Description:

Elgaoly Mix 18B is an all positional basic-coated electrode which deposits a 19% Cr / 9% Ni / 6% Mn

fully austenitic stainless steel weld metal with excellent toughness and crack resistance. It is intended

for joining hardenable steels, armour plate, 13% Mn steels and difficult-to-weld steels, without the

need for preheat. It is also recommended for dissimilar joints between stainless and mild or medium

carbon steels. Welds produced with Elgaloy Mix 18B can be PWHT without risk of sigma-phase

formation and consequent loss of ductility. The deposit work hardens from 200 HV to 450HV.

Applications:

Buffer layers on 13% Mn steels used in rock crushing and earth moving equipment, prior to

hardfacing. Reclaiming 13% Mn steels. Surfacing of rails, rail crossings, frogs etc. Buffer layers in

highly restrained repair work.
