Semiconductor fabrication facilities require ultra-high-purity (UHP) stainless steel tubing to transport process gases with minimal contamination. Key considerations include:
-
Electropolished Surface Finish: Internal surface roughness must be controlled to Ra ≤ 0.25 μm to prevent particle adhesion and maintain gas purity.
-
Low-Sulfur 316L Stainless Steel: Sulfur content below 0.005% is necessary to improve weldability and prevent contamination.
-
Orbital Welding: The semiconductor industry relies on automatic orbital GTAW (gas tungsten arc welding) with 99.999% pure argon shielding to ensure defect-free welds.
