Description:
Cromarod 310 is a rutile coated electrode primarily intended for welding the 25%Cr / 20%Ni, type
310, fully austenitic stainless steels, used for corrosion and oxidation resistance at elevated
temperatures. Cromarod 310 can also be used to join difficult-to-weld steels such as armour plate
and ferritic stainless steels, as well as dissimilar steels. Although the weld metal is fully austenitic the
composition has been carefully balanced to give good resistance to hot cracking.
