DESCRIPTION OK 76.18 is a basic coated, hydrogen-controlled electrode; iron powder type used for welding creep resistant steels of 1.25%, Chromium 0.5% and Molybdenum type. The slag system design is such that the electrode welds with a quite stable arc and gives a minimum amount of spatter and a weld bead that is smooth and even. OK 76.18 welds without short-circuiting and deposits a weldmetal resistant to both cracking and porosity. Root runs can be made easily with the electrode. The weldmetal is resistant to scaling upto 775°C. The weld deposit is of radiographic quality. APPROVALS : PDIL, IBR WELDING CURRENT: DC +, AC 70V TYPICAL APPLICATIONS OK 76.18 is specially used to the welding of 1.25 Cr 0.5 Mo and similar creep resistant steels which find extensive use in high temperature components of power plants, boilers, oil-refineries, petrochemical plants etc. Use for steels of the type ASTM A 182- F2, F11, F12; A387-2, 12; A213-T2, T11, T12; A335-P2, P11, P12 and German steels 13 Cr Mo 44, 15 Cr Mo 5 etc.
