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.
