403 stainless steel pipe

Stainless Steel 403 pipes are a type of alloy steel which contain a varied set of chemical elements. These include chromium, nickel, silicon, and various other stop-start elements such as molybdenum, sulfur and phosphorus in varying amounts. The chromium content gives the steel its rust and corrosion resistance while providing hardness, strength and low resistivity to high temperatures. Stainless steel 403 is the optimal choice for many applications where it can be exposed to high temperatures and corrosive environments like those found in food processing factories or pipeline systems delivering acid rainwater runoff.

403 Stainless Steel Pipes offer a reliable and long-lasting solution for many pipe-related needs. One of its most common uses is in cryogenic applications, where its high-temperature resistance makes it an ideal choice. It also offers excellent weldability, corrosion resistance and formability, which make it highly versatile and suitable for multiple applications, including petrochemical, food processing, automotive and medical industries.
