J506R
Description:
J502NiCu titanium calcium type coating of low alloy weathering electrode. AC and DC dual-use, can be all-position welding. Has excellent welding performance and mechanical properties, stable arc, spatter, easy slag removal; weld appearance, deposited metal has good resistance to atmospheric corrosion.
use:
Mainly used for weathering of the railway rolling stock welding, such as 09MnCrPTi and so on.
