Description:
Elgacore R690 is a all-positional rutile flux cored wire suitable for welding high-strength low-alloy
steels with aminimum yield strength of 700 MPa. The wire operates with a stable arc to produce good
weld bead apearance, easy slag removal and excellent fracture toughness at temperatures down to
–40°C.
