Hot-finished tubes need not be heat treated. Cold-finished tubes shall be given a subcritical anneal, a full anneal, or a normalizing heat treatment after the final cold-finishing process.
The tubes shall have a hardness not exceeding the following: 79 HRB or 143 HRB for Grade A-1,89 HRB or 179 HRB for Grade C.
Hydrostatic or Nondestructive Electric Test —Each tube shall be subjected to the hydrostatic, or,
instead of this test, a nondestructive electric test may be used when specified by the purchaser
In addition to the marking prescribed in Specifi-cation A 450/A 450M, the marking shall indicate
whether the tube is hot-finished or cold-finished.
