Description
NSS-308L is a premium austenitic stainless steel welding electrode designed for joining and overlaying AISI 301, 302, and 304 stainless steels. Its lime-titania coating offers a soft, stable arc and outstanding weld puddle control, making the electrode suitable for all-position welding, including vertical and overhead.
Engineered for corrosion-resistant applications, NSS-308L provides ductile, crack-resistant weld deposits and maintains strength under elevated temperatures. With excellent slag detachability and spatter-free performance, it enhances productivity and finish quality in both workshop and field environments.
