Outershield® 91K2-HSR

Outershield® 91K2-HSR is an all position gas shielded 1.5% Ni and 0.4% Mo, alloyed flux cored wire for pipeline, offshore and structural applications. Specifically designed for stress relieved applications, guaranteed impact properties after PWHT. The wire withstands higher heat input procedures that are typical for mechanised welding of cross country pipelines. Superior weldability, low spatter, good bead appearance and outstanding operator appeal. Exceptional mechanical properties are combined with arc characteristics to produce sound and regular welds. Self releasing slag and regular bead profile after welding in 3Gup position reduce cleaning time and increase productivity.
