Development prisadochnyh rod for welding vysokoprochnogo cast iron
The Designed composition cast-iron cast rod for gas and arc-metal of the welding strong cast iron on base rod marks A with accompaniment alloying element, contain rare-earth and boron. The Structure welding metal beside surfaces of the seam at the depth before 1,5-2 mms perlite and small area austenite dendrite to orientation. Hereinafter on height of the seam up to line of the fusing in structure dominates perlite. Hardness in this zone forms 229 HB. The Graphite of the globous average value, several small, than basically metal.
