Looking for an Electrode selection to repair a kiln tyre made from A 551 class c Have contacted Eutectic as they may be able to match up the chemical composition . But any suggestions would be helpfull ..

RE: A-551 class c
For weld build-up (worn) or groove weld repairs (cracks), you have several possible filler metal options for either repair approach that do not require a match to the base material. Lower strength filler metals may well be the approach. Either way your main hurdle will be making sure you have enough preheat applied (500 deg F) to the existing ring with low hydrogen consumables to avoid delayed cracking.

If you are performing a weld build-up of the worn (spalled) surface I would use AWS 5.11 ENiCrFe-3 (Inconel 182), which is a Nickel-base filler metal. Despite the lower strength, this filler metal is very ductile and will work harden in service.
