Material AISI316, outer tube diameter 8mm 0.8mm thick. Purge gas Argon 99.995 purity. However found discoloration at internal surface one direction. Strange to know happening only less than 8mm tube. We used same machine for diameter 10mm 0.8 thickness and observed no any discoloration. Kindly suggest any value. Purge injector is made of Mild steel. Is that may be a problem?
