317L pipe fittings are a kind of stainless steel with high corrosion resistance and high heat resistance. They are suitable for chemical equipment and pipelines in high temperature, strong acid and strong alkali environments.317L stainless steel pipe fittings have good toughness in low temperature environments and are suitable for harsh environments such as polar regions and deep sea. The chemical composition of Stainless Steel 317L Butt weld Fittings is: Cr 18-20%, Ni 11-15%, Mo 3-4%, C ≤0.03%. 317L Forged Fittings have good oxidation resistance at high temperatures and reduce the corrosion rate.
