Cromamig 307Si produces a tough, ductile, 19% Cr / 9% Ni / 7% Mn austenitic stainless weld metal
which is highly crack resistant. 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 Cromamig 307Si
can be PWHT without risk of sigma-phase formation and consequent loss of ductility. The deposit
work hardens from 200 HV to 450 HV.
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.
