Wire Characteristics
●Specially formulated to offer enhanced impact toughness than can be achieved by carbon steel solid wires such as SDX S2, SDX EM13K, SDX S2Si-EM12K or SDX 3Si-EH12K .
●Seamless wire design virtually eliminates risk of moisture absorption and produces low hydrogen weld deposits
●Unique manufacturing process provides unmatched product consistency
●Composite (cored) wire can offer improved deposition rates compared to solid wires at comparable welding parameters
●Composite (cored) wires offer broader penetration profiles compared to solid wire at comparable welding parameters

Approvals
Maintaining a proper welding procedure - including pre-heat and interpass temperatures - may be critical depending on the
type and thickness of steel being welded.
BENEFITS
●Helps to minimize the risk of cracking in demanding service conditions and the risk of cracking caused by improper depth-to-width ratio
●Assists in maintaining a low hydrogen process to minimize the risk of hydrogen-induced cracking
● Provides excellent uniformity of chemical properties, mechanical properties and arc characteristics
●Provides potential to increase travel speed for improved productivity
●Helps to prevent burn-through when welding at high currents on root passes and relatively thin materials
