Valve at shaft Surfacing Welding Electrodes D507

MGA APLIKASYON:

Ginagamit ito para sa mga cladding shaft at valve ng carbon steel o alloy steel na ang temperatura sa ibabaw ay mas mababa sa 450 °C.

MGA KATANGIAN:

Ang D507 ay isang surfacing electrode na may mababang hydrogen sodium coating.

Ang surfacing metal ay 1Cr13 semi ferrite high chromium steel.

Ang hardfacing layer ay may mga katangian ng air quenching, sa pangkalahatan ay hindi nangangailangan ng heat treatment,

at ang katigasan nito ay pare-pareho, at maaari rin itong maging annealing-softing sa hanay na 750°C -800°C .

Dual purpose, magandang proseso ng welding.Pinainit sa 900-1000°C, maaari itong muling tumigas pagkatapos ng air cooling o oil quenching.

Available ang DC reverse connection.
