Stainless Steel ER 308 / ER 308L

Technical Data Sheet

Chemical Composition Limits
Weight%	C	Mn	Si	Cr	Ni	S	P	Mo	Cu
ER 308 ER 308 L	0.03	1-2.5	0.30-0.65	19.5-22	9-11	0.03 max	0.03 max	0.75 max	0.75 max

Alloy ER 308L is ideal for welding Types 304L, 321 and 347. This classification is the same as alloy ER 308, except for the carbon content. The carbon content is held to a maximum of 0.03% to reduce the possibility of intergranular carbide precipitation. This increases the resistance to intergranular corrosion without the use of stabilizers such as columbium (niobium) or titanium. Strength of this low-carbon alloy, however, is less than that of the columbium (niobium) - stabilized alloys or Type 308H at elevated temperatures.
