For Stainless Steels Alloys

LoTherme-409M

AWS: SFA

EN ISO CODE:

Low heat input stainless steel electrode for similar and
dissimilar applications.

Approvals

Characterstics

• Quiet and stable arc, which is easy to strike and
re-strike.
• A highly crack-resistant weld deposit that
displays good corrosion and scaling resistance.
• Weld metal withstands high temperatures up to
1200oC
• On horizontal fillet welds, produce more of a spray
arc and arc and finner rippled weld bead.
• The weld metal is of radiographic quality.
• Electrode can be used in horizontal, vertical up,
and overhead positions.
• Detachability of slag is very easy.

Applications

For repairing stainless steel of similar composition in wrought or cast form, and
for overlay application to resist heat and corrosion. Suitable for repair & joining
dissimilar steels, such as 18-11-Mo steel to mild steel, clad side welding of 18-11-
Mo steel, and for buffer layer applications.

Typical Mechanical Properties

Ultimate Tensile Strength: 570 MPa

Elongation (L=4d): 35%

Welding Techniques

Ensure the electrodes are dry and in case of moisture pick-up, re-dry the
electrodes at 300-350°C for 01 hour. Ensure cleanliness of the weld area and use
short arc, the lowest current possible, and stringer beads.
