Description
Stainless steel tubing is made from cold rolled stainless steel strip (chemical elements are specially controlled to enhance weldability). Weld bead is cold-worked to a full finished condition for a virtually undetectable longitudinal weld. This is followed by bright annealing to a minimum temperature of 1,900°F in a controlled atmosphere to preserve maximum structural integrity. Tubes are mechanically polished to a 180 grit (20 μ-in. Ra maximum) interior and 150 grit (32 μ-in. Ra maximum) exterior surface finish.

Mechanical Tests: In addition to the standards above, the following tests are also performed: flare, flatten, flange, reverse bend, and eddy current. Surface roughness is measured per ASME/ANSI B46.1 requirements. These measurements are derived from four readings taken at cross sections approximately 90 degrees apart.
