S275JR Chemical Element Composition Content (%)

Component	C	Si	Mn	P	S	N	More
Minimum Value	-	-	-	-	-	-	Ceq≤0.4
Maximum Value	0.21	0.35	1.5	0.025	0.02	0.012	Ceq≤0.4

① Other alloying elements can be added as required
② The max. value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % or alternatively min. 0,015 % acid soluble Al or if sufficient other N binding elements are present. In this case the N binding elements shall be mentioned in the inspection document.
