Stainless steel pipe fittings do not rust the principle

Date:2017-10-26 Author: Click:

Stainless steel elbow inventory of raw materials, including steel ingot, billet, steel and other raw materials, different raw materials is in use occupies an important position. Steel is the material of various shapes, sizes and properties required for ingot, billet or steel to be formed by press working. Due to the high viscosity of the stainless steel elbow material and poor chip breaking performance, it is easy to occur when the tap of the stainless steel elbow is tapped, so as to affect the processing efficiency and the thread quality. All metals react with atmospheric oxygen to form an oxide film on the surface. Unfortunately, the formation of iron oxide on common carbon steel continues to oxidize, increasing the corrosion and eventually forming voids. Stainless steel elbow surfaces can be secured with paint or oxidation-resistant metal such as zinc, nickel and chrome, however, as is known, this protection is only a thin film. If the protective layer is damaged, the steel below begins to rust.

If it is processed stainless steel pipe then it is not the same, because this is a metallurgical process, from the inside out. Stainless steel pipe stainless steel secret lies in the carbon steel added chromium metal, and the content is not low, at about 12%, he contacted with air after the reaction of chromium with oxygen in the carbon steel surface to form a dense layer of blunt Film, can effectively continue the protection of stainless steel pipe. And this layer of passive film super-thin, can see the natural surface of steel, stainless steel pipe fittings have a very unique surface characteristics. However, there is no guarantee that this protective film will not be damaged. Once the exposed steel is damaged, it will react with oxygen and a new passivation film will be formed to continue its work. Stainless steel pipe above the theory is not rusty, but in fact a lot of environmental humidity levels produced by different levels of corrosion is also normal.
