304 Cov Hlau Tseem Muaj Cov Hlau Hlau. Txawm nws yog hlau nplaum lossis Tsis tuaj yeem tsis txiav txim qhov zoo ntawm Cov Hlau Stainless. Koj Puas Paub?

Txawm hais tias 304 hlau yog hlau nplaum lossis tsis tuaj yeem txiav txim siab qhov tsis zoo ntawm cov hlau tsis huv

Tib neeg feem ntau xav tias cov hlau nplaum nqus cov khoom siv hlau tsis huv los txheeb xyuas lawv qhov zoo thiab qhov tseeb. Lawv tsis ntxim nyiam thiab tsis yog hlau nplaum. Lawv suav tias yog qhov zoo thiab muaj tiag; yog tias lawv yog cov hlau nplaum, lawv suav tias yog cov khoom cuav. Qhov tseeb, qhov no yog ib txoj hauv kev ib leeg nkaus xwb thiab siv tsis tau los txheeb xyuas qhov ua yuam kev.

Muaj ntau hom hlau tsis huv, uas tuaj yeem faib ua ob peb pawg raws li kev teeb tsa lub koom haum ntawm chav sov:

1. Hom Austenitic: xws li 304, 321, 316, 310, thiab lwm yam;

2. Martensite lossis hom ferrite: xws li 430, 420, 410, thiab lwm yam.

Austenite tsis yog hlau nplaum lossis tsis muaj zog sib nqus, thiab martensite lossis ferrite yog sib nqus.

Cov hlau tsis huv feem ntau siv los ua cov ntawv raj zoo nkauj feem ntau yog cov khoom siv austenitic 304. Feem ntau hais lus, nws tsis yog hlau nplaum lossis tsis muaj zog sib nqus. Txawm li cas los xij, vim muaj kev hloov pauv ntawm cov tshuaj lom neeg lossis cov txheej txheem sib txawv los ntawm kev zom, cov hlau nplaum kuj tseem tuaj yeem tshwm sim, tab sis qhov no tsis tuaj yeem suav tias yog vim li cas thiaj li cuav lossis tsis tsim nyog?

Raws li tau hais los saum no, austenite tsis muaj hlau nplaum lossis tsis muaj zog sib nqus, thaum martensite lossis ferrite yog sib nqus. Vim yog kev sib cais sib cais lossis kev kho cua sov tsis raug thaum lub sij hawm zom, ib qho me me ntawm martensite lossis ferrite hauv austenitic 304 stainless hlau yuav tshwm sim. Lub cev nqaij daim tawv. Ua li no, 304 cov hlau tsis muaj zog yuav muaj cov khoom sib nqus tsis muaj zog.

Ib qho ntxiv, tom qab 304 xim hlau tsis txias ua haujlwm, cov qauv kuj tseem yuav hloov pauv mus rau hauv martensite. Qhov ntau dua qhov txias ua haujlwm deformation, ntau dua kev hloov pauv martensite thiab ntau dua cov khoom sib nqus ntawm cov hlau. Zoo li ib pawg ntawm cov hlua hlau, Φ76 cov kav dej tau tsim tawm yam tsis muaj qhov sib nqus induction, thiab pipes9.5 cov kav dej tau tsim. Vim tias kev khoov deformation loj dua, qhov sib nqus induction pom tseeb dua. Kev hloov pauv ntawm lub raj plaub fab plaub fab loj dua li ntawm cov raj puag ncig, tshwj xeeb tshaj yog cov ces kaum ib feem, qhov kev hloov pauv yog khaus ntau dua thiab cov hlau nplaum tau pom tseeb dua.

Txhawm rau tshem tawm cov khoom sib nqus ntawm 304 hlau ua los ntawm cov laj thawj hais los saum toj no, cov qauv austenite tuaj yeem rov qab thiab ruaj khov los ntawm kev kho kub kub, yog li tshem tawm cov khoom sib nqus.

Tshwj xeeb, cov hlau nplaum ntawm 304 stainless hlau ua los ntawm cov laj thawj saum toj no tsis nyob rau qib ib yam li cov hlau nplaum ntawm lwm cov ntaub ntawv, xws li 430 thiab carbon hlau. Ntawd yog hais, cov hlau nplaum ntawm 304 hlau ib txwm qhia tias tsis muaj zog hlau nplaum.

Qhov no qhia peb tias yog cov hlau tsis muaj zog tsis muaj zog lossis tsis sib nqus txhua, nws yuav tsum raug txiav txim raws li 304 lossis 316 cov khoom siv; yog tias nws zoo ib yam li cov pa roj carbon, nws qhia tau tias muaj cov hlau nplaum muaj zog, vim nws tau txiav txim tias tsis yog 304 cov khoom siv.
