Flux for Submerged Arc welding of General Struct
AMA OP250A
Standards: EN 760: | S A CS 3 97 AC |
DIN 32 522 | B CS 3 97 CCrMo AC8 |
Type/ Characteristics:
Agglomerated alloy-bearing type flux for hard surfacing purposes, to be used in combination with 50-11 wire electrode. 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.
AMA OP 250 A is suitable to be used on either DC or AC.
