Hardfacing WeldingI-Electrode
Umgangatho: DIN 8555 (E1-UM-350)
Uhlobo lweNombolo: TY-C DUR 350
Inkcazo kunye nesicelo:
· I-electrode ye-SMAW eqatyiweyo esisiseko yokuqhekeka kunye nokunxiba i-surface resistant.
· Ukumelana kakuhle nokukrazuka.Kulula ukuwelda kuzo zonke izikhundla.
· Ifaneleke ngokukodwa ukunxitywa kwe-surfacing ekwaziyo ukumelana ne-Mn-Cr-V alloyed parts, njengamasele, ii-track rollers, i-chain support rolls, i-sprocket wheels, i-guide rolls njl.njl.

Iimpawu eziqhelekileyo:
· Microstructure Ferrite + Martensitic
· Machinability Good nge Tungsten carbides tips izixhobo
· Ukufudumeza kwangaphambili Ukufudumeza iindawo ezinzima kunye neentsimbi ezinokuqina okuphezulu ukuya kwi-250-350 ℃
· Ukwenza i-Redry ye-2 h kwi-300℃ phambi kokusetyenziswa.
