Stainless steel fabrication for high temperature steam application

[tamal1475]

Usually for corrosion applications we mandate precautions to be taken against iron contamination during austenitic stainless steel fabrication. Should it apply for high-temperature applications also, as for steam boilers? Normally local iron contamination on an austenitic stainless steel component, in an aqueous corrosive atmosphere, will result in local corrosion leading to failure. Such risks do not exist in high-temperature application where heat-resistant stainless steels are used for their high-temperature properties. I seek comments from learned members and request them to share their experience.
