TIG-stavar

Copper-coated 0.5Mo-alloyed welding wire for TIG welding of low-alloy creep-resistant steels containing 0.5% Mo such as DIN 15Mo3, 17Mn4 or equivalent according to other standards. OK Tigrod 13.09 is used in constructions such as pressure vessels and boilers with working temperatures up to 500°C. The wire is also suitable for welding high-strength steels such as Weldox 500 and similar qualities.
