I am busy developing a High pressure Steam Spec
Using ASTM A335 P11 Pipe material I am not sure what material to use for fittings
In B31.3 I only find A182 F11 CL 2 but the Tensile and yield are different from my pipe.
And in the material spec ASTM A182 I find a A182 CL 1 with the same yield and tensile limits as my pipe but this grade cannot be found in B31.3

Please advise?
