Frequently Asked Questions
Können ETP copper sein welded?
ETP copper ist nicht recommended für welding because der oxygen content können react mit hydrogen bei elevated temperature, causing steam embrittlement (hydrogen embrittlement). Für welded applications, verwenden oxygen-kostenlos copper (C10200) oder phosphorus-deoxidized copper (C12200).
