Although this process is not limited to stainless steel and can be used with any type of steel, stainless steel retains these colors much better. The principle is very simple: if steel is heated to a certain temperature, it changes color, and this color appears due to the reaction of the top layer with oxygen. These colors are definitely not as persistent as painted surfaces or anodizing, but if you use the part where there is no constant friction, the “paint” lasts a long time.
Craftsman uses this technique in many stainless steel projects. There are several things to consider when performing this technique. If you look at the diagram of the heating of steel, before it reaches red heat, it goes through many stages of different colors. Some of them “fix”, while most of them acquire color temporarily, and when the metal cools, it turns black.
He uses 304 stainless steel for his projects. AISI 304 is a low carbon austenitic steel. In Russia, according to GOST, its analogue is steel grade 08X18H10. AISI 304 stainless steel is acid resistant and can withstand short-term temperature rises up to 900 degrees Celsius.
Tools and materials:
– Parts from stainless steel grade 304
– Waste engine oil;
– Brush made of brass wire;
– Acetone or mineral alcohol;
– Refractory brick;
– Burner;
– Pliers;
The metal workpiece must have a smooth surface. Firstly, it looks beautiful, and secondly, on a flat, smooth surface, the heat distribution is much better.
The important thing to do is clean the surface. Make sure there is no dirt left on the surface, and once the metal is completely cleaned, do not touch it, because there is always a little grease on your hands. Gloves are best used.
Technique of 'painting' stainless steel As soon as cleaning is finished, you can start the heating process. If you look at the diagram, you can see how the color changes depending on the temperature.
An important point to consider here is the property of steel. Steel has a very low thermal conductivity, which means that if a certain area is heated, it will not be able to distribute the heat evenly over the entire surface, resulting in an uneven color spectrum. Those. it is necessary to constantly move the burner throughout the entire process so that the heat does not concentrate on a specific area.
In this article, the wizard only demonstrates two colors. The reason for choosing them is that they are quite easy to obtain and very easy to control during heating. The key to success here is to act slowly and distribute heat evenly.

The oil needs used up, which has become completely black. The darker the oil, the better the result will be. For this particular color, you need to heat the steel to blue, or about 300 ° C, and then immediately dip it in oil. At the same time, make sure that until the material has completely cooled down, do not wipe off the oil from the surface of the part. As soon as it cools down, wipe off the oil with acetone.

In this case, the part takes on a matt brass color. The essence of the process is as follows. Install the disc with brass wire into the screwdriver. Heat the part to 230 degrees and then grind the part until the brass covers the entire surface. At the same time, unlike simple heating, where the surface will be glossy, in this case the surface will be matte.
