Supply & Demand

Bright Annealed Stainless Steel Seamless Tubes(BA Tubes) are primarily used in precision instruments,medical equipment,automotive piping,high-purity gas or liquid transportation,and the semiconductor industry. The surface of BA tube is smooth,with low internal surface roughness and high precision tolerances.

Electropolished（EP）Stainless Steel tubes are mainly used in instruments,high purity gas or liquid transportation,semiconductor and other industries with high cleanless requirements.

Production procedure: Raw elements (C, Fe, Ni, Mn, Cr and Cu), smelted into ingots by AOD finery, hot rolled into black surface, pickling into acid liquid, polished by automatically machine and cutting into pieces.
