Raws li GB / T 983-1995 "stainless steel electrode" tus qauv, stainless hlau electrode tuaj yeem muab faib ua chromium stainless hlau electrode thiab chromium-nickel stainless hlau electrode ob pawg.
(1) Chrome stainless hlau electrode
Qhov zoo ntawm vuam pas nrig feem ntau muaj Crl3 series stainless hlau electrode thiab Crl7 series stainless hlau electrode. Vuam yam ntxwv ntawm ob series ntawm electrodes tau piav qhia hauv qab no:
1) Cr13 series stainless hlau electrode: xws li G202, G207, G217 thiab lwm yam electrodes yog martensitic stainless hlau Cr13 series electrode, nrog rau no series ntawm stainless hlau vuam martensitic stainless hlau, lub weldment yuav tsum tau preheated ua ntej welding ntau tshaj 300 degree, Tab sis kuj tom qab vuam cov vuam yuav tsum tau nqa tawm ntawm 700 degree tempering, thiab tsuas yog ua raws li cov txheej txheem saum toj no, txhawm rau kom tsis txhob vuam thiab kub cuam tshuam rau thaj tsam vim muaj kev nyiam ntau dua rau kev tawg thiab tawg.
2) Cr17 series stainless hlau electrode: xws li G302, G307 thiab lwm yam electrodes yog ferritic Cr17 series stainless hlau electrode, nrog no series ntawm stainless hlau vuam ntawm ferritic stainless hlau, lub vuam yuav tsum tau preheated ua ntej vuam 200 degree, thiab vuam tom qab lub weldment tab sis kuj mus rau 800% ntawm tempering, thiab tsuas yog ua raws li cov txheej txheem saum toj no ntsuas, thiaj li tsis txhob weld thiab tshav kub cuam tshuam cheeb tsam 475 degree embrittlement thiab zoo li tawg vim muaj ntau dua nyiam harden.
(2) chrome-nickel stainless hlau electrode
Xws li cov electrodes muaj qhov zoo corrosion kuj thiab oxidation tsis kam, tab sis, vim rov ua cua sov hauv cov txheej txheem vuam, nag lossis daus ntawm carbide yuav txo cov corrosion kuj thiab txhua yam khoom, yog li kev xaiv ntawm chrome-nickel stainless hlau electrode, vuam yuav tsum tau txiav txim siab qhov chaw. ntawm kev ua hauj lwm kub thiab media hom.
