440A 440B 440C Siv Tshuaj Tiv Thaiv:
| Teem nqi | C | Si | Mn | S | P | Cr | Ni | Mo |
| 440A | 0.60 ~ 0.75 | 15 xyoos | 15 xyoos | I≤0.030 | I≤0.040 | 16.00 ~ 18.00 | - | I≤0.75 |
| 440B | 0.85 ~ 0.95 | 15 xyoos | 15 xyoos | I≤0.030 | I≤0.035 | 16.00 ~ 18.00 | I≤0.60 | I≤0.75 |
| 440C | 0.95 - 1.20 | 15 xyoos | 15 xyoos | I≤0.030 | I≤0.040 | 16.00 ~ 18.00 | - | I≤0.75 |
Cov pa roj carbon cov ntsiab lus thiab Hardness ntawm 440A-440B-440C nce kev vam meej ntawm ABC (A-0.9%, C-1.2%). Lub 440C yog qhov zoo heev siab loj stainless hlau nrog lub hardness ntawm 56-58 rc. No peb cov hlau muaj cov xeb zoo, 440A yog qhov zoo tshaj plaws, thiab 440c yog qhov qis tshaj. Lub 440C muaj ntau heev. Cov tshuaj lom neeg cov tshuaj lom neeg ntawm Martensitic Stainless hlau yog cov yam ntxwv xws li molybdenum, voladium, thiab niobium raws li cov khoom sib txawv ntawm 0.1% C thiab 12% -27% cr. Txij li thaum cov ntaub so ntswg yog lub cev ua ke cov qauv sau lo lus teb, lub zog ua rau poob qis ntawm qhov kub. Hauv qab no 600 ° C, lub zog kub siab yog qhov siab tshaj plaws ntawm txhua hom stainless hlau, thiab lub zog loj yog qhov siab tshaj plaws. 440A muaj cov khoom ua kom zoo tshaj plaws thiab tawv tawv thiab qhov nyuaj. Nws muaj ntau dua tawv dua 440B hlau thiab 440C hlau. 440B yog siv rau kev txiav cov cuab yeej, ntsuas cov cuab yeej, bearings thiab li qub. Nws muaj ntau dua qhov nyuaj dua 440A steel thiab siab dua tawv dua li 440c hlau. Lub 440C muaj qhov hnyav tshaj plaws ntawm txhua tus hlau tsis muaj cua sov thiab cua sov resistant hlau thiab siv rau cov pob zeb no thiab cov kabmob. 440F yog tus qib steel uas txhim kho cov khoom siv yooj yim ntawm 440C cov hlau rau cov lathes tsis siv neeg.
