Corresponding Standard	DIN EN 10305-1-2003 Steel Tubes for Precision Applications – Technical Delivery Conditions – Part 1: Seamless Cold Drawn Tubes
Classification	Carbon Steel

E355 Chemical Element Composition Content (%)

Component	C	Si	Mn	P	S
Minimum Value	-	-	-	-	-
Maximum Value	0.22	0.55	1.6	0.025	0.025

① Additions of Nb, Ti and V are permitted at the choice of the manufacturer. Indicate the proportion of these elements.
② For the steel grades E235, a controlled sulfur content ranging from 0.015% to 0.040% is specified to improve the machinability. It is to be adjusted by resulfurization of the steel after maximum desulfurization or alternatively by secondary metallurgical processes with a reduction of the oxygen content.
