Description:
Elgacore M690 is a metal cored wire suitable for welding high-strength low-alloy steels with a
minimum yield strength of 700 MPa. It operates with Ar/CO2 shielding gas, and produces a stable
arc with the typical deep and wide penetration that is found on metal cored products. The wire is
CTOD tested.
Applications:
Jack-up rigs, truck chassis, cranes, earthmoving machines, extended excavator booms, bridges,
flood gates and penstocks.
