Valve and shaft Surfaceing Welding Electrodes D507

CODSIGA:

Waxa loo isticmaalaa in lagu xidho ulaha iyo alwaaxyada birta kaarboon ama birta daawaha kuwaas oo heerkulkiisu ka hooseeyo 450 °C.

Tilmaamaha:

D507 waa koronto dulsaaran oo leh daahan haydarojiin hooseeya.

Birta korkeeda waa 1Cr13 birta chromium-ka sare ee semi ferrite.

Lakabka adagi wuxuu leeyahay sifooyinka hawada deminta, guud ahaan uma baahna daaweyn kulayl,

oo engegnaanteedu waa lebbis, sidoo kale waxay noqon kartaa mid jilicsan oo jilicsan inta u dhaxaysa 750 ° C -800 ° C.

Dual ujeedo, habka alxanka wanaagsan.Kuleylka ilaa 900-1000C, dib ayaa loo adkeyn karaa ka dib qaboojinta hawada ama daminta saliidda.

Xiriirka gadaale DC ayaa diyaar ah.

MEELAHA ALXANKA:PA, PB

QAABKA DEPOSIT (QUALITY SCORE): %

HRC:41
