Metal for hot service 1200 Degrees Centigrade
(OP)
I am looking for a weldable metal that can provide useful service at about 1200 degree C 253MA (UNS S30815) does not meet the requirements
Thanks
Thanks

Info I have suggests Sandvik's Alloy 601 (UNS No. NO6601) is good to 1200degC. It is welded with filler metal NiCrFe-3 or Sanicro 72. I think it may be worth contacting Sandvik and stating the service parimeters and furnace gas constituents.
Possibly 446 (UNS No. S44600)may work as it has a stated higher temp, rating than 253MA, but again the furnace atmosphere may have a bearing.
Good luck.
