Pfeka isingachinji simbi ndiro iplate yesimbi yakakwira-carbon alloy.Izvi zvinoreva kuti Pfeka inodzivirira simbi ndiro yakanyanya kuoma nekuda kwekuwedzera kwekabhoni, uye inoumbwa uye inoshingirira mamiriro ekunze nekuda kwekuwedzerwa alloys.
Carbon yakawedzerwa panguva yekuumbwa kwesimbi ndiro inowedzera kuoma uye kuoma, asi inoderedza simba.Naizvozvo, Pfeka inodzivirira simbi ndiro inoshandiswa mumashandisirwo uko mabrasions uye kupfeka uye kubvaruka ndizvo zvinokonzeresa kutadza, sekugadzira maindasitiri, migodhi, kuvaka uye kubata zvinhu.Pfeka simbi inodzivirira ndiro haina kunaka pakuvaka zvivakwa sematanda ekutsigira mumabhiriji kana zvivakwa.
Musiyano wehunyanzvi pakati peabrasion resistant steel plate ndiyo Brinell Hardness Number (BHN), iyo inoratidza huwandu hwekuoma kwezvinhu.Zvishandiso zvine maBHN akakwira zvine mwero wakakura wekuomarara, nepo zvinhu zvine maBHN akaderera zvine mwero wakaderera wekuoma:
NM360 Wear Resistant Steel Plate: 320-400 BHN Kazhinji
NM400 Wear Resistant Steel Plate: 360-440 BHN Kazhinji
NM450 Wear Resistant Steel Plate: 460-544 BHN Kazhinji
Kupfeka-inodzivirira simbi yemachina ekuvaka, inodiwa kuve nemhando yepamusoro yekuita senge yakakwira kupfeka kuramba, kuomarara kwepamusoro, kupikisa kupikisa, welding nyore, uye nyore kugadzira.Chiratidzo chikuru chekusagadzikana kwekupfeka ndiko kuoma kwepamusoro.Iyo yakakwirira kuoma, zviri nani kupfeka kuramba.
Impact kuramba Sezvo kukanganiswa kwataurwa, iyo NM inomira-inodzivirira simbi ndiro ine yakanaka mhedzisiro kuoma, uye kugona kuramba dents kuri nani zvakanyanya pane kuya kweakajairwa simbi yesimbi kana ichiiswa mukurema.
Ehezve, kusimba kwepamusoro zvakare ndiyo huru yekuita index yekupfeka-resistant simbi.Pasina simba rakakwirira, hapana yakakwira kukanganisa kupikisa uye kuoma.Nekudaro, kunyangwe simba regoho resimbi isingachinjiki richipfuura 1000 MPa, iyo yakaderera-yekushisa kukanganisa kuoma kwe -40 °C inogona kuramba ichisvika kupfuura 20J.Izvi zvinobvumira mota dzemuchina wekuvaka kuti dzishandiswe zvakachengeteka munzvimbo dzakasiyana siyana dzakaomarara.
