Kev Ua Kom Ruaj Khov Thaum Nag Los (PH) Cov Hlau Stainless (Sib Nqus)

  • Cov Qib Kawm: 17-4PH, 15-5PH
  • Nta: Muaj zog thiab tawv tom qab kev laus kho
  • Kev coj cwj pwm sib nqus: Sib nqus tom qab kev kho cua sov

2. Vim li cas qee cov hlau tsis xeb thiaj li muaj hlau nplaum?

Cov khoom siv sib nqus ntawm cov hlau tsis xeb nyob ntawm nws cov qauv siv lead ua. Cov hlau Austenitic (xws li 304 thiab 316) muaj cov qauv uas tsis txhawb nqa magnetism, thaum cov hlau ferritic thiab martensitic muaj cov qauv uas sib phim nrog cov teb sib nqus.

Txawm tias cov hlau tsis muaj hlau nplaum kuj tuaj yeem tsim ib feem ntawm magnetism vim yog kev hloov pauv xws li khoov, dov, lossis machining (ua haujlwm txias).

3. Cov Khoom Sib Nqus los ntawm Qib

Qib Hom Sib nqus Cov Lus Cim
304 Austenitic Tsis yog (Me ntsis tom qab ua haujlwm txias) Feem ntau cov qib stainless hlau
316 Austenitic No Cov ntawv thov hauv dej hiav txwv, tiv taus cov chlorides
430 Ferritic Yog Siv rau hauv cov khoom siv hauv chav ua noj thiab cov khoom dai kom zoo nkauj
410 Martensitic Yog Cov ntaub ntawv hniav, cov ncej twj tso kua mis
17-4PH Kev Ua Kom Nag Los Yog Muaj zog tom qab laus; siv rau hauv aerospace
2205 Ob chav Ib nrab Zoo heev tsis kam rau corrosion cracking

4. Qhov twg Cov Khoom Siv Sib Nqus Tseem Ceeb

Kev nkag siab seb cov hlau tsis xeb puas yog hlau nplaum yog qhov tseem ceeb hauv qee yam lag luam:

Cov Ntawv Thov Uas Yuav Tsum Tau Cov Hlau Stainless Uas Tsis Yog Hlau Sib Nqus

  • Cov cuab yeej kho mob (MRI sib xws)
  • Cov thawv hluav taws xob thiab kev tiv thaiv
  • Kev tsim khoom noj thiab tshuaj

Cov ntawv thov uas xav tau hlau nplaum sib nqus

  • Cov cav thiab cov generators
  • Cov sib cais sib nqus
  • Cov khoom siv hluav taws xob xws li qhov rooj qhov cub

5. Yuav Ua Li Cas Kuaj Xyuas Qhov Sib Nqus

Muaj cov txoj hauv kev yooj yim los txiav txim siab seb cov hlau tsis xeb puas yog hlau nplaum:

  • Kev Ntsuas Hlau nplaum:Siv ib lub hlau nplaum txheem los saib seb nws puas lo.
  • Sensor nyhuv Hall:Ntsuas lub zog ntawm lub zog sib nqus.
  • Cov Khoom Siv Tshuaj Xyuas:Txiav txim siab qhov sib xyaw thiab cov qauv ntawm cov hlau.

6. Kev Ua Haujlwm Txias Puas Ua Rau Muaj Hlau Nplaum?

Yog. Kev ua haujlwm txias tuaj yeem ua rau cov qauv siv lead ua ntawm cov hlau tsis xeb austenitic tsis zoo thiab ua rau muaj kev teb sib nqus ib nrab. Kev ua kom sov (ua kom sov ces txias qeeb qeeb) yuav txo qhov sib nqus no tab sis yuav cuam tshuam rau lub zog lossis kev tiv thaiv xeb.

PH Hlau 17-4PH Yog Siv rau hauv aerospace thiab cov khoom siv thauj khoom siab

9. Xaus Lus

Tsis yog txhua qib stainless hlau yog sib nqus. Qib Austenitic xws li 304 thiab 316 feem ntau tsis yog sib nqus thiab haum rau cov ntawv thov uas xav tau kev cuam tshuam sib nqus tsawg kawg nkaus. Qib Ferritic thiab martensitic yog sib nqus thiab muaj txiaj ntsig zoo rau kev siv tshuab thiab kev tsim kho. Duplex thiab PH steels muab kev sib npaug ntawm cov khoom thiab qhov nruab nrab magnetism.

Kev nkag siab txog qhov sib txawv no tso cai rau koj xaiv cov khoom siv zoo rau koj daim ntawv thov - txawm tias nws xav tau cov khoom sib nqus lossis yuav tsum zam lawv.
