It is said to achieve the best possible quality for your finished product begins with the pre-machining microstructure of your material. Steel (Bars and tubular products as CRS, HRS… etc., casting, forging)

With castings, it is important to understand the chemistry of the steel at hand. Variation of normalizing temperature may be necessary.

It is important to understand that while most ferrous material can be normalized, not all are or can be. The manufacturing team should identify all variables in the material of choice. Work closely with Thermal Process Holdings to share your journey to making a high end quality product. The material should be normalized processed at the appropriate temperature and time to meet the application demands.

A review of the manufacturing process will inform the supplier what the highest manufacturing temperature the component will be exposed to. The material will ultimately respond according to the highest manufacturing process temperature. A good manufacturing practice is to perform a normalize process 50˚F above the highest manufacturing process temperature.

What is Normalizing?

Heating your material to a predetermined, elevated, temperature and then allowing it to slowly, air cool to room temperature. The material will develop a uniform fine grain structure. Pearlite (Fe3C) and cementite is the make-up of this normalized homogeneous structure. As a result of proper normalizing, machining should become optimal.

For most materials, normalizing will reduce the material hardness and increase the ductility. However, this is not true for all ferrous materials so it is vital to check and understand before manufacturing begins.
