Hardfacing WeldingI-Electrode
Umgangatho: DIN 8555 (E9-UM-250-KR)
Uhlobo lweNombolo: TY-C65
Inkcazo & nesicelo:
· I-electrode ekhethekileyo ene-welding efanelekileyo kunye neempawu zomatshini.
· Austenite- Ferrites weld metal.Amaxabiso anamandla aphezulu kunye nokumelana nokuqhekeka okuphezulu.
· Ifaneleke ngakumbi ukudibanisa kwiintsimbi ezingenakuweldable, xa iimfuno eziphezulu kwi-welding seam zenziwe.
· Ukumelana nokuqhekeka okuphezulu xa kudityaniswa neentsimbi zabazali ezinobunzima bokuwelda, ezifana neentsimbi ze-austenitic kunye ne-ferritic, iintsimbi eziphezulu ze-manganese ezinealloyidi kunye nezingafakwanga iintsimbi, eziphathwa ngokushushu kunye neentsimbi zesixhobo.Izicelo ekulungiseni nasekugcinweni komatshini kunye namacandelo okuqhuba kunye nokulungiswa kwezixhobo.
• Njengomaleko womqamelo kwezi mathiriyeli nawo ufanelekile ngokufanelekileyo.
Ukwakheka kweekhemikhali zentsimbi egciniweyo(%):

Iimpawu eziqhelekileyo:
· Microstructure Austenite + Ferrite
· Ukusebenza ngokugqwesileyo
· Ukufudumeza kwangaphambili Ukufudumala kweendawo ezityebileyo ezinodonga lwe-ferritic ukuya kwi-150-150 ℃
· I-Redrying ye-2 h kwi-150-200 ℃ phambi kokusetyenziswa.
