Thermal conductivity of stainless steel is worse than that of ordinary steel, much worse than that of copper. In the process of compressing Oxygen, the heat transfer is about 5 times bigger than with air. These heat waves may propagate through the piping to where they could do damage. Our fire squad had pretty burnt angles in their stainless steel ping system, but that was with aair, and a high power compressor. I would continue to use stainless steel, but only equippped with inline needle valves to throttle the flow down. Just my 2pence.
