12L14 Sebaka sa tšepe se sehang mahala

A tšepe e nang le sebabole le phosphorus tse nang le lintho tse phahameng ho feta tse tloaelehileng tse reretsoeng ho etsa likarolo tsa lisebelisoa tsa mochini o itekanetseng le oa semiautomatic. Tšepe e sa lefelloeng e hlahisoa ka mokhoa oa lithupa, 'me e na le 0.08-0,45 lekholong carbon, 0,15-0,35 lekholong silicon, 0,6-1,55 lekholong manganese, 0,08-0.30 lekholong sebabole, le 0.05-0,16 lekholong ea phosphorus. Lintho tse ngata tsa sebabole li lebisa ho thehoeng ha li-inclusions (mohlala, manganese sulfide) tse lahliloeng haufi le lijo-thollo. Likakaretso tsena li thusa ho kuta le ho khothaletsa ho sila le ho theha chip ha bonolo. Bakeng sa merero ena, tšepe e sa lefelloeng ka linako tse ling e kopantsoe le lead le tellurium.

12L14 ke mofuta oa tšepe ea k'habone e entsoeng ka resulfurized le rephosphorized bakeng sa lisebelisoa tsa mahala tsa ho itšeha le tsa machining. Mohaho oa tšepe (automatic Steel) o na le machinability e babatsehang le matla a tlaase ka lebaka la likarolo tsa alloying tse kang Sulfur le lead, tse ka fokotsang ho hanyetsa ho itšeha le ho ntlafatsa qetello le ho nepahala ha likarolo tse entsoeng ka mochine. 12L14 tšepe e sebelisitsoe haholo ha ho etsoa likarolo tsa lisebelisoa tse nepahetseng, likarolo tsa koloi le likarolo tsa bohlokoa tsa mefuta e fapaneng ea mochini, lits'ebetso tse tloaelehileng tse kenyelletsang lihlahla, li-shafts, li-insert, li-couplings, li-fittings joalo-joalo.
