12L14 Tšepe e sehang mahala

A tšepe e nang le sebabole le phosphorus tse fetang tse tloaelehileng tse reretsoeng ho etsa likarolo tsa lisebelisoa tsa mochini tse iketsang ka lebelo le phahameng le tse iketsang ka semiautomatic. Tšepe e sehang ka bolokolohi e hlahisoa ka mokhoa oa lithupa, 'me e na le 0.08–Khabone ea 0.45 lekholong, 0.15–0.35% ea silicon, 0.6–Karolo ea 1.55 lekholong ea manganese, 0.08–Karolo ea 0.30 lekholong ea sebabole, le 0.05–Fosforose ea 0.16 lekholong. Sekhahla se phahameng sa sebabole se lebisa ho thehoeng ha lintho tse kenyellelitsoeng (mohlala, manganese sulfide) tse lahliloeng hammoho le lijo-thollo. Lintho tsena tse kenyellelitsoeng li nolofalletsa ho beola le ho khothalletsa ho sila le ho thehoa ha chip habonolo. Bakeng sa merero ena, tšepe e sehang ka bolokolohi ka linako tse ling e kopanngoa le loto le tellurium.

12L14 ke mofuta oa tšepe ea khabone e tsosolositsoeng le e nchafalitsoeng bakeng sa lits'ebetso tsa ho seha le ho sebetsa ka machining. Tšepe ea sebopeho (Tšepe e iketsang) e na le bokhoni bo botle ba ho sebetsa ka machining le matla a tlase ka lebaka la likarolo tsa ho kopanya tse kang Sulfur le Lead, tse ka fokotsang khanyetso ea ho seha le ho ntlafatsa qetello le ho nepahala ha likarolo tse entsoeng ka machining. Tšepe ea 12L14 e sebelisitsoe haholo tlhahisong ea likarolo tsa lisebelisoa tse nepahetseng, likarolo tsa likoloi le likarolo tsa bohlokoa tsa mefuta e fapaneng ea mechini, lits'ebetso tse tloaelehileng ho kenyeletsoa li-bushings, shafts, inserts, couplings, fittings le jj.
