Umahluko phakathi kwentsimbi yokusika yamahhala 1215 kunye ne-11SMn30 yentsimbi

Insimbi yokusika yamahhala ibhekisela kwinsimbi ye-alloy eyongeza inani elithile okanye ngaphezulu kwezinto zokusika zamahhala ezifana ne-sulfure, i-phosphorus, i-lead, i-calcium, i-selenium, i-tellurium, njl.Ngokuzenzekelayo, isantya esiphezulu kunye nokuchaneka kokusika, kubaluleke kakhulu ukufuna intsimbi ukuba ibe ne-machinability efanelekileyo, esetyenziselwa ngokukodwa ukuqhutyelwa kumatshini wokusika ngokuzenzekelayo.Oku kulandelayo kugxininise kwiiyantlukwano phakathi kwe-1215 yensimbi yokusika yamahhala kunye ne-11SMn30 yensimbi yokusika yamahhala.

1215 Intsimbi yokusika yasimahla

I-1215 luhlobo lwentsimbi yokusika elula kwi-American ASTM / AISIBI uchungechunge oluqhelekileyo.I-1215 insimbi yokusika yamahhala yinto ehambelana nokusingqongileyo engenalo i-lead okanye izinto ezinobungozi kwindalo.Ineempawu ezintle zokusika kwaye ifanelekile i-electroplating shafts jikelele, izinto zokusika, kunye neendawo eziqhelekileyo.

Umda osebenzayo

I-1215 yentsimbi yokusika yasimahla isetyenziswa ikakhulu kwimveliso yezixhobo, iinxalenye zokubukela, iimoto, izixhobo zoomatshini, kunye nabanye oomatshini abahlukeneyo abaneemfuno ezingqongqo zobukhulu kunye nokugudiswa ngenxa yoxinzelelo oluphantsi.Ineemfuno ezingqongqo zokuchaneka kobungakanani kunye nokugudiswa, kodwa iimfuno eziphantsi ngokwentelekiso kwiipropathi zoomatshini, njengeegiya, iishafti, iibholiti, iivalvu, iibhuqe, izikhonkwane, iintambo zombhobho, imiqamelo yesihlalo sasentwasahlobo kunye nezikrufu zesixhobo somatshini, ukubumba iplastiki yokubumba Iinkqubo zotyando kunye namazinyo. , njl.

11SMn30 intsimbi yokusika yasimahla

I-11SMn30 (1.0715) kumgangatho waseJamani wokusika ibakala lentsimbi, eyesulfure phosphorus edityanisiweyo nesulfure ephezulu, i-silicon ephantsi yokusika intsimbi yesakhiwo.

ukwakheka kweekhemikhali

Umda osebenzayo

I-11SMn30 (1.0715) insimbi yokusika yamahhala isetyenziswa ngokuqhelekileyo ekwenzeni iindawo ezingabalulekanga eziqhelekileyo, ezifana ne-bolts, nuts, joint joints, izihlalo zasentwasahlobo, njl.

Intsimbi entsha yeGapowerngumvelisi wentsimbi yokusika yasimahla.Iimveliso eziphambili zibandakanya 1212 1213 1214 1215 1140 1144 12l13 12l14,12l15 11SMn30 njl.
