BÖHLER X 70-IG伯乐焊丝

BÖHLER X 70-IG伯乐焊丝

Description
GMAW wire for the welding of high-strength, heat treated, fine-grained constructional steels
with a minimum yield strength of 690 N/mm 2 .
Due to the precise addition of micro-alloying elements X 70-IG wire features excellent ductility
and crack resistance in spite of its high strength.
Good cryogenic impact energy down to -50 °C.
