FITOK 2.6% Mo Seamless Stainless Steel Tubing


Steel Tubing


What are the advantages of enhanced-316/316L tubing



Except for ordinary type 316/316L steel, FITOK tubing can also be supplied in enhanced-316/316L. Ni, Cr, and Mo contents of the material are in close approximation to upper values defined in ASTM requirements, among which, molybdenum content exceeds 2.6%. With increased molybdenum content, enhanced-316/316L tubing shows improved pitting corrosion resistance and performs better in the corrosive marine environment containing chlorides.

Meanwhile, as the material maintains a stable organizational structure, enhanced-316/316L tubing is ideally used in high-pressure hydrogen applications where hydrogen embrittlement exists.

Chemical compositions and mechanical properties of the tubing are detailed as below:
