Hauv kev tsim khoom lag luam, qhov zoo ntawm cov ntaub ntawv raw yog qhov tseem ceeb rau kev ua tiav ntawm cov khoom kawg. Tswjhwm zoo ntawm cov ntaub ntawv raw suav nrog cov kev tshuaj ntsuam thiab cov ntawv xeem tsim los xyuas kom meej tias cov ntaub ntawv ua tau raws li cov lus qhia tshwj xeeb thiab cov qauv. Kab lus no yuav siv sijhawm sib sib zog nqus rau hauv cov txheej txheem tshuaj xyuas, suav nrog QU195 steel thiab ua kom muaj kev sim siab tshaj plaws thiab 316. Kev ua tau zoo ntawm cov ntaub ntawv no.

## To Taub Cov Ntaub Ntawv Raw

Cov khoom siv raw yog cov khoom siv yooj yim siv hauv kev tsim khoom. Cov Khoom Siv Raw ntau ntawm cov hlau thiab yas kom sib xyaw thiab ceramics. Ntawm lawv, hlau yog ib qho ntawm cov khoom siv dav tshaj plaws vim nws lub zog, kav ntev thiab versatility. Cov qhab nia sib txawv ntawm cov hlau, xws li Q195 thiab ntau yam stainless hlau qib, muaj cov khoom tshwj xeeb uas ua rau lawv haum rau cov ntawv thov sib txawv.

Q195 Hlau

Q195 yog cov roj carbon steel tsawg uas feem ntau siv nyob rau hauv kev tsim cov xov hlau, kav dej, thiab lwm yam txheej txheem txheej txheem. Nws tau paub txog nws qhov zoo weldability thiab formability, ua rau nws xaiv tau nrov hauv kev tsim kho thiab kev tsim khoom lag luam. Txawm li cas los xij, kom ntseeg tau tias Q195 hlau ua tau raws li cov qauv tsim nyog, nws yuav tsum tau yov kev tswj hwm kev tswj hwm zoo.

### Stainless Hlau Qib Pib: 201, 304 thiab 316

Stainless hlau yog lwm cov khoom siv tseem ceeb hauv kev tsim khoom lag luam, tshwj xeeb tshaj yog cov khoom lag luam corrosion, xws li cov khoom noj ua haus, thiab cov ntaub ntawv thov ua khoom noj. Cov qhab nia pheej yig tshaj plaws ntawm cov hlau tsis muaj xws li 201, 304, thiab 316, txhua tus nrog cov khoom ntiag tug:

- ** 201 stainless hlau **: Cov qib no yog paub txog nws cov zoo oxidation tiv taus thiab feem ntau siv hauv kev siv corrosion tsis kam. Nws tsis tshua kim tshaj lwm tus hlau tsis muaj lub taub hau, tab sis yuav tsis ua tau zoo li hauv kev txhim kho ib puag ncig.

- ** ** 304 Stainless Hlau **: Qhov no yog ib qho ntawm feem ntau cov qib siv ntawm cov hlau stainless vim nws zoo heev corrosion tsis kam thiab cov kws kho zoo. Nws yog feem ntau siv rau hauv chav ua noj ua noj, kev ua zaub mov noj, thiab ntim tshuaj.

- ** ** 316 stainless hlau ": paub txog nws cov kev zam corrosion, tshwj xeeb yog siv rau hauv cov hlau marine thiab ib puag ncig uas muaj qee yam tsis muaj tshuaj hnyav.

## Tseem ceeb ntawm kev tswj kom zoo

Tswjhwm zoo ntawm cov ntaub ntawv raw yog qhov tseem ceeb kom ntseeg tau tias cov ntaub ntawv siv hauv kev tsim cov ntaub ntawv tshwj xeeb. Tus txheej txheem no cuam tshuam ntau cov tshev tseem ceeb thiab kev sim, suav nrog:

### 1. Khij cov bandwidth thiab tuab

Qhov dav thiab tuab ntawm cov khoom siv raw yog qhov tseem ceeb uas cuam tshuam rau kev ua tau zoo ntawm cov khoom kawg. Piv txwv li, nrog cov phiaj hlau lossis cov ntawv txheeb, cov tuab tuab yuav tsum muaj kev ua kom ntseeg tau tias muaj zog sib zog thiab kav ntev. Ib qho kev sib txawv twg tuaj yeem ua rau cov ntsiab lus tsis muaj zog hauv cov qauv, uas yuav ua rau tsis ua haujlwm thaum siv.

Thaum lub sij hawm kuaj xyuas, cov tuam ntxhab siv calipers thiab micrometers kom ntsuas qhov tseeb ntawm cov khoom siv. Txoj siv tawv dav kuj tseem ntsuas kom ntseeg tau tias nws ua tau raws li cov kev taw qhia tshwj xeeb. Tej yam uas tsis sib xws yuav tsum tau daws ua ntej cov khoom tau pom zoo siv.

### 2. Hardness Test

Hardness yog kev ntsuas ntawm cov khoom siv tiv thaiv kom deformation thiab hnav. Hardness yog cov khoom siv tseem ceeb rau cov ntawv thov uas xav tau lub zog durability thiab muaj zog. Ntau txoj kev sim hardness, xws li rockwell, brinell, thiab vickers, tuaj yeem siv los txiav txim siab ntawm cov khoom siv tawv.

Piv txwv li, Q195 hlau yuav yog qhov kev ntsuas nyuaj kom ntseeg tau tias nws ua tau raws li qhov xav tau rau nws siv. Ib yam li ntawd, 201, 304 thiab 316 Stainless hlau qib tseem yuav tsum tau sim ua lawv txoj kev ua tau zoo, uas cuam tshuam rau lawv cov kev ua tau zoo.

### 3. Tensile xeem

Tensile kev soj ntsuam yog lwm qhov tseem ceeb ntawm cov khoom siv raw ua kom zoo. Qhov kev ntsuas no ntsuas lub zog thiab duction ntawm cov khoom siv los ntawm kev thov lub zog tensile kom txog thaum cov khoom tawg. Cov txiaj ntsig muab cov ntaub ntawv muaj txiaj ntsig txog cov khoom siv tau tawm los lub zog, lub zog kawg tensile lub zog, thiab elongation.

Piv txwv, Tensile kuaj ntawm Q195 cov hlau pab txiav txim nws cov ntawv thov cov txheej txheem, thaum sim nws lub peev xwm tiv thaiv kev ntxhov siab hauv ntau qhov chaw ib puag ncig. Cov ntaub ntawv tau los ntawm Tensile kev soj ntsuam yog qhov tseem ceeb rau kom ntseeg tau tias cov khoom yuav ua raws li tau txais raws li qhov kev xav tau hauv daim ntawv thov.

## Hauv kev xaus

Tswjhwm zoo ntawm cov khoom siv raw yog ib qho tseem ceeb los xyuas kom meej meej txog kev ncaj ncees thiab kev ua tau zoo ntawm cov khoom kawg. Los ntawm kev soj ntsuam kom huv si thiab cov ntaub ntawv xeem xws li Q195 steel thiab 201, 304 thiab 316 Cov teeb meem uas muaj peev xwm ntes tau txhua yam teeb meem tseem ceeb ua ntej lawv ua teeb meem loj. Txheeb xyuas bandwidth, tuab, hardness, hardness thiab ua Tensile kev ntsuam xyuas yog txhua yam tseem ceeb ntawm cov txheej txheem no. Thaum kawg, muaj zog tswj hwm lub cev tsis tsuas yog txhim kho cov khoom muaj kev cia siab, tab sis kuj txhawb nqa tag nrho kev ua tiav ntawm kev tsim khoom lag luam. Raws li kev lag luam txuas ntxiv hloov zuj zus, qhov tseem ceeb ntawm raw khoom siv zoo yuav tsum muaj pob kws ua tau zoo.
