Description:

Cromarod 309MoLP is a fully-positional rutile flux coated electrode

specially designed for applications requiring optimum positional operability. The high alloy content

and ferrite level enables the weld metal to tolerate dilution from dissimilar and difficult-to-weld

materials without hot cracking.The relatively thin coating and fast-freezing slag makes Cromarod

309MoLP particularly suitable for welding dissimilar joints of differing thicknesses e.g. 4 mm stainless

to 7 mm medium carbon steel.

Applications:

- Dissimilar joints between stainless and mild, low or medium cartbon steels.

- Joining of medium carbon hardenable steels, e.g. armour plate.
