Description:
Cromamig 310 is primarily intended for welding the 25% Cr / 20% Ni, type 310, fully austenitic
stainless steels, used for corrosion and oxidation resistance at elevated temperatures. Suitable also
for joining difficult-to-weld steels such as armour plate and ferritic stainless steels as well as dissimilar
steels.
