I-Aisi 440A, UNS S44002, JIS SUS440A, W.NR. I-1.4109 (DIN X70CRMO15) Amashidi ensimbi angenasici, amapuleti, amafulethi
I-Aisi 440B, ubus s44003, JIS SUS440b, W.-NR. 1.4112 (Din X90CRCROV18) Amashidi ensimbi engagqwali, amapuleti, amafulethi
I-Aisi 440C, ANX S44004, JIS SUS440C, W.-NR. 1.4125 (DIN X105CRMO17) Amashidi ensimbi angenasici, amapuleti, amafulethi
440a 440b 440C 440C Chemical Content:
| Khuphuka | C | Si | Mn | S | P | Cr | Ni | Mo |
| 440a | 0.60 ~ 0.75 | ≤1 | ≤1 | ≤0.030 | ≤0.040 | 16.00 ~ 18.00 | - | ≤0.75 |
| 440b | 0.85 ~ 0.95 | ≤1 | ≤1 | ≤0.030 | ≤0.035 | 16.00 ~ 18.00 | ≤0.60 | ≤0.75 |

Okuqukethwe kwekhabhoni nobulukhuni be-440a-440b-440b-440C kukhule ngokulandelana ku-ABC (A-0.75%, B-0.9%, C-1.2%). I-440C iyinsimbi enhle kakhulu engapheli yensimbi ephakeme enobulukhuni be-56-58 RC. Lawa mansimbi amathathu anokumelana okuhle kokugqwala, 440a ahamba phambili, futhi ama-440c aphansi kakhulu. I-440C ivame kakhulu. Ukwakheka kwamakhemikhali kwensimbi engenacala elingenacala kubonakaliswa ngokungezwa kwezinto ezinjenge-molybdenum, i-tungsten, i-vagadium, ne-niobium ngokusekelwe kwinhlanganisela yezakhi ezihlukile ze-0.1% -27% CR. Njengoba ukwakheka kwezicubu kuyisakhiwo esigxile emzimbeni, amandla ehla kakhulu emazingeni okushisa aphezulu. Ngaphansi kuka-600 ° C, amandla aphezulu okushisa aphezulu kakhulu phakathi kwazo zonke izinhlobo zensimbi engenasici, futhi amandla ama-creep nawo aphezulu kakhulu. I-440A inezakhiwo ezinhle kakhulu futhi eziqinisa kanye nobulukhuni obuphezulu. Inobunzima obuphakeme kunensimbi engu-440b nensimbi engu-440c. I-440B isetshenziselwa amathuluzi okusika, amathuluzi okulinganisa, ama-bearings nama-valve. Inobulukhuni obuphakeme kunensimbi engu-440a kanye nobunzima obuphakeme kunensimbi engu-440c. I-440C inobulukhuni obukhulu kunazo zonke zensimbi engenasici kanye nensimbi engasho lutho futhi isetshenziselwa ama-nozzles kanye namabele. I-440F yibanga lensimbi elithuthukisa izakhiwo ezisikiwe ezilula zensimbi engu-440c ye-letset ye-automatic.
