440a 440b 440c Chemical vaega:
| Vasega | 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 |
| 440c | 0.95 - 1.20 | ≤1 | ≤1 | ≤0.030 | ≤0.040 | 16.00 ~ 18.00 | - | ≤0.75 |
O le carbon anotusi ma le malosi o 440-440b-440c faʻateleina mai ABC (A-0. 0.75%, B-0,9%). O le 440c o se sili sili ona lelei maualuga-pito o le shinless steel ma le malosi o le 56-58 rc. O nei fitwels e tolu e lelei le malosi, 440 o le sili sili ona lelei, ma o le 440c o le pito sili ona maualalo. O le 440c e taatele. O le vailaʻau o loʻo tuʻufaʻatasia o le faamatuu atu o le stensiplec steal e pei o le faʻaopopoina o mea e pei o le molybdeanum, tanoa, vanisium,-nr) Talu mai le fale o le taʻele o se tino-ogatotonu o le pabilic fausaga, o le malosi e pa'ū ma le sili ona vevela i le vevela vevela. Lalo 600 ° C, o le maualuga maualuga o le lauʻeleʻele o le maualuga lea o ituaiga uma o slingless Swel, ma le Hurp Weace o sili foʻi lenei. 440 o le sili atu le faʻafefeina ma le faʻamavaia meatotino ma le maualuga malosi. E maualuga le faigata nai lo le 440B Steel ma 440c Steel. O loʻo faʻaaogaina 440B mo le tipiina o meafaigaluega, faʻatau mea faigaluega, fananau meafaigaluega ma vatila. E sili atu le maualuga maualuga nai lo 440a Steel ma maualuga le faigata nai lo 440c steel. O le 440c ei ai le mamafa sili o le slevant beebless sweel ma vevela-tetee atu steeb ma ua faʻaaogaina mo ni auvae ma ni a busa. 440f o se Swel Groent vasega e faʻaleleia ai le faigofie-tipi meatotino o 440c Steel mo otometi Lathes.
