My AI is busting my B@!!s for weld ability on spacer clips made for B&W part number 6660452 and 6660453. On the MTR it only list A297HF , its not listed in Section 9. I need to find the appropriate P number or SA number. The chemical analysis is as follows
C .26 Si .40 Mn .53 P.036 S .013 Cr 18.38 Mo .11 Ni 9.21. im sure someone has run across this problem before. These are stander clips used on spacer tubes on super heat tubes and else where in side the boiler.
