What is Annealing?
Annealing is a heat treatment process that involves heating a material to a specific temperature, holding it at that temperature, and then gradually cooling it to soften the material, relieve internal stresses, and improve ductility. It is commonly applied to metals such as steel, aluminum, copper, brass, and nickel.
The temperature required for annealing varies depending on the material and its hardness, which is measured on the Rockwell B scale. This calculator helps you find the right annealing temperature based on these parameters, streamlining the heat treatment process for your manufacturing or repair needs.

Example Calculation
Let’s look at a sample calculation using the Annealing Temperature Calculator:
- Material Type: Steel
- Hardness: 120 Rockwell B
- Heat Treatment Process: Full Anneal
Step 1: Calculate annealing temperature for steel:
- For Full Anneal, the formula is:
Annealing Temperature = 900 + (0.30 * Hardness)
Substituting the values:900 + (0.30 * 120) = 900 + 36 = 936°C
Result: The optimal annealing temperature for steel with a hardness of 120 Rockwell B is 936°C.
This is just one example—using the calculator with different materials and hardness values will give you customized results for your specific needs.
