Hot bluing is a process of anti-corrosion mechanical protection of metals, and it is also used for decorative purposes. It enables the blackening of pieces. The workpiece becomes a characteristic black color that does not reflect light.
Bluing does not change the properties of the workpieces, and it can also be used for more demanding shapes.
During bluing, no additional layers of metal are applied (as, for example, with gavanization), so the dimensions remain the same. Cleaned metal objects are heated to a temperature of 400 to 600 degrees Celsius.
For an optimal result of hot bluing, the products must then be coated with a special emulsion, wax or oil, and metals treated in this way are suitable for indoor use.
Advantages of hot bluing over electroplating:
In addition to the fact that hot bluing does not change the dimensions of the workpiece and its properties, an important advantage is that blued parts can be welded without prior preparation, and no toxic gases are produced.
Only steel, cast iron or stainless steel can be blued. Parts made of aluminum or polymer are not treated with the hot bluing process, as the chemicals used in the process unevenly color such workpieces and react strongly, which can also cause chemical burns.
When is the bluing process used?
The activity that perhaps makes the most use of hot bluing is the gun industry. Adequate protection of weapons is important in gunsmithing, and at the same time bluing prevents light reflection.
In addition to use in weaponry, our company is also trusted with hot bluing by customers from the tool, furniture, and automotive industries. We deal with:
If you are not interested in hot bluing, we can also offer quality induction tempering. For this process, too, we have the most modern technology available, all the necessary knowledge and experience, and we guarantee the shortest possible time for implementation.
