FERROMATIC

APPLICATIONS/ PROPERTIES:

Heavy coated rutile high- efficiency electrodes with

160% metal recovery. Suitable for container and

storage vessel construction, filler and capping

runs of multi- layer weldments. Good notch

toughness, automatic striking and re- striking,

bead can be drawn out. Excellent deslagging

characteristics.
