Puas yog 409 stainless hlau sib nqus?

Stainless hlau yog cov khoom siv nrov siv hauv ntau qhov kev lag luam vim nws cov corrosion kuj thiab durability. Ntawm ntau hom stainless hlau, 409 yog ib qib tshwj xeeb uas feem ntau siv rau hauv cov ntawv thov uas raug rau qhov chaw corrosive. Txawm li cas los xij, ib qho lus nug uas tshwm sim thaum xav txog cov khoom siv no yog tias 409 stainless hlau puas yog hlau nplaum.

 

Cov tshuaj muaj pes tsawg leeg ntawm 409 stainless hlau

409 stainless hlau yog chromium-nickel alloy uas belongs rau tsev neeg ferritic stainless hlau. Nws muaj nyob nruab nrab ntawm 10.5% thiab 11.7% chromium, uas ua rau nws corrosion-resistant, thiab ib tug me me ntawm npib tsib xee, feem ntau nyob ib ncig ntawm 0.5%. Txawm li cas los xij, qhov sib txawv tseem ceeb ntawm 409 thiab lwm yam stainless hlau alloys yog nws cov ntsiab lus carbon, uas yog siab dua lwm cov qib stainless hlau.

 

Magnetic Properties ntawm 409 Stainless Hlau

Cov ntsiab lus carbon hauv 409 stainless hlau ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab nws cov khoom sib nqus. Txij li thaum nws muaj cov ntsiab lus carbon ntau dua, nws yooj yim dua los tsim martensite, ferromagnetic theem ntawm hlau-carbon alloys. Qhov kev tsim martensite no ua rau 409 stainless hlau tsis muaj zog hlau nplaum.

Tam sim no, lo lus "tsis muaj zog hlau nplaum" yog qhov tseem ceeb ntawm no. Thaum 409 stainless hlau tsis muaj zog sib nqus zoo ib yam li lwm cov hlau alloys, nws tseem muaj qee qhov kev sib nqus ntawm cov hlau nplaum. Qhov no yog vim muaj cov ntsiab lus ferromagnetic xws li hlau thiab carbon nyob rau hauv nws muaj pes tsawg leeg.

 

Kev siv tswv yim ntawm 409 stainless hlau

Cov khoom sib nqus ntawm 409 stainless hlau tuaj yeem cuam tshuam rau nws siv hauv qee qhov tshwj xeeb. Piv txwv li, hauv cov khoom siv hluav taws xob lossis cov khoom siv kho mob uas xav tau kom tsis txhob muaj kev cuam tshuam hauv kev sib nqus, siv 409 stainless hlau yuav tsis yog qhov kev xaiv zoo tshaj plaws. Hauv lwm qhov chaw, xws li kev tsim kho thiab kev tsim tsheb, nws cov yam ntxwv sib nqus yuav tsis muaj kev cuam tshuam ntau.

Hauv cov ntsiab lus, 409 stainless hlau tsis muaj zog hlau nplaum vim nws cov ntsiab lus carbon thiab tsim ntawm martensite. Txawm hais tias nws tsis muaj zog sib nqus zoo ib yam li lwm cov hlau alloys, nws tseem muaj qee qhov kev sib nqus ntawm cov hlau nplaum. Qhov no yuav tsum tau coj mus rau hauv tus account thaum xav txog nws txoj kev siv nyob rau hauv daim ntawv thov uas magnetism tej zaum yuav muaj kev txhawj xeeb.
