Quenching and tempering - tec-scienceTempering Steel. After quenching, your steel will be brittle and hard. Most steel applications require a more ductile material, so your steel must be tempering. By sacrificing some of the hardness, you can create a balance between hard, ductile material. Typically, tempering steel occurs with temperatures between 400 and 1,105 degrees Fahrenheit.
