YAWATA BLACK-71 (For 490N/mm2 High Tensile Strength Steel)
Classification : AWS A 5.20 : E71T-1-C1[M21]A0-CS1-H8, JIS Z3313 : T49J0T1-1CA-U H10
Approvals : ABS
Applications : All position welding of mild and medium strength steel for building, shipbuilding, bridges, machineries, vehicles, offshore structures and general fabrications.
YAWATA BLACK-71 is a titania type flux cored arc welding wire for all position welding with CO2 shield gas. The wire is baked giving it the distinct black colour appearance. The baked wire has very good feedability, excellent anti-rust property and low fume generated. Suitable for welding of building, shipbuilding, bridges, machineries, vehicles, offshore structures and general fabrications.
