D
For small diameter or thin walls or both, where many drawing passes are required, a carbon maximum of 0.040 % is necessary in grades TP304L and TP316L. Small
outside diameter tubes are defined as those less than 0.500 in. [12.7 mm] in outside diameter and light wall tubes as those less than 0.049 in. [1.2 mm] in average wall
thickness (0.044 in. [1 mm] in minimum wall thickness).

The titanium content shall be not less than five times the carbon content and not more than 0.70 %.
F
The titanium content shall be not less than four times the carbon content and not more than 0.70 %.
G
The columbium plus tantalum content shall be not less than ten times the carbon content and not more than 1.10 %.
H
The columbium plus tantalum content shall be not less than eight times the carbon content and not more than 1.10 %.
