1. Iron Layer
The iron layer is the primary component of a stainless steel pipe, accounting for over 50% of the entire structure. It primarily provides strength and corrosion resistance.
2. Chromium Layer
The chromium layer surrounds the iron layer, primarily enhancing the stainless steel pipe's oxidation and corrosion resistance, preventing surface rust, discoloration, and wear. Stainless steel pipes typically have a chromium content of at least 13% to exhibit good corrosion resistance.
3. Nickel Layer
The nickel layer, located between the iron and chromium layers, enhances the pipe's strength and ductility while protecting the iron layer from oxidation. Stainless steel pipes with a nickel content of at least 8% are typically referred to as "nickel alloys."
4. Carbon Layer
The carbon layer acts as a heat dissipator in the stainless steel pipe. Its function is to reduce the pipe's coefficient of expansion while increasing its hardness and wear resistance, making it more durable.
