Classification:
EN ISO 3581-A E 18 8 Mn R 53
AWS A5.4 ~E 307-26
Description:
Elgaloy Mix 18 is a rutile-coated, 160% recovery electrode of the 307 type, intended for joining and
building up 13% Mn steels and welding armour plate 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. In contrast to Elgaloy Mix 29, welds produced with Elgaloy Mix 18 can be stress-relieved
without risk of sigma-phase formation and consequent loss of ductility. The deposit work hardens from
200 HV to 450 HV. Also available as a self-shielded flux cored wire, Elgaloy Mix 18 R.
Applications:
Buffer layer on 13% Mn steels used in rock crushing and earth moving equipment prior to surfacing
with Elgaloy 100, and also rails, rail crossings, frogs etc. without preheat.
