Aisi 440a, Un CE S44002, JIS SUS440A, W.-NR. 1.4109 (Din x70crmo15) lembaran stainless steel, piring, flat
Aisi 440B, Un CE S44003, jis sus440b, W.-NR. 1.4112 (DIN X90RMOV18) lembar stainless steel, piring, flat
Aisi 425C, Un CE S44004, JI SUS440C, W.-NR. 1.4125 (din x105crmo17) lembaran stainless steel, piring, flat
440A 440B 440C CAM (440C):
| Kelas | 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 |
Konten karat lan kekerasan 440A-440B-440C saya sukses saka ABC (A-0.75%, B-0.9%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1%, C-1,2%, 440C minangka baja stainless steel kanthi dhuwur kanthi atose 56-58 RC. Telung steels iki duwe tahan karat sing apik, 440A paling apik, lan 440C paling murah. 440C umum banget. Komposisi kimia baja tahan karat martensitis ditondoi kanthi tambahan unsur kayata molybdenum, tungsten, vanadium, lan niobium adhedhasar macem-macem komponen 0,1% -2,0,0% C lan 12% -2 -2% Kr. Wiwit struktur jaringan minangka struktur kubik sing fokus ing awak, kekuwatan kasebut mudhun kanthi suhu sing dhuwur. Ing ngisor iki 600 ° C, kekuatan suhu dhuwur paling dhuwur ing antarane kabeh jinis stainless steel, lan kekuatan creep uga paling dhuwur. 440A duwe sifat quenching sing apik lan hardening lan kekerasan. Nduwe kekarepan sing luwih dhuwur tinimbang baja 440B lan baja 440C. 440B digunakake kanggo alat nglereni, ngukur alat, bantalan lan katup. Wis luwih angel tinimbang baja 440A lan kekarepan sing luwih dhuwur tinimbang baja 440C. 440C duwe atose paling dhuwur ing kabeh stainless steel lan baja tahan panas lan digunakake kanggo muncung lan bantalan. 440f minangka bahan baja sing nambah sifat-sifat baja sing gampang dipotong kanggo lathes otomatis.
