**Stainless Steel 317 and 317L EFW Pipes** contain 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, which offers superior resistance to pitting, crevice corrosion, and a wide range of chemical agents. 317L, the low-carbon variant, contains a maximum carbon content of 0.03%, making it perfectly suited for welded applications through a reduction in the risk of intergranular corrosion. Such pipes generally provide tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of approximately 35%. The EFW process enables large pipes to be produced with high structural integrity and corrosion resistance.

**Stainless Steel 317 and 317L EFW Pipes** are popular for applications with high corrosive and high-temperature conditions. They are usually used for process piping, heat exchangers, condensers, chemical tanks, and flue gas scrubbers. Their high resistance towards acidic chemicals such as sulfuric and phosphoric acids renders them suitable in aggressive chemical and pulp environments. The good weldability of 317L provides for safe and long-lasting construction of joints in large-scale piping systems. These pipes provide extended service life, better performance, and less maintenance in harsh and demanding operating conditions.
