The raw materials we procure from suppliers can have different colors (see left image). After heat treatment, the color of the metal surface can change, resulting in various surface colors (see right image). Due to oxidation at high temperatures, the material surface can range in color from straw to blue, depending on the temperature and duration of the treatment. This color variation is caused by differences in the state of the oil on the material and the atmosphere inside the heat treatment furnace, which result in different colors of the oxide film on the product surface. This color difference does not affect the mechanical properties of the product.
