304 Stainless hlau tsis txiav txim Qhov zoo thiab tsis zoo los ntawm Magnetism

Date:Jan 03, 2019

Muaj ntau ntau yam ntawm Cov Hlau Stainless, los ntawm cov kub raws li lub koom haum qauv tau muab faib ua ntau pawg:


1, austenitic lub cev: xws li 304, 321, 316, 310,

2, martensite lossis ferrite lub cev hom: xws li 430, 420, 410, lwm yam.


Austenite yog tsis muaj hlau nplaum los yog tsis muaj zog, martensite los yog ferrite yog sib nqus. Feem ntau siv los ua cov yeeb nkab ntawm cov yeeb nkab uas tsis yog lub pob zeb 304, feem ntau qhov sib nqus lossis tsis muaj zog hlau nplua nuj, tiam sis vim yog vim muaj tshuaj lom neeg los ntawm kev hloov tshuaj los yog kev ua haujlwm txawv hauv lub Xeev yuav tshwm sim tau sib nqus, tab sis qhov no tsis tuaj yeem xav tias yog fake lossis unqualified, what yog vim li cas?


Nws tau hais los saum no tias austenite yog non-magnetic los yog tsis muaj zog magnetic, thiab martensite los yog ferrite yog sib nqus, vim smelting tivthaiv segregation los yog kho tsis kub, yuav ua rau austenitic 304 stainless hlau hauv tsawg tus martensite los yog ferrite cov ntaub so ntswg. Nyob rau hauv no txoj kev, 304 stainless hlau yuav muaj ib tug magnetism tsis muaj zog.


Tsis tas li ntawd, 304 stainless hlau tom qab ua cov txheej txheem, cov qauv ntaub so tseem yuav hloov dua siab tshiab rau martensite, ntau dua qhov deformation ntawm kev ua haujlwm, qhov kev hloov tshiab martensite, ntau dua qhov magnetism ntawm cov hlau. Zoo li ib pawg ntawm cov hlau khawm, qhov ntau lawm ntawm φ76 raj, tsis muaj kev sib raug zoo ntawm kev sib nqus, kev tsim cov φ9.5 raj. Vim tias qhov loj ntawm kev sib nqus ntawm lub kaum kev deformation yog qhov cuab kev, qhov ntau daim duab plaub fab xwm yeem vim qhov deformation loj dua cov raj raj, tshwj xeeb tshaj yog cov ntu folding, deformation khaus magnetism ntau dua. Yuav kom tshem tawm cov khoom sib nqus ntawm 304 steel los ntawm cov lus saum toj no, cov ntaub so ntsev austenitic ruaj ntseg tuaj yeem rov qab los ntawm kev kho kom zoo dua kub, yog li tshem tawm hlau nplaum.


Tshwj xeeb yog vim li cas saum toj no tshwm sim los ntawm 304 tsis muaj hlau tsis muaj hlau magnetism, thiab lwm yam ntaub ntawv ntawm stainless hlau, xws li 430, carbon steel magnetism tsis yog tib theem txhua, uas yog, 304 hlau magnetism ib txwm qhia tau hais tias tsis muaj zog magnetism. Qhov no qhia rau peb tias yog cov hlau tsis muaj zog tsis muaj zog los yog tsis yog hlau nplaum, nws yuav tsum raug txiav txim siab ua 304 lossis 316 khoom, thiab yog tias nws zoo ib yam li cov hlau nplaum carbon, nws qhia tau hais tias muaj zog magnetism vim nws tsis yog 304 khoom .
