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.
E308 Electrode Specification Meaning
USA 308 electrodes are used for welding austenitic 18% Cr. – 8% Ni stainless steel types: AISI 301, 302, 304 and steel castings of similar composition such as rust-proof or ferritic steels. USA 308 electrodes. 308L Stainless Electrodes. Description: Stainless Steel Electrodes. Typical Application: Similar usage as 308, but the 0.04% maximum carbon content increases resistance to intergranular corrosion.
