CrMo Alloys for Power Generation

Section 1 – Low Alloy Steels

This section includes electrodes suitable for welding general engineering and structural steels of every type, from medium tensile grain-refined CMn and semi-cryogenic steels (approximately –75°C) to specialised heat and creep-resistant CrMo types reaching the threshold of stainlessness at 12%Cr. Flux coverings of all electrodes are of all-positional basic low-hydrogen type and employ binders giving high resistance to moisture absorption. All flux cored wires are rutile all-positional types also with low hydrogen potential.

A comprehensive range of filler materials to meet industry needs for the welding of CrMo low alloy steels used in power generating plant. Metrode has an established track record of supply to the power generation industry worldwide. The consumables have been developed to meet the stringent requirements for long term high temperature performance required for modern power generating plant.
