Alloy Designation Needed
Alloy Designation Needed
(OP)
Ferrous alloy, 0.23Carbon, 1.35 Cr, 0.49 Mo, 0.2 V, 0.66 Si, 0.56 Mn.
It essentially looks like 1¼Cr-½Mo-¼V, but I cannot find a US alloy that fits that designation. Is there a european alloy? The material is a pipe used for a long-retract lance/sootblower and used to be made by Copes-Vulcan, but I am told it is no longer.

Our sootblowers use either air or steam and we have had no serious maintenance or operational problems with the T22 material -as long as the lance does not get stuck in the boiler.

The stainless steel heads should be attached to the lance with Inconel versus 309 filler metal. I do remember that we had requested the Inconel filler metal because we were concerned about thermal stresses from differential expansion and carbon migration.
