for cast steel (except creep resistance and high alloy steels) you can very well use E7018 type of electrodes without any problem
Heat the job up to 250 0C
weld with 7018 do not allow the inter pas temp within 250 to 300 0 C electrodes should be redryed up to 150 0C
for creep resistance steel 8018 or 9018G will worbetter
