Vim li cas 304 Stainless Hlau Yeeb Nkab Yog Sib Nqus Thaum Siv

Hauv lub neej, peb feem ntau siv cov hlau nplaum ntawm cov raj los txiav txim seb cov hlau tsis zoo los yog phem, tab sis qhov tseeb, txoj kev no yog qhov tsis txaus ntseeg. Piv txwv li, peb cov zinc tube alloys thiab tooj liab tube alloys tuaj yeem ua raws li cov tsos thiab xim ntawm cov hlau tsis muaj hlau, thiab lawv kuj tsis sib nqus, uas yooj yim rau kev ua yuam kev rau stainless hlau. Txawm hais tias 304 steel uas peb tam sim no siv feem ntau, tom qab ua haujlwm txias, kuj tseem yuav muaj ntau theem ntawm cov yeeb nkab hlau nplaum, yog li peb tsis tuaj yeem txiav txim siab seb cov hlau tsis zoo los yog phem los ntawm seb puas muaj cov yeeb nkab sib nqus. tiam 304 Stainless hlau yeeb nkab yog magnetic.

Feem ntau, kev lag luam stainless hlau welded yeeb nkab tuaj yeem muab faib ua ob hom raws li nws cov qauv ntawm chav tsev kub. Ib qho yog austenitic stainless hlau yeeb nkab, xws li 304321 yeeb nkab, 316 yeeb nkab, 310 yeeb nkab, thiab lwm yam, thiab lwm yam yog cov yeeb nkab martensite los yog ferritic stainless hlau yeeb nkab, xws li 430420 yeeb nkab, 410 yeeb nkab, thiab lwm yam., hos austenitic stainless hlau yeeb nkab yog cov hlau tsis muaj hlau nplaum los yog cov hlau tsis muaj zog, cov yeeb nkab steel yog 0. tubeless magnetic los yog nrog yog magnetic.

Peb feem ntau hais tias 304 stainless hlau yog non-magnetic tubular stainless hlau, uas txhais tau hais tias nws cov magnetic index yog qis dua ib qho nqi. Uas yog hais, stainless hlau feem ntau muaj ib tug tej yam degree ntawm raj hlau nplaum. Lub austenitic stainless hlau uas tau tsa ua ntej yog cov hlau nplaum tsis muaj zog lossis tsis muaj zog sib nqus, thaum ferritic thiab martensitic stainless hlau muaj cov khoom sib nqus tubular, uas yog vim muaj cov khoom sib cais lossis cov kav dej tsis zoo thaum smelting, Qhov no ua rau me me ntawm martensite lossis ferrite qauv nyob rau hauv austenitic 304 stainless hlau yuav tsis muaj zog 0. Stainless Hlau Tube. Tsis tas li ntawd, tom qab ua haujlwm txias, cov qauv ntawm 304 stainless hlau raj yuav hloov mus rau hauv martensite. Nrog rau ntau dua deformation ntawm txias tube ua, lub martensite hloov dua siab tshiab raj, lub zog hlau nplaum yuav muaj zog.

Yog li ntawd, cov khoom sib nqus ntawm cov ntaub ntawv yog txiav txim siab los ntawm qhov tsis tu ncua ntawm cov qauv molecular ntawm cov raj thiab isotropy ntawm cov khoom siv hluav taws xob, uas tuaj yeem suav tias yog cov khoom siv lub cev ntawm cov ntaub ntawv, thaum lub corrosion kuj ntawm cov ntaub ntawv yog txiav txim los ntawm cov tshuaj muaj pes tsawg leeg ntawm cov ntaub ntawv, uas yog cov tshuaj muaj pes tsawg leeg ntawm cov ntaub ntawv thiab cov hlab, thiab tsis muaj dab tsi ua nrog seb cov ntaub ntawv yog sib nqus los yog tsis.
