Low-alloyed Electrodes
ES 11018 GW A5.5: E 11018-G / EN 757: E 75 6 CrMoV B 42 H5
Description
ES 11018 -GW Application Fields and Properties hot work tool steels and 550-600 ° c as well as high operating temperatures similar to the origin of the alloy steel casting is an electrode used in alkaline type. Cr, Mo, V, W that contains light-alloy steels and hot work steels are suitable to the source. Hot work steel during hardfacing and wear-resistant surface coating of sources can also be used. Interpass temperatures and front tav, tav operation according to metal to be welded the last main should be determineddir according to base metal.
