Description:

Cromarod 253 is a special rutile flux coated electrode designed for high temperature stainless steels

of similar composition used at temperatures up to 1150 °C. The electrode is made on a fully alloyed

core wire and deposits a 0.06%C / 22%Cr / 10.5%Ni / 0.17%N weld metal, microalloyed with the rare

earth metal cerium to give stable high temperature mechanical and oxidation properties. Cromarod

253 runs with a low spatter arc to produce a smooth weld bead finish, easy slag detachability and

particularly good vertical-up operability.
