Metinox Overseas is a renowned manufacturer, supplier, and stockist of SS 317L Seamless Tubes. The SS 317L alloy is distinguished by its molybdenum-bearing austenitic stainless steel composition, featuring lower carbon content compared to alloy 317. These Stainless Steel ASTM A213 TP 317L Seamless Tubes not only offer impressive tensile and stress-to-rupture strength but also exhibit enhanced creep resistance at elevated temperatures.

With high chromium content, Stainless Steel 317L Seamless Square Tubes demonstrate excellent oxidation resistance; however, they are susceptible to embrittlement beyond temperatures of approximately 350 degrees Celsius, thus their application is limited to lower temperature environments. Both martensitic and precipitation hardening families of Stainless Steel 317L Rectangular Tubes boast high strengths achievable through thermal treatments.
