\u25b6\ufe0e Characteristics: stainless steel TIG rod<\/strong><\/h5>\n

LKT\/LKM-409Nb is a ferritic stainless steel filler wire suitable to weld 409 or 409Ti base stainless steels. The addition of niobium results in a preferential reaction with carbon, which prevent the chromium from forming carbides. This improves corrosion resistance, increases strength at elevated temperatures and promotes a ferritic microstructure. It is used primarily in the automotive industry for welding catalytic converters and other parts of the exhaust system. For best results, welding must be done in a low heat input procedure and is not recommended for multi-pass applications.<\/p>\n

\u25b6\ufe0e Notes on Usage:<\/strong><\/h5>\n

1. For TIG process, use DC(-) current , Argon Shield and Tungsten Electrode.<\/p>\n

2. For MIG process, use Spray Transfer or Short Circuit Transfer mode.<\/p>\n

3. 98%Argon \u2013 2%O\u2082\u00a0<\/span>shielding gas is recommended in MIG process.<\/p>\n
