Umehluko phakathi kwensimbi yokusika yamahhala engu-1215 nensimbi engu-11SMn30

Insimbi yokusika yamahhala ibhekisela kunsimbi ye-alloy enezela inani elithile lesici esisodwa noma ngaphezulu sokusika mahhala njengesulfure, i-phosphorus, i-lead, i-calcium, i-selenium, i-tellurium, njll ukuze kuthuthukiswe ukusebenza kwayo.Ngokuzenzakalelayo, isivinini esikhulu kanye nokunemba kokusika, kubaluleke kakhulu ukudinga insimbi ukuze ibe ne-machinability enhle, esetshenziselwa ikakhulukazi ukucubungula emshinini wokusika othomathikhi.Okulandelayo kugxile kumehluko phakathi kwensimbi yokusika yamahhala engu-1215 kanye nensimbi yokusika yamahhala engu-11SMn30.

1215 Insimbi Yamahhala Yokusika

I-1215 iwuhlobo lwensimbi yokusika elula ochungechungeni olujwayelekile lwe-ASTM/AISIBI.Insimbi yokusika yamahhala engu-1215 iyinto evumelana nemvelo engaqukethe umthofu noma izinto eziyingozi emvelweni.Inezici ezinhle zokusika futhi ifanele ama-electroplating shafts jikelele, izinto zokusika, nezingxenye ezijwayelekile.

Ububanzi obusebenzayo

Insimbi yokusika yamahhala engu-1215 isetshenziswa ikakhulukazi ekukhiqizeni amathuluzi, izingxenye zewashi, izimoto, amathuluzi omshini, neminye imishini ehlukahlukene enezidingo eziqinile zosayizi nokushelela ngenxa yengcindezi ephansi.Inezidingo eziqinile zokunemba kosayizi nobushelelezi, kodwa izidingo eziphansi uma kuqhathaniswa zezakhiwo zemishini, njengamagiya, shafts, amabhawodi, amavalvu, amabhushi, izikhonkwane, amalunga epayipi, amakhushini ezihlalo zasentwasahlobo nezikulufu zamathuluzi omshini, isikhunta esakha ipulasitiki Izinqubo zokuhlinza nezamazinyo. , njll.

11SMn30 insimbi yokusika yamahhala

I-11SMn30 (1.0715) iyizinga laseJalimane elijwayelekile lokusika lamahhala, okungeyesulphur phosphorus composite high sulfur, low silicon free cutting structural steel.

Ububanzi obusebenzayo

I-11SMn30 (1.0715) insimbi yokusika yamahhala ivame ukusetshenziswa ekwenzeni izingxenye ezingabalulekile ezijwayelekile, njengamabhawudi, amantongomane, amalunga epayipi, izihlalo zasentwasahlobo, njll.

I-Gapower Metal entshaungumkhiqizi wensimbi wokusika wamahhala.Imikhiqizo eyinhloko ihlanganisa 1212 1213 1214 1215 1140 1144 12l13 12l14,12l15 11SMn30 njll. Amakhasimende angathola lonke uhlobo lweshubhu abeludinga.
