What Makes Grade 316 Stainless Steel Ideal for Small Diameter Tubes?


Molybdenum added to Grade 316 stainless steel makes it far more resilient to corrosion and chemical attack than common stainless steel grades. For this reason, this particular grade of stainless steel finds much of its use in environments exposed to chemicals, chloride, seawater, and moist surroundings.

Key Advantages:

  •   Excellent resistance to pitting and crevice corrosion
  •   Superior performance in chemical processing applications
  •   High temperature resistance
  •   Good weldability and fabrication properties
  •   Excellent strength-to-weight ratio
  •   Hygienic surface suitable for pharmaceutical and food industries
  •   Long service life with minimal maintenance

Because of these benefits, Grade 316 micro tubing is preferred for critical applications where reliability and precision are essential.

Frequently Asked Questions


What is the difference between 316 and 316L small diameter tubes?

316L contains lower carbon content than 316, providing improved weldability and enhanced resistance to intergranular corrosion after welding.

Where are SS 316 capillary tubes commonly used?

SS 316 capillary tubes are widely used in medical devices, analytical instruments, chromatography systems, instrumentation equipment, and fluid control applications.

Why is Grade 316 preferred over Grade 304?

Grade 316 contains molybdenum, which significantly improves corrosion resistance, especially in chloride-containing environments.

What sizes are available for stainless steel miniature tubing?

Miniature tubing is available in outer diameters ranging from less than 1 mm up to approximately 25 mm, depending on application requirements.

Is seamless tubing better than welded tubing?

For high-pressure and critical applications, seamless tubing generally offers superior strength and reliability because it does not contain a weld seam.
