Kusankha kolondola kwa chitoliro chachitsulo chosasunthika

Chitoliro chachitsulo chosasunthika chimapangidwa popanda kuwotcherera ndi njira zotentha zogwirira ntchito monga kugudubuza kotentha kwa perforated. Ngati ndi kotheka, chitoliro chotenthetsera chikhoza kuzizira kwambiri mpaka mawonekedwe omwe mukufuna, kukula ndi magwiridwe antchito. Pakalipano, chitoliro chachitsulo chosasunthika ndiye chitoliro chomwe chimagwiritsidwa ntchito kwambiri pamagawo opanga petrochemical.

GB9948ili ndi zitsulo za chromium molybdenum: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo ndi zina zotero.

GB6479ili ndi kalasi yachitsulo ya chromium molybdenum: 12CrMo, 15CrMo, 1Cr5Mo ndi zina zotero.

GB/T5310ili ndi zitsulo za chromium-molybdenum ndi chromium-molybdenum vanadium zitsulo zakuthupi: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, etc.
