Abramang Mn
Exceptional impact resistance
Product description
Rutile-base electrode for hardfacing all parts generally subject to very high impact loads. Sometimes used (as a replacement for 18/8 Mn) for the assembly of 13% Mn steels (Hadfield steels). Very interesting as an underlay before hardfacing, when high thicknesses need to be deposited! Allows you to restore the desired volume to the part, then finish the hardfacing with one or two passes of HBA or HB 63. The fully austenitic deposit is exceptionally resistant to impact and wear, thanks to its work-hardening properties. The hardness of the deposit thus obtained rises from 200-250 Brinell (in the as-welded state), to 400-500 Brinell (after work-hardening). The Nickel and Chromium present greatly increase resistance to cracking and abrasion.
Main applications:
Repair of worn parts or protection of new parts. Railway industry (rails, frogs, switches), quarries and mines (crusher jaws, dredger buckets, beaters, waste treatment, wood and stone crushers, armor plating, etc.).
