We specialize in providing Stainless steel 304 micro tubing engineered with excellent precision and material integrity for a wide array of applications across numerous industries. Our 304 stainless steel micro tubes are a trusted and cost-effective solution for miniature and critical systems requiring good corrosion resistance and formability.
What Are SS 304 and 304L Micro Tubes?
SS 304 micro tube (UNS S30400 Micro Tube) and its low-carbon variant, 304L micro tube (UNS S30403), are the most widely used austenitic stainless steels for micro-applications. Grade 304 is known for its excellent combination of corrosion resistance, formability, strength, and weldability, making 304 SS Micro Tubing and Stainless Steel 304 Micro Tubes a versatile choice.
The "L" designation in 304L micro tube signifies a lower carbon content (typically ≤0.03%). This reduced carbon minimizes chromium carbide precipitation during welding or exposure to elevated temperatures, thereby preserving intergranular corrosion resistance in the heat-affected zone. For this reason, 304L stainless steel micro tubing is often preferred for applications involving welding or those requiring maximum corrosion resistance after thermal processing. Whether it's a Seamless SS 304 micro tube for consistent properties or Precision 304 micro tubing for intricate designs, this grade offers a reliable and economical solution for Micro size SS 304 tubing needs.
Key Properties & Advantages of Our SS 304 Micro Tubes
Choosing Amardeep Steel's SS 304 micro tube, 304L micro tube, and broader range of Stainless Steel 304 Micro Tubes provides significant benefits:
