201 304 304L 316 310s 317L 321 309S 904L stainless steel seamless pipes tubes 6mm

Stainless steel is known as a compound of iron and carbon, with major chromium content ranging from 10.5% to 11.5%. Stainless steel seamless tubes were formed in the 19th century, but it was not until the early 20th century that stainless steel seamless tubes began to be mass-produced and widely used, and the secret of the chromium content of the stain resistance has been discovered. A corrosion barrier is formed when chromium and oxide come into contact with a chromium trioxide steel surrounded by chromium trioxide. Whenever the chromium trioxide layer is destroyed, it "repairs itself" and goes on to produce another piece that interacts with oxygen.
