Stainless Steel 316 Micro Tubes Manufacturer & Supplier
Amardeep Steel is a premier Manufacturer, Supplier, and Exporter of high-performance SS 316 micro tube and 316L micro tube products in India. We specialize in providing Stainless steel 316 micro tubing engineered with exceptional precision and superior material integrity for the most demanding applications where corrosion resistance and purity are paramount. Our 316 stainless steel micro tubes are trusted by industries requiring reliable performance in miniature and critical systems.
What Are SS 316 and 316L Micro Tubes?
SS 316 micro tube and its low-carbon variant, 316L micro tube, are austenitic stainless steels renowned for their excellent corrosion resistance, particularly in aggressive environments. The key distinguishing feature of Grade 316/316L over Grade 304/304L is the addition of molybdenum (typically 2-3%). This molybdenum content significantly enhances its resistance to pitting and crevice corrosion, especially in chloride-containing media (like seawater or de-icing salts) and against a broader range of acids and industrial chemicals.
Our Stainless steel 316 micro tubing is manufactured to extremely tight tolerances, making it ideal for applications involving Micro size SS 316 tubing requirements. The "L" designation in 316L micro tube signifies a lower carbon content (typically ≤0.03%), which minimizes carbide precipitation during welding. This makes 316L the preferred choice for welded micro-assemblies, ensuring that the corrosion resistance of the heat-affected zone is maintained. Whether it's a Seamless SS 316 micro tube for high-pressure integrity or Precision 316 micro tubing for intricate devices, this grade offers a superior combination of properties.
Key Properties & Advantages of Our SS 316 Micro Tubes
