Electrodes for Creep Resisting Steels
CROMOTHERME-24
AWS: SFA 5.5 E9015-B24
EN ISO CODE:
* A stable and steady arc which is easy to strike and re-strike. * Easy slag removal and finely rippled smooth beads. * Weld metal of having lesser impurities i.e. S, P will improve the subzero impact property. * The electrode is used for welding similar composition materials and SA-182, F22V SA-336, F22V & SA-541, 22V. * Specially applicable wherever prolonged heat treatments cycles are involved. * Basically it is used for fabricating desulphurization reactors, heavy section pressure vessels having similar composition.
