Description:
Cromarod 318 is a niobium stabilised, rutile flux coated electrode designed for welding Nb or Ti
stabilised 18% Cr / 12% Ni / 3% Mo austenitic stainless steels type 318. The electrode has good
positional characteristics and produces low spatter levels and good slag detachability. Cromarod 318
is primarily intended for service temperatures above 400 °C an can also be used for 316 material
grades used at elevated temperatures.
