201 304 316 Stainless Steel Pipe Price With Best Prices are often corroded and affect its performance in normal use. What are the types of corrosion? Usually pitting corrosion, intergranular corrosion, and stress corrosion and so on. These corrosions will cause more or less damage to the pipe itself.
1. Pitting corrosion
It is the localized corrosion on the pitting surface of 201 304 316 Stainless Steel Pipe Price With Best Prices due to the micro-battery effect caused by surface defects, pores and inclusions. This corrosion can penetrate deep into the thick-walled stainless steel pipe until it penetrates the inside of the pipe. Compared with the uniform corrosion of the pipe surface, pitting corrosion is more harmful.
2. Intergranular corrosion
It is the corrosion along the grain boundary, which is called intergranular corrosion. Intergranular corrosion is a very serious damage to stainless steel pipe because it usually does not change the appearance of the steel pipe, causes damage to the particle odor at the joint, and greatly reduces the mechanical properties of the stainless steel pipe. And this adverse effect is often not easy to detect and can cause sudden damage.
3. Stress corrosion
Stressed stainless steel pipe corrosion refers to the corrosion of 201 304 316 Stainless Steel Pipe Price With Best Prices caused by the combined action of stress including cold working, welding, heat treatment, etc. Its failure characteristics are brittle fractures, mainly along grain boundaries and transgranular fractures.
