temperature varies with carbon content: 0.60–0.75 C, 815 °C (1500 °F); 0.75–0.90 C, 790 °C (1450 °F); 0.90–1.10 C, 870 °C (1600 °F); 1.10–1.40 C, 870–925 °C (1600–1700 °F).
  5. (e) Temperature varies with carbon content: 0.60–0.90 C, 740–790 °C (1360–1450 °F); 0.90–1.40 C, 760–790 °C (1400–1450 °F).

  5. (e) Times apply to open furnace heat treatment. For pack hardening, a common rule is to heat 1.2 min per mm (30 min per in.) of cross section of the pack.
  6. (f) Preferable for large tools to minimize decarburization.
  7. (g) Carburizing temperature.
  8. (h) After carburizing.
  9. (i) Carburized per case hardness.
  10. (j) P21 is a precipitation-hardening steel having a thermal treatment that involves solution treating and aging rather than hardening and tempering.
  11. (k) Recommended for large tools and tools with intricate sections.
