TIG Rods MTC MT-904L 1.4519

Welding rod/wire electrode made of copper-bearing, fully austenitic chromium-nickel-molybdenum steel with high molybdenum and extra-low carbon content for TIG or MIG/MAG welding of high-alloy steels with increased corrosion resistance against reducing media. Weld metal for operating temperatures up to +350°C.

Special Notes

Cleanliness of the workpiece in the weld seam area is a prerequisite for a crack-free connection. Interpass temperature maximum +150°C.

TIG - Aim for the largest possible seam cross-section in the root pass and prevent overheating of the weld pool by adding sufficient welding rod material.

MIG/MAG - preferably weld with a pulsed arc.
