Seamless tubular products are made by one of two hot forging process, rotary piercing and rolling, or extruding. seamless tubing is different than steel bar – because of the hole – there are many similarities to the extent that seamless tubing is frequently referred to as “hollow bar”.

 

Pipes according to ASTM A312
Grade	C	Mn	P	S	Si	Cr	Ni	Mo
TP 304	0.08	2.0	0.045	0.030	1.0	18.0-20.0	8.0-11.0
TP 304L	0.035	2.0	0.045	0.030	1.0	18.0-20.0	8.0-13.0

Note:
For small diameter or thin walls or both, where many drawing passes are required, a Carbon maximum of 0.040% is necessary in grades TP 304L and TP 316L. Small outside diameter tubes are defined as those less than 0.50 in. [12.7 mm] in outside diameter and light wall tubes as those less than 0.049 in. [1.20 mm] in average wall thickness (0.044 in. [1.10 mm] in minimum wall thickness).
