Characteristics:<\/strong><\/span><\/p>\n

LFC-811B2 is a gas-shielded and rutile \ufb02ux cored wire intended for 1-1.25%Cr-0.5%Mo low alloy steel. Use 100% CO2 shield gas.With good weldability ,stable arc, less spatter and good bead appearance in all position welding.<\/p>\n

Applications:<\/strong><\/p>\n

It is suitable for welding Cr-Mo steel pipe and Cr-Mo steel with requiring high creep resistance.<\/p>\n

Notes on Usage:<\/strong><\/p>\n

    \n
  1. Use DC(+) polarity.<\/li>\n
  2. Use 100% CO2 shielding gas.<\/li>\n
  3. Pre-heat at 150-300\u00baC and PWHT at 620-720\u00baC.<\/li>\n<\/ol>\n
