Litšepe tse chitja tsa 9SiCr tse chesang

9 sicr tšepe ke tšepe e tlaase ea alloy, empa hape hangata e etsa likarolo tsa hlobo tse batang, phello e ntle haholo. E feta chrome steel (Cr2 kapa 9 Cr2) e na le boima bo phahameng le bo thata ebile e na le botsitso bo phahameng ba mocheso. Mantsoe a tšepe a tsoang ho Soviet Union ea mehleng khale ka 9 xc, e kileng ea tsejoa e le 9 crsi steel. Sebopeho le ts'ebetso ka 9 xc li tšoana hantle.
Tlhaloso e tlase ea mocheso
Litlhoko sepakapakeng se sa nke lehlakore kapa sepakapaka se sireletsang mocheso oa sebōpi, mocheso oa preheating oa 700 ~ 80 ° C o ka lekhetlo la pele, nako ea ho tšoara 1. 0 ~ 1.5 h, ea bobeli 850 ~ 900 ° C, 2 min/mm, nako. ea ho boloka mocheso ho boloka mocheso ho 100 ℃ kapa ka tlase ka mor'a lebelo ho fihla ho 1100 ~ 1150 ℃, ho tšoara nako 1.0 ~ 1.5 min/mn. Lokela ho hangata retelehela ea billet ka tshebetso ya ho futhumatsa, junifomo mocheso, ka ho feletseng chesoa. The forging thempereichara 1050 ~ 1100 ° C, a pheta-pheta habeli sefapano ho forging soabisang, ka mor'a forged alloy carbide grade 2 kapa ka tlaase ho moo.
