Stainless Steel 316 Welded ERW Micro Tubes are precision manufactured small diameter tubes that are used for applications that demand dimensional accuracy, consistent weld quality and excellent corrosion resistance. Made from SS 316 strip by Electric Resistance Welding (ERW), these Micro Tubes can be cold drawn to produce precise dimensions and smooth surfaces. The common chemical composition of the material is 16.0-18.0% Chromium, 10.0-14.0% Nickel and 2.0-3.0% Molybdenum; this makes the material highly resistant to environments that contain chlorides. Additionally, the minimum tensile strength of SS 316 is 515MPa while the yield. These tubes can be used in medical instruments for instrumentation, analytical equipment, aerospace systems and precision fluid handling. USA Pipings Solution is a supplier of Stainless Steel 316 Welded ERW Micro Tubes in custom dimensions and specifications.

Frequently Asked Questions
What are Stainless Steel 316 Welded ERW Micro Tubes?
Stainless Steel 316 Welded ERW Micro Tubes are small-diameter tubes made from SS 316 strip using electric resistance welding, offering precision, strength, and corrosion resistance.
What is ERW tubing and how is it manufactured?
ERW tubing is manufactured by forming a stainless steel strip into a tubular shape and joining the edges using electric resistance heat and pressure.
Are Stainless Steel 316 ERW Micro Tubes corrosion resistant?
Yes. SS 316 provides excellent corrosion resistance, particularly against chloride-containing and chemical environments, due to its 2–3% molybdenum content.
What sizes are available for SS 316 Welded ERW Micro Tubes?
They are available in various small outer diameters and wall thicknesses, with dimensions customized according to application requirements.
Can SS 316 Welded ERW Micro Tubes be customized?
Yes. They can be customized in outer diameter, wall thickness, length, surface finish, and other specifications.
