Dab tsi yog 440 stainless hlau?
440 Stainless hlau yog tsev neeg ntawm high-carbon martensitic stainless hlau, paub txog lawv lub siab hardness, thiab zoo heev Retiste tom qab kev kho cua sov.
Nws yog cov cua sov ua kom sov, thiab nws cov khoom sib txawv raws qib (440B, 440C, 440F), uas yog qhov txawv txav los ntawm lawv cov ntsiab lus carbon.
440C, nrog cov ntsiab lus carbon ntau tshaj plaws, yog qhov nyuaj tshaj plaws thiab siv tau ntau tshaj plaws, ua rau nws xaiv cov khoom lag luam nrov thiab cov dej num zoo xws li bearings.
420 vs . 440 C stainless hlau: sib txawv tseem ceeb
| Ntiag tug | 420 stainless hlau | 440C Stainless Hlau |
|---|---|---|
| Tus lej tsis yog | S42000 | S44004 |
| Txoj cai | ASTM A276 / A240 | ASTM A276 / A240 |
| Carbon (c) | 0.15-0.40% | 0.95-1.20% |
| Chromium (cr) | 12-14% | 16-18% |
| Hardness (HRC tom qab quenching) | 48-52HRC | 56-60hrc |
| Tensile lub zog (mpa) | 700-850 | 760-980 |
| Corrosion Kuj | Tswj kav | Siab dua (rau ntau cr thiab c) |
| Kev Kho Cua Sov | Hardenable ntawm 980-1050 degree | Hardenable ntawm 1010-1070 degree |
| Cov Ntawv Thov | Cutlery, kev phais cov cuab yeej siv, axes | Bearings, riam, pwm, valve seem |
Dab tsi yog qhov sib txawv hauv kev tawv tawv ntawm 440C thiab 420 stainless hlau?
440C Stainless hlau tuaj yeem nyuaj dua 420 tom qab kev kho cua sov, ncav tau qhov siab tshaj plaws ntawm rockwell C 60 (HRC 60), thaum 420 feem ntau tau nce siab ntawm HRC 55.
Qhov loj dua hardness ua 440c ntau cov coj tawm tsam tiv taus thiab haum rau kev siv ntxhov siab siab, txawm tias nws tsis nyuaj li 420.
420 cov hlau yog cov kev siv kom zoo dua thiab yooj yim dua rau lub tshuab, ua rau nws tsim nyog rau cov ntawv thov uas Hardness tsis yog thawj qhov ua tau.
Dab tsi qib yog qhov zoo tshaj plaws rau riam tuaj?
Lub 440C muaj cov ntug kev khaws cia zoo dua thiab hnav tsis kam, ua rau nws xaiv qhov zoo tshaj plaws rau cov riam uas kawg.
420, txawm li cas los xij, yog pheej yig dua thiab yooj yim dua rau Polish.
420 thiab 440C cov hlau yuav welded?
Vuam ntawm ib qho tsis pom zoo vim kev pheej hmoo ntawm kev tawg.
Yog tias yuav tsum muaj vuam yog qhov yuav tsum tau, nws yog qhov tseem ceeb rau kev thov preheating thiab post-annealing.
Yuav ua li cas yog corrosion tsis sib piv?
440C ua yeeb yam zoo dua hauv kev tiv thaiv corrosive ib puag ncig, tab sis ob qib feem ntau tsis tshua tiv taus ntau dua li Austenitic steels xws li 304 lossis 316.
Tus nqi
440C Stainless hlau yog kim dua 420 vim nws cov peev txheej roj carbon ntau dua thiab cov khoom zoo dua.
