Used to weld 18/8 stainless steels including 301, 302, 303, nitrogen bearing 304LN and titanium stabilised 321. Service temperatures are typically –100°C to about 400°C. Applications include food, brewery, pharmaceutical equipment, architectural and general fabrication, and nuclear engineering. The 308L consumables covered here are not suitable for 304/304H in elevated temperature structural applications, see data sheets C-10 and C-12. For cryogenic applications (–196°C) see data sheet B-37
MMA electrode – rutile aluminosilicate flux on high purity 304L core wire giving very low typical carbon level. ‘Low hydrogen’ manufacturing technology ensures high resistance to weld metal porosity. ‘Supermet Technology’ gives acid rutile operability combined with controlled silicon content for maximum cracking/corrosion resistance. Designed for ease of use, exceptional weld bead appearance and high weld metal integrity, primarily in the down hand and HV positions; smaller sizes offer all-positional operability. Recovery is about 115% with respect to core wire, 65% with respect to whole electrode
