Stainless hlau cua sov kav yog feem ntau siv

Rau kev lag luam cua sov kav, stainless hlau cua sov kav yog feem ntau siv. Stainless hlau kuj yog cov khoom siv dav tshaj plaws. Yog vim li cas vim li cas stainless hlau yog dav siv tsis yog vim nws tsis xeb, tab sis kuj nyob ntawm qhov ntxim nyiam ntawm nws cov khoom. Cov qib sib txawv ntawm cov ntaub ntawv stainless hlau muaj qhov sib txawv corrosion kuj. Tom ntej no, Yancheng Hongchuang yuav tham txog ob lub ntsiab ntawm stainless hlau:

Qhov tseem ceeb tshaj plaws hauv cov ntaub ntawv stainless hlau yog kev sib xyaw ntawm chromium thiab npib tsib xee los ua chromium nickel stainless hlau. Ntxiv ntau cov nickel rau hom stainless hlau no yog kom tau txais ib qho austenitic qauv, yog li txhim kho nws cov corrosion kuj thiab processability. Nws muaj zog plasticity thiab toughness nyob rau hauv chav tsev kub thiab tsis kub, yog tsis sib nqus, thiab muaj zoo kuj rau intergranular corrosion.

(1) Chromium plays lub luag haujlwm tseem ceeb hauv corrosion kuj ntawm stainless hlau

Chromium yog lub hauv paus ntsiab lus txiav txim siab corrosion kuj ntawm stainless hlau, vim hais tias muaj chromium nyob rau hauv cov hlau yuav ua rau passivation nyob rau hauv lub oxidizing nruab nrab, tsim ib tug nyias zaj duab xis nyob rau hauv uas chromium yog enriched. Qhov siab dua cov ntsiab lus chromium hauv steel, qhov muaj zog ntawm nws cov corrosion kuj. Tsis tas li ntawd, chromium tuaj yeem txhim kho cov khoom siv kho tshuab thiab thev naus laus zis ntawm cov hlau.

(2) Cov nyhuv ntawm Nickel ntawm Stainless Hlau

Tsuas yog thaum nws ua ke nrog chromium nws tuaj yeem ua kom pom tseeb. Nickel yog ib qho khoom siv hlau uas tsim cov austenite. Thaum nickel siv ua ke nrog chromium, nws tuaj yeem hloov cov qauv metallographic los ntawm ib theem ferrite mus rau ob theem qauv ntawm austenite thiab ferrite. Tom qab kev kho cua sov, lub zog tuaj yeem txhim kho, ua rau muaj zog xeb kuj thiab zoo deformability.

Niaj hnub no cov lus qhia luv luv kuj tau teb rau qee cov neeg siv khoom cov lus nug txog vim li cas qee zaum lawv hais tias nws yog ua los ntawm stainless hlau, tab sis tus nqi ntawm cov kav dej cua sov muaj ntau qhov yuam kev. Nws yog vim hais tias cov khoom hauv stainless hlau sib txawv, uas ua rau ntau qib sib txawv ntawm stainless hlau. Yog li ntawd, tus nqi ntawm cov khoom siv sib txawv, yog li yuav muaj qhov yuam kev tseem ceeb. Cov khoom siv feem ntau yog stainless hlau 201 (feem ntau hu ua stainless hlau), ua raws li stainless hlau 304, stainless hlau 321, stainless hlau 316, thiab 2520 cov ntaub ntawv. Ntau qhov nce ntxiv.
