Quenching and tempering tec science

Depending on whether a high hardness (“hardening”) or strength/toughness (“strengthening”) has to be achieved, the final process, the so called tempering, is carried out at different temperatures. When a steel has to become very hard, it is only tempered at relatively low temperatures in the range of 200 °C to 400 °C, while it becomes tougher and high load capacity at higher temperatures (in the range of 550 °C to

Speedy Metals Information for A2 Tool Steel Plate

Preheat slowly to 1350 1450°F and hold at this temperature until part is uniformly heated. After thorough preheating, heat to 1750 1800°F. Hold the workpiece at the hardening temperature until it is completely and uniformly heated. A2 is an air hardening steel and will develop full hardness on cooling in still air.

Hardening and tempering of knife steel — Sandvik

Purpose of hardening and tempering of knife steel. Hardening is a way of making the knife steel harder. By first heating the knife steel to between 1050 and 1090°C (1922 and 1994°F) and then quickly cooling (quenching) it, the knife steel will become much harder, but also more brittle.
