Valve sy shaft Surfacing welding Electrodes D507

FAMPIASANA:

Izany dia ampiasaina amin'ny cladding shafts sy valves ny karbaona vy na firaka vy izay surfacing mari-pana dia ambany 450 ° C.

TOETRA:

D507 dia electrode surfacing amin'ny ambany hydrogène sodium coating.

Ny metaly ambony dia 1Cr13 semi ferrite avo chromium vy.

Ny sosona hardfacing manana ny toetra ny rivotra quenching, amin'ny ankapobeny tsy mila hafanana fitsaboana,

ary ny hamafiny dia mitovy, ary mety ho annealing-fanalefahana amin'ny isan-karazany ny 750 ° C -800 ° C.

tanjona roa, dingana welding tsara.Nafanaina hatramin'ny 900-1000°C, azo averina hamafisina aorian'ny fampangatsiahana ny rivotra na ny famonoana menaka.

Misy fifandraisana DC mivadika.

toeran'ny welding:PA, PB

FAMPIANARANA FAMPIANARANA (SCORE KALITAO): %
