Altering the properties of a metal requires the use of heat, or the removal of heat utilizing a quenching technique. Treating metal with heat, or cooling it after it is heated, can alter the next properties to various degrees: ductility, hardness, softness, stress, and tensile strength. To achieve one or more of these properties, a number of of the following treatments may be used: annealing, tempering, hardening, quenching, normalizing, and stress relieving. An overview of every treatment is listed below: Annealing Annealing removes stresses or induces softness to boost ductility or formability, respectively. Common types of annealing include: Bright annealing- Bright annealing is conducted in a vacuum furnace, bell annealer, or controlled atmosphere furnace to prevent oxidation. It really is typically performed on chromium alloys such as for example stainless steel. Process annealing- Process annealing makes metal simpler to cold roll or draw. Click here for more info can also make it more formable for bending applications. Recovery annealing- Recovery annealing restores ductility and reduces stresses in cold worked metal. Full annealing- Full annealing produces the softest, most stress-free metal. It really is typically performed to make metal better to machine, or to improve its dimensional stability. Annealing occurs in a temperature range of 300�F – 2250�F. Tempering Tempering reduces stresses and unwanted hardness caused by quenching. It is often performed after quenching that follows brazing or annealing. The tempering process takes place in a temperature range of 350�F – 1250�F. Hardening Hardening is a heating treating process that improves the mechanical properties and hardness of metals. It really is typically performed by means of “quenching.” Common hardening methods include: Water quenching- Water quenching improves the strength and hardness of low and medium carbon steel. Oil quenching- Oil quenching improves the strength and hardness of medium and high carbon steel. Air quenching- Air quenching improves the strength and hardness of low and medium carbon steel while reducing the risk of distortion. Age hardening- Age hardening is performed on alloys that harden because of age or the current presence of precipitation. Hardening takes place in a temperature range of 300�F – 2250�F. Normalizing Normalizing is conducted on ferrous metals to improve their mechanical properties, or even to improve their reaction to the hardening process. Normalizing occurs in a temperature range of 1600�F – 1800�F. Stress Relieving Stress relieving relieves stresses in metal to boost dimensional stability and tensile strength. Common examples of stress inducers include: flame cutting, cold working, quenching, and welding fabrication. check here relieving process occurs in a temperature selection of 300�F – 1400�F. Conclusion The list above is a basic overview of heat treating processes provided by professional metal treatment services. When a company needs to alter the properties of metal pieces or assemblies, having them treated with these processes can bring remarkable cost savings compared to buying new components.
