ASTM A632 Grade TP347

Chemical Properties

Carbon	Manganese	Phosphorus	Sulfur, max	Silicon	Nickel	Chromium	Columbium + Tantalum

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 %.

Mechanical Properties

Tensile Strength, min, ksi [MPa]	Yield Strength, min, ksi [MPa]	Elongation in 2 in. min, %

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 %.
