Nihonweld NSS-309MoL description: NSS-309MoL is a lime-titania type electrode for all-position welding, which have good usability and good weldability. Good resistance against dilute sulfuric acid compared with that of NSS-309MoL. Weld metals provide excellent corrosion resistibility and heat resistibility in the as-welded condition. As NSS-309MoL is of low carbon content, it can be used for welding of extra-low carbon stainless steel which contains Mo and for under laying of mother plates which contain considerably high carbon content.
