ASTM A270 / A270M UNS S30403

Chemical Properties

Carbon	Manganese	Phosphorus	Sulfur	Silicon	Nickel	Chromium

Note B: 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 mm] in outside diameter and light wall tubes as those less than 0.049 in. [1.24 mm] in average wall thickness (0.044 in. [1.12 mm] in minimum wall thickness).
