Most austenitic steels, such as Alloy Steel F1 Threaded Flanges, with chromium contents of at least 18 %, can be used at temperatures up to 870 Degree C. Other metals in contact with Alloy Steel F1 Weld Neck Flanges, particularly in a damp or acidic environment, may suffer galvanic corrosion even though the stainless metal may be unaffected.
