We supply hobart aws DESCRIPTION: HOBALLOY 10018D2 is an high quality electrode for high tensile steels and manganese molybdenum steels. The coating is specially formulated to resist moisture pick-up under conditions of high heat and humidity. The electrode offers resistance to moisture reabsorption which helps prevent hydrogen cracking and aids in elimination of starting porosity. Definitely a preferred electrode with high operator appeal. APPLICATIONS: HOBALLOY 10018D2 is designed for applications requiring at least 100, 000 psi tensile strength, good ductility and crack resistance. Typical applications include manganese-moly castings, alloy forgings, structures and pressure vessel applications in either the as welded or stress relieved conditions. FEATURES: BENEFITS: • Good arc characteristics • Stable, easy to control arc • Good ductility • High impact resistance • Low spatter level • Improves weld bead appearance, higher deposition • Quick and easy slag removal • Reduces clean-up time • Low moisture reabsorption • Prevents starting porosity • Low smoke level • Welder safety and comfort • Low hydrogen, less than 4 ml/ 100 g • Resistant to hydrogen-induced cracking TYPICAL WELD METAL PROPERTIES* ( Chem Pad) : TYPICAL MECHANICAL PROPERTIES* ( SR) : TYPICAL CHARPY V-NOTCH IMPACT VALUES* ( SR) : DIFFUSIBLE HYDROGEN: 2.2 ml/ 100 gr CONFORMANCES AND APPROVALS: • AWS A5.5, E10018-D2 H4R, ASME SFA 5.5, E10018-D2 H4R * The information contained or otherwise referenced herein is presented only as “ typical� without guarantee or warranty, and Hobart Brothers Company expressly disclaims any liability incurred from any reliance thereon.
