Note E: Grades TP 347 shall have a columbium plus tantalum content of not
less than ten times the carbon content and not more than 1.0
%.

Note A:Grades TP 304L and TP 316L shall have a minimum tensile strength of
70 ksi (485 MPa) and a minimum yield strength of 25 ksi (170
MPa).Note B: Yield strength is not generally determined on tubing sizes smaller
than 1/8 in. (3.2 mm) in outside diameter or thinner than
0.015 in. (0.38 mm) wall, so yield strength is not required on such
sizes. Also, the minimum elongation required on these smaller or
thinner sizes is 25 %.
