Stainless Steel 317/317L Seamless Tubes: Your Ultimate Guide
Introduction to Stainless Steel 317/317L Seamless Tubes
Metinox Overseas is a renowned manufacturer, supplier, and stockist of Stainless Steel 317/317L Seamless Tubes. Distinguished by its molybdenum-bearing austenitic stainless steel composition, the SS 317L alloy features lower carbon content compared to alloy 317. These stainless steel tubes offer impressive tensile and stress-to-rupture strength along with enhanced creep resistance at elevated temperatures.
Key Features and Advantages
• Oxidation Resistance: The high chromium content in Stainless Steel 317L Seamless Square Tubes ensures excellent resistance to oxidation. However, they are susceptible to embrittlement beyond temperatures of approximately 350 degrees Celsius, limiting their application to lower temperature environments.
• Thermal Treatment Strengths: Both martensitic and precipitation hardening families of Stainless Steel 317L Rectangular Tubes boast high strengths achievable through thermal treatments.
• Corrosion Resistance: SS 317L tubes demonstrate exceptional ...
... resistance against harsh acids, making them ideal for high acid chloride environments.
