Description:
Cromarod LDX is a rutile coated "Lean Duplex" type electrode for welding stainless steels such as
LDX 2101, ASTM S32101. The weld metal is low in Mo, making it the preferred choice for
applications where the corrosive media requires this for corrosion resistance, eg. alkaline corrosive
environments. Cromarod LDX could also be used to weld other duplex stainless steels such as ASTM
S32304 and S32003 but it has to be verified that corrosion resistance of the weld metal is sufficent for
the specified application.
