Welding Wire MTC MT-307 1.4370 D200 5kg Spool

Welding Wire MTC MT-307 1.4370 D200 5kg Spool

Description

MTC MT-307 wire electrode made of austenitic chromium-nickel-manganese steel with low carbon content for TIG or MIG/MAG welding of dissimilar steels for operating temperatures up to +300°C; cold-tough down to -120°C.

 

Important base materials for MT-307

 Dissimilar steels (black-white joints); high-carbon and difficult-to-weld steels, manganese hard steel, e.g.

X120 Mn 12 (1.3401); buffer layers for hardfacing; cold-tough nickel steels, e.g. 10 Ni 14 (1.5637), 12 Ni 19 (1.5680)

Special notes for MT-307

In the root pass, aim for the largest possible weld cross-section; prevent overheating of the molten pool by supplying sufficient filler material at the welding rod. Maximum operating temperature for black-white joints is +300°C. For prolonged annealing treatment above +300°C or for operating temperatures above +300°C, nickel-base welding consumables must be used. Weld metal work-hardens during cold deformation. Weld metal is scale-resistant up to +850°C.
