TYPICAL APPLICATION
Production of pieces that require a good performance to abrasion and at the same time a good toughness. Like pots, high density blades, demolition clamps, pieces and plates for O.P equipment, etc.
SOLDERING
It can be sold using the traditional system.
It is recommended to use dry metal flow adequate with the controlled hydrogen.
It is recommended to preheat the soldering zone, use Hilo Autrod 13-29 OK, basic Fluxocord 42/0841 TT Orlikon electrode or similar.
SHAPING
Warm way: should be hot forming and It is recommended to upright in the sense of lamination.
MECHANIZATION AND OXYCUT
Good. Anneal or stabilized following oxycut recommended.
