Dab tsi yog qhov sib txawv ntawm 51crrv4 thiab 50crv4?

Qhov sib txawv ntawm51crrv4 thiab 50crvr4Part feem ntau nyob rau hauv lawv cov tshuaj muaj pes tsawg leeg, cov khoom siv mechanies, thiab cov ntawv thov. Ob qho tib si yog chromium - vanadium alloy alloy siv rau high- Lub zog Cheebtsam zoo li Springs, Shafts, thiab lub zog.

Ntawm no yog qhov tawg:

Cov pa roj carbon (c):

50crvrv4: ~ 0.50% carbon (nominal).

51Crrvrrv4: ~ 0.51% carbon (me ntsis siab dua).

Thaum cov pa roj carbon sib txawv yog tsawg heev, nws cuam tshuam hardness thiab lub zog.

Chromium (cr) thiab vanadium (v):

Ob qho tib si cov hlau muaj cov chromium zoo sib xws (~ 0.9-1.2%) thiab Vanadium (~ 0.15-0.25%) cov ntsiab lus. Qhov tseem ceeb tshaj yog cov ntsiab lus carbon, uas yog me ntsis ulit lawv cov khoom.

Hardness thiab lub zog:

• 51Crrvrrv4: Ib nyuag qib zog tensile lub zog thiab hardness vim nws marginally nce cov ntsiab lus carbon.
• 50crvrv4: kev du me ntsis thiab tawv tawv, ua rau nws yooj yim dua los tsim lossis tshuab.

HardenTability:

Ob qho tib si ntawm ob leeg teb zoo rau kev kho cua sov (quenching thiab tempering), tab sis 51crrvrv4 yuav ua tiav ntau dua qhov nyuaj tom qab ua kom tawv.

50crrv4:

Siv dav siv rau Springs (kauj, nplooj ntoos, thiab cov khoom siv uas yuav tsum tau sib npaug ntawm lub zog thiab kev qaug zog tsis kam. Nquag nyob rau hauv kev ncua cov khoom lag luam thiab qhov chaw tsav degretrain.

51crrrrrv4:

Siv nyob rau hauv cov ntawv thov sib xws tab sis qhov twg me ntsis siab dua lossis hnav tsis kam yog xav tau. Feem ntau xaiv rau high - muaj kev ntxhov siab ib yam li kev hnyav- duty} duty} Deartning.

Ob qib kawm tau ua raws li EN 10083-3 (European qauv).

50crvrv4 yog cov feem ntau yog hais txog, thaum 51ccrvrv4 yog qhov tsis tshua muaj zog tsawg dua.

Sib npaug rau Asmeskas cov qib: 50crv4 ≈ t t t t t ≈ ≈ ≈ ≈ ≈ ≈ rau 6150 hlau).

51crrv4 tsis tau ncaj qha rau peb sib npaug tab sis yog ze rau ASTM A689 (hloov 6150).

Qhov sib txawv yog hloov maj mam:

• 51crrvrrv4 muaj me ntsis siab dua lub zog / hardnessness.
• 50crvr4 balanced muaj zog nrog ductility zoo.

Qhov kev xaiv yog nyob ntawm cov kev cai muab rau daim ntawv thov (piv txwv li, thauj khoom muaj peev xwm vs.. Yuav tsum tau sab laj cov ntaub ntawv datasheets rau kev kho kom zoo nkauj thiab cov txheej txheem kev ua tau zoo.

Cov khoom siv twg yog sib npaug rau 51crvv4?

DIN 1.8159 Hlau, tau lees paub los ntawm ntau yam qauv thiab cov npe xws li 51crrvrv4, AISI 6150, thiab ntau dua, sawv hauv lub ntiaj teb cov ntaub ntawv vim nws cov khoom sib xyaw ua ke.

Yog 51crrv4 hlau zoo?

51crrrrrrrrrrrrv4 steel yog qhov nruab nrab- cov roj carbon alloy hlau feem cais ua hlau caij nplooj ntoos hlav. Nws yog tus cwj pwm los ntawm nwsLub zog siab, kev nruj heev tiag tiag, thiab kev hnav tsis muaj kev tiv thaiv zoo, ua rau nws haum tshwj xeeb rau cov ntawv thov yuav tsum ua kom qaug zog ua kom muaj zog thiab lub zog.

Dab tsi yog qhov sib txawv ntawm 50crrv4 thiab 51crvv4?

Qhov tseem ceeb tshaj yog cov ntsiab lus carbon, uas yog me ntsis ulit lawv cov khoom. Hardness thiab lub zog:51Crrvrrv4: Ib nyuag qib zog tensile lub zog thiab hardness vim nws marginally nce cov ntsiab lus carbon. 50crvrv4: kev du me ntsis thiab tawv tawv, ua rau nws yooj yim dua los tsim lossis tshuab.

Khoom siv yog li cas 50crv4 sib npaug khoom?

Cov kev cuam tshuam 1.8159 specifications thiab sib npaug steel qib

Muaj dab tsi 50 cov ntaub ntawv CRV?

Cov khoom siv 50 CRV 4 belongs rau cov pab pawg "Quenched thiab tempered steels"
