Note:

Where a ellipsis(﹍)appears in the table, there is no requirement and the element need to be analyzed for or reported

The method of analysis for nitrogen shall be a matter of agreement between the purchaser and manufacturer

Columbium 0.10-0.30%; Vanadium 0.10-0.30%.

For small diameter or thin walls, or both, where many drawing passes are required, a carbon maximum of 0.04% is necessary in grades TP304L and TP316L. Small outside diameter tubes are defined as those less than 0.500in.(23.7mm) in outside diameter and light wall tubes as those less than 0.049in.(1.24mm) in average wall thickness
