What Are Stainless Steel Micro Tubes?
Stainless Steel Micro Tubes, also known as Micro Stainless Steel Tubing, Small diameter stainless steel tubing, or even Micro-sized stainless steel pipes in some contexts, are characterized by their exceptionally small outer diameters (OD), often featuring Thin wall stainless steel micro tubing designs, and are manufactured with high-precision. These Precision stainless steel tubes are specifically designed for applications where space is critically limited, fluid or gas volumes are minute, and extreme accuracy is paramount. This category often includes Capillary stainless steel tubes, known for their very fine bores.
Unlike standard tubing, SS micro tubes undergo specialized manufacturing processes, frequently involving precision cold drawing and meticulous quality control, to achieve their minute dimensions and critical tolerances. They are essential components in advanced instrumentation, medical devices, electronics, analytical equipment, and other fields requiring miniature fluidic or structural elements. The inherent properties of stainless steel, such as exceptional corrosion resistance and robust strength, are retained even at these micro scales, making Stainless Steel Micro Tubing the material of choice for these exacting uses.

Common Grades for Stainless Steel Micro Tubes
We offer Stainless Steel Micro Tubes, including Capillary stainless steel tubes, in a variety of grades to suit specific environmental and performance requirements. The most commonly requested include:
Stainless Steel 304 Micro Tubing / 304L Micro Tubing
SS 304 Micro Tube / 304L Micro Tube is the most widely used austenitic stainless steel, valued for its good general corrosion resistance, excellent formability, and reliable strength. The lower carbon content in the "L" grade enhances weldability, making it a versatile choice for general instrumentation, food and beverage components, automotive parts, and consumer electronics where moderate corrosion resistance is sufficient for SS micro tubes.
Small Diameter Stainless Steel 316 Tubing / 316L Micro Tubing
SS 316 Micro Tube / 316L Micro Tube is an austenitic stainless steel alloyed with molybdenum, delivering excellent corrosion resistance, especially against chlorides and acidic environments. The low carbon "L" grade (316L micro tube) offers improved weldability, making Stainless steel 316 micro tubing ideal for demanding applications such as medical devices, pharmaceutical processing, marine components, chemical lines, and analytical instrumentation requiring superior corrosion resistance in Small diameter stainless steel tubing.

Frequently Asked Questions about Stainless Steel Micro Tubes
How do stainless steel micro tubes differ from standard tubing?
Stainless steel micro tubes are ultra-small, precision-engineered tubes with outer diameters often less than 1 mm and very thin wall thicknesses. Unlike standard tubing, they are manufactured using high-precision processes like cold drawing to achieve extremely tight tolerances. This makes them ideal for miniature applications such as fluid delivery in medical devices, sensors, and instrumentation systems—especially where space is limited and high accuracy is essential.
What stainless steel grades are commonly used for micro tubes, like SS 304 and SS 316?
The most common grades are austenitic stainless steels:
- SS 304 micro tube / 304L micro tube: Offers good general corrosion resistance and formability at a relatively lower cost.
- SS 316 micro tube / 316L micro tube: Contains molybdenum, providing superior corrosion resistance, especially against chlorides and acids. Stainless steel 316 micro tubing is often preferred for medical, marine, and more aggressive chemical environments.
What is the typical size range (OD and wall thickness) for your Stainless Steel Micro Tubes?
We offer a wide range of Small diameter stainless steel tubing. Typically, ODs can range from as small as 0.2mm (0.008") up to around 6.35mm (0.250"). Wall thicknesses can be very fine, often starting from 0.05mm (0.002") for Thin wall stainless steel micro tubing. We also provide Precision stainless steel micro tubes to custom dimensions.
Are your Stainless Steel Micro Tubes seamless or welded?
The majority of true Stainless Steel Micro Tubes, especially those for high-pressure or critical medical/analytical applications, are Seamless stainless steel micro tubes. This ensures maximum integrity and uniformity. However, very fine welded and redrawn options might be available for specific applications or larger "micro" sizes. Please specify your requirements.
What kind of dimensional tolerances can be expected for Precision stainless steel tubes?
Due to their precision manufacturing, SS micro tubes can be produced with very tight dimensional tolerances for OD, ID, and wall thickness, often much tighter than standard tubing. Typical OD tolerances might be around +/-0.005” (+/-0.13mm) or better, with wall tolerances around +/-10% or tighter, depending on the size and manufacturing process. We can discuss specific tolerance requirements for your project.
Can Amardeep Steel provide custom-sized or custom-length micro tubes?
Yes, as a leading Manufacturer and Supplier in India, Amardeep Steel specializes in providing custom solutions. We can manufacture Stainless Steel Micro Tubing to specific OD, wall thickness, length (straight or coiled for Capillary stainless steel tubes), temper, and surface finish requirements.
What surface finishes are available for SS miniature tubing?
We offer various surface finishes, including Bright Annealed (BA) for a smooth and clean surface, mechanically polished finishes to specific Ra values (e.g., for medical applications), and passivation to enhance corrosion resistance.
