ASTM A 128 Gr. B-1 is High Manganese cast steel with 11.5 to 14 % Mn,
C & Si under 1.0 %.You have not mentioned whether it is hard surfacing or
repairing of broken casting.
Austenitic Mn steels with 14% Mn (also known as Hadfield steels) have a tendency
to form brittle precipitates in the form of carbides. It is essential to weld without
preheating, even with additional cooling and keep the specific heat input low.
E 312-16 with 30 Cr & 10 Ni will be ideal It has two phase structure with substantial amount of ferrite in austenitic matrix. Weld metal is highly resistant to weld metal
cracks and fissures.
