Web28 aug. 2024 · How to “Thermal Cycle” in a Furnace. 1) Normalize by heating to the recommended temperature for 10-15 minutes and air cool. 2) Anneal by heating to the recommended temperature for 15-30 minutes, cool at 600°F/hr (300°C/hr) to 1100°F. After 1100°F the steel can be furnace cooled or air cooled it doesn’t matter. WebTempering is a heat treating method to reduce brittleness and to increase strength of the metal. Some materials like iron-based alloys are very hard and therefore very brittle. When tempered, these metals are heated to a temperature lower than the critical point. This reduces brittleness and maintains hardness. 2.
