Kuʻi paʻakikīElectrode
Kūlana: DIN 8555 (E7-UM-250-KPR)
ʻAno ʻAno: TY-C BMC
Hōʻike a me ka noi:
· Kākoʻo kumu hoʻōla kiʻekiʻe SMAW electrode
· Hoʻolālā austenite piha.Kiʻekiʻe loa ka paʻakikī hana a me ka paʻakikī kiʻekiʻe.
· He kūpono ia no nā pale ma nā ʻāpana i pili i ke kaomi kiʻekiʻe a me ka haʻalulu i hui pū ʻia me ka abrasion.Hiki ke hana ʻia ka ʻili ma luna o ke kila ferritic a me ka austenitic hard Mn-steel a hiki ke wili ʻia nā hui o Mn-steel paʻakikī.
· Aia nā kahua noi nui i ka ʻoihana mining a me ka ʻoihana sima, ke ala kaʻaahi, nā dredge pumps, hydraulic press pistons, crusher part undergoing high impact by soft mineral.
