12L14 Ibha Yensimbi Esikayo Yamahhala

A insimbi enokuqukethwe okuphezulu kwesibabule ne-phosphorus okungaphezu kokujwayelekile okuhloselwe ukwenziwa kwezingxenye zamathuluzi omshini ozenzakalelayo kanye ne-semiautomatic enesivinini esikhulu.Insimbi yokusika mahhala ikhiqizwa ngendlela yezinduku, futhi iqukethe i-0.08-0.45 amaphesenti carbon, 0.15-I-silicon yamaphesenti angu-0.35, i-0.6-I-1.55% ye-manganese, 0.08-0.30 iphesenti sulphur, kanye 0.05-0.16% phosphorus.Okuqukethwe okuphezulu kwesibabule kuholela ekwakhekeni kwezinto ezifakiwe (isibonelo, i-manganese sulfide) ezilahlwa eduze nokusanhlamvu.Lokhu kufakwa kusiza ukugunda futhi kukhuthaze ukugaya kanye nokwakheka kalula kwe-chip.Ngenxa yalezi zinhloso, insimbi yokusika mahhala ngezinye izikhathi ihlanganiswe nomthofu kanye ne-tellurium.

I-12L14 iwuhlobo lwensimbi yekhabhoni esulfurized ne-rephosphorized for free-cut and machining application.Insimbi yesakhiwo (i-automatic Steel) inokusebenziseka okuhle kakhulu namandla aphansi ngenxa yezakhi ze-alloying njengeSulfur neLead, enganciphisa ukumelana nokusika futhi ithuthukise ukuqedwa nokunemba kwezingxenye zomshini.Insimbi ye-12L14 isetshenziswe kabanzi ekwenzeni izingxenye zensimbi ezinembayo, izingxenye zemoto kanye nezingxenye ezibalulekile zezinhlobo ezahlukene zemishini, izinhlelo zokusebenza ezijwayelekile ezihlanganisa ama-bushings, shafts, inserts, couplings, okokufaka nokunye.
