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.
