K-91T description:
Wire is a titania type of flux cored wire for 630MPa class tensile strength steel welding.
K-91T is recommended for single-and multiple-pass welding in all position with 100% CO2 shielding gas.
It makes good low temperature toughness after PWHT at low temperatures down to -40℃.
It is characterized by welder appeal, with a smooth stable arc, low smoke and spatter levels.
In case of heavy plate welding, preheat at 50~150℃.
