GEN 308L is ideal for welding Types 304L, 321, and 347 stainless steels. This is a suitable wire for applications at cryogenic temperatures.
GEN 308L Overview
GEN 308L has the same chemical composition as GEN 308, except the carbon content has been held to 0.03%
maximum to reduce the possibility of intergranular chromium carbide precipitation. It is commonly used to
weld stainless steel type 304L, 321 and 347. Depending on temperature range and flux selection, GEN 308L is
a suitable filler metal for applications at cryogenic temperature.
