AMA OP350A	Product Name:
B CS 3 97 CCrMo AC 8	DIN32 522:
SA CS 3 97 AC	EN 760:

Type/characteristics:
Agglomerated alloy-bearing type flux for hard surfacing purposes, to be used in combination with 50-11, 50-22 wire electrodes. The alloying effect of the flux depends to a large degree on the welding parameters chosen. Optimum parameters for a 4 mm dia. Wire electrode are 600A/32V/50cm/min. welding speed. AMA-OP350 A is suitable to be used on either DC or AC.

Damp flux shall be redried by baking at 300°C.
