multiple allowable stress values for N08020 same product
multiple allowable stress values for N08020 same product
(OP)
Why are there multiple stress allowable values for the same product form (seamless tube or welded tube) of alloy 20Cb3 (N08020) in the 2007 edition of ASME BPV code?

Don't forget to look at the other notes. Some specs list both seamless or welded tube and provide the allowable stress for seamless in the table and note derating factors to be applied depending on the type of welding used during manufacture (e.g., single weld 0.85, double weld 0.8, etc. Same for pipe.
