What is the corrosion resistance of china Stainless steel profile
China Stainless steel profile is a common stainless steel profile. So, is it as corrosion-resistant as other stainless steel profiles? The corrosion resistance of china Stainless steel profile depends on chromium. The fundamental reason is that the addition of chromium as an alloying element in steel can promote the development of internal contradictory movements and is beneficial to corrosion damage. So how does chromium make china Stainless steel profile corrosion resistant? Reflected in the following two aspects:
1. Chromium increases the electrode potential of iron-based solid solution
When chromium is added to the iron-based solid solution, the electrode potential will rise, and when the chromium reaches a certain concentration, the electrode potential will change suddenly. When the chromium content reaches a certain proportion, the electrode potential of the iron-based solid solution rises sharply, and the corrosiveness is greatly reduced. At this time, the china Stainless steel profile can resist the corrosion of the atmosphere, water vapor and dilute nitric acid.
Chromium can be said to be an element that determines the corrosion resistance of china Stainless steel profile. It has a great influence on the performance of stainless steel profiles. Perhaps in the past, the understanding of the corrosion resistance of stainless steel profiles is that it is a kind of stainless steel, so it will not rust.
2. Chromium absorbs electrons from iron and passivates it
When steel is alloyed with chromium, the type of surface oxide changes to be similar to that formed on pure chromium metal. This tightly adhered chromium-rich oxide can protect the surface from corrosion and prevent further oxidation. In addition, the oxide layer is very thin. Through it, you can see the natural luster of the steel surface, giving the china Stainless steel profile a unique surface. In addition, if the surface layer is damaged, the exposed steel surface will react with the atmosphere, repair itself, re-form an oxide "passivation film", and continue to protect the stainless steel profile from corrosion.

What is the difference between carbon steel pipe and carbon steel coil pipe
Carbon steel pipe made of carbon steel coil pipe is a seam pipe. Compared with seamless steel pipe, the quality of seamless steel pipe is better than that of seam pipe due to the quality assurance of material and weld. The pressure components of pressure equipment must use seamless steel pipes. Generally, non-pressure-bearing structures or structural parts can use carbon steel coil pipes with slits.
