TFY-LIT S1 COBART BASED ALLOYS
Features:
TFY-DMTÂ S1 deposits a cobalt base alloy with an austenitic-ledeburitic structure. It is the hardest of the standard cobalt base alloys. It shows a great resistance to corrosion, especially to reducing acids, impact, extreme wear and temperature shocks. The alloy is only machineable by grinding.
Application:
Wear pads, rotary seal rings, pump sleeves; centre less grinder work rests, etc.
