Unless you have worked in the manufacturing industry, there is a good chance that you have little or no knowledge of the thermal processes used to strengthen ferrous metals. However, these processes have had an impact on your life. This is because, without the use of thermal processing, you would not have access to products such as the steel springs inside your couch or bed, high end cookware, or even steel support beams for your home. Below, you will learn more about how thermal processing makes these products possible and how you can use your newfound knowledge of thermal processes to help you choose the very best products the market has to offer.
How Thermal Processing Changes Metals
Thermal processing is a heat application in which ferrous metals, such as steel, are brought to a very specific temperature and then allowed to dry in still air. The hotter the metal gets, the softer it will become. Consequently, these materials will be heated to a higher temperature when trying to create flexible products, such as springs, and heated to a lower temperature when created harder products, such as support beams. If it was not for the ability to affect the hardness of these metals, it would be simply impossible to use these materials to create many of the most popular products on the market today.
Spotting Evidence Of Thermal Processing
When metal is heated, the light index which it reflects will change. This is why you will sometimes see a frying pan that reflects blue light, while another one will reflect a golden hue. This is a result of the thermal process used to create the product and can give you important information about the temperature that the metal was heated to. Remembering that the higher the temperature used in the thermal process, the softer the metal is, this information can ultimately be used to help you choose high quality products when shopping for your home.
Using the example above, a frying pan that reflects a blue hue will indicate that it has been heated to a higher temperature than one that reflects a golden hue. Since the goal when shopping for cookware is to select a product that is hard enough to stand up to the test of time and frequent use, it is always better to buy the product that reflects a golden light. This same approach can be used when purchasing metal furnishings or even metal building materials for a home improvement project.
