As the appearance level of the modification circle, the tailpipe has a variety of appearance, shape and even color, among which the stainless steel bake blue liner stands out and becomes the most popular modification style at present. If you think stainless steel bluestone is just beautiful, you're wrong. The bluestone process is much more complicated and elaborate than your imagine.

Stainless steel baking process, in simple terms , when we heat the stainless steel liner, chemical substances and oxygen on the surface of stainless steel chemical reaction, will produce a layer of dense metal oxide film attached to the surface of stainless steel. The different colors, such as blue and black, appear because the oxide film changes with temperature. At 300℃, the oxide film is blue, and at 330℃, it is blue and purple. These two colors are gorgeous, so they are the most popular.

The essence of blue baking process is actually to generate a certain thickness of oxide layer on the surface of stainless steel, so it will also enhance the corrosion resistance of the liner, which is in addition to its beauty, another important role. Although stainless steel itself has strong corrosion resistance, but for some places with high perennial humidity, such as northern Australia, the Eastern Triangle region, Western Europe, Hawaii, Indonesia and other places, stainless steel bake blue tail pipe will also become the mainstream trend of modification with superior corrosion resistance.

Of course, blue baking process can also be used for different specifications of stainless steel, GRWA blue tail pipe as an example, we have 304 stainless steel blue tail pipe and 201 stainless steel blue tail pipe two, the same place is the use of A level polishing treatment to make the surface look more bright, and the use of 3 times welding way to make the weld more firm.

However, the difference between the two is that 304 stainless steel contains 8% nickel, the liner corrosion resistance is stronger; While 201 stainless steel has a 60% steel density, the tip density is less, and the weight is lighter.
