Rolled bar for Flange A350 LF2
Rolled bar for Flange A350 LF2
(OP)
Hi,
May I use a rolled bar (which is acc. to 350 LF2) to make a standard flange (e.g. B16.5) and declare it as 350 LF2? The raw material is not a "real" forging...thanks

shaped parts may be machined from rolled bar or
seamless tubular materials provided that the axial length
of the part is approximately parallel to the metal flow lines
of the stock. Other parts, excluding flanges of all types,
may be machined from hot-rolled or forged bar up through
and including NPS 4. Elbows, return bends, tees, and
header tees shall not be machined directly from bar stock.
... means that for hollow cylindrical shapes other than flanges of all types, you could use bar or tubular product forms, etc.
