Kev soj ntsuam ntawm Kev Ua Tau Zoo Ntawm Cov Hlau Stainless Bolts

Stainless hlau bolts xa mus rau ib lub ntsiab lus dav dav. Nyob rau hauv tsab xov xwm no, stainless hlau bolts suav nrog feem ntau stainless hlau fastener khoom xws li sab hauv hexagon, sab nrauv hexagon, ob lub taub hau, thiab txiv ntseej. Vim tias tom qab kev tsim cov hlau tsis muaj steel hlau ua tiav, tsis zoo li cov pa roj carbon steel bolts, uas xav tau tom qab kev kho cua sov los hloov nws cov khoom siv, tom qab kev tsim cov hlau stainless fasteners tiav, nws tuaj yeem siv ntev npaum li qhov chaw huv si, yog li. nws Cov yam ntxwv ua tau zoo yog qhov ua tau zoo ntawm cov khoom siv.

Piv nrog cov pa roj carbon zoo tib yam bolts, stainless hlau bolts muaj qhov zoo dua qhov kub thiab txias. Txawm li cas los xij, qhov saum npoo HRC Rockwell hardness ntawm stainless hlau bolts yog qis dua li carbon steel bolts. Lub ntsiab kev ua tau zoo ntawm stainless hlau bolts yog ntawm chav kawm tsis xeb, thiab nws tsis tuaj yeem oxidized nyob rau hauv qhov chaw huab cua raug rau xyoo lawm. Thiab ntawm qhov kub thiab txias heev, nws tuaj yeem ua haujlwm ib txwm tsis muaj kev hloov pauv ntawm lub zog lossis kev siv lub zog. Yog hais tias stainless hlau bolts tom qab ntau lawm yog passivated dua, lawv cov kub tsis kam thiab corrosion kuj yuav zoo dua. zoo tag nrho.

Stainless hlau bolts kuj muaj lub cev khoom hu ua electronegative ratio. Tau kawg,carbon steel boltskuj muaj qhov sib piv electronegative, tab sis qhov sib piv electronegative ntawm stainless hlau bolts ntawm tib lub specification yog ntau tshaj tsib npaug ntau dua li ntawm carbon steel bolts. Tus nqi cathode yog cuam tshuam nrog kev nthuav dav coefficient ntawm lub bolt. Nyob rau hauv ib txwm muaj, qhov siab dua qhov kub ntawm qhov chaw sab nraud, qhov kev nthuav dav ntawm ib feem yuav nce ntxiv. Rau cov khoom uas tsis tshua muaj cathode tus nqi, lub expansion system yuav nce mus rau ib tug tej yam nqi raws li kub nce. Tom qab ntawd, cov bolts tsis tuaj yeem siv, thiab cov bolts stainless hlau, uas muaj tus nqi cathode tsib npaug ntawm cov pa roj carbon zoo tib yam, tuaj yeem ua kom qhov sib txawv ntawm qhov sib txawv ntawm qhov kub thiab txias, uas yog vim li cas nws tiv taus qhov kub thiab txias.

Cov khoom siv ntawm stainless hlau bolts yog qhov nruab nrab. Nws tsis tuaj yeem muab piv nrog qee qhov muaj zog bolts saum qib 10.9, tab sis nws tsis yog phem dua li bolts hauv qab qib 8.8. Tsuav nws tsis yog lub sijhawm tshwj xeeb, qhov tseem ceeb stainless hlau bolts tuaj yeem siv tau. Ua tau raws li qhov yuav tsum tau siv. Tau kawg, kuj tseem muaj cov ntaub ntawv stainless hlau uas muaj zog heev, xws li duplex stainless hlau, thiab lwm yam, tab sis cov ntaub ntawv no yog siv los tsim cov khoom siv ntsia liaj qhov rooj, tus nqi siab dhau lawm, thiab kev siv tau zoo heev txo. Nrog rau txoj kev loj hlob ntawm technology, peb ntseeg hais tias lub zog ntawm conventionally siv stainless hlau bolts Nws kuj yuav maj mam txhim kho.

Nws yog feem ntau ntsib cov neeg muas zaub nug dab tsi yog lub zog qib ntawm stainless hlau bolts. Hais lus nruj me ntsis, stainless hlau bolts tsis muab faib ua qib. Yog tias koj yuav tsum hais tias nws muaj pes tsawg qib, ces 304 stainless hlau bolts yog sib npaug rau qib 6.8, thaum 316 stainless hlau bolts yog sib npaug rau qib 6.8. 8.8 qib, ntawm chav kawm, qhov no tsuas yog kev sib piv yooj yim, nws cov cuab yeej siv tshuab yog qhov nruj, thiab cov cuab yeej tshaj lij yog xav tau rau kev sim.

Vim li cas bolts ntawm cov khoom sib txawv muaj ntau yam sib txawv ntawm cov khoom siv sib txawv? Qhov no feem ntau yog vim cov ntsiab lus ntawm cov ntsiab lus alloy hauv cov ntaub ntawv sib txawv. Tom qab qhov sib xyaw ntawm ntau yam hlau, cov khoom sib txawv yuav raug tsim. Piv txwv li, cov ntsiab lus carbon nyob rau hauv cov khoom yog ib qho yooj yim hlau ntsiab nyob rau hauv txhua yam khoom. Tus nqi ntawm cov ntsiab lus carbon muaj qhov cuam tshuam zoo rau cov khoom siv. Feem ntau, thaum cov ntsiab lus ntawm cov pa roj carbon ntau, cov ntsia hlau lub zog yuav siab. Thaum cov ntsiab lus carbon tsawg, nws lub zog yuav qis, yog li lub zog ntawm stainless hlau bolts tsis siab npaum li lub zog siab bolts, feem ntau yog vim tsis muaj cov ntsiab lus carbon. Cov khoom sib txawv ntawm cov khoom yog ib hom kev tshawb fawb yooj yim, tsis yog hais tias koj tuaj yeem ntxiv ntau npaum li koj xav tau, tab sis muaj txiaj ntsig zoo. Yog vim li cas vim li cas stainless hlau bolts muaj cov antirust kev ua tau zoo uas carbon steel bolts tsis muaj yog ntawm chav kawm kuj muaj feem xyuam rau cov ntsiab lus carbon tsawg dua. Yog tias cov ntsiab lus carbon ntau ntxiv, lwm yam kev hloov pauv yuav tshwm sim hauv kev ua haujlwm.

Cov silicon uas muaj nyob rau hauv cov khoom yuav ntxiv dag zog rau lub ferrite, ua rau kom lub hardness ntawm lub ntsia liaj qhov rooj, thiab ua rau cov khoom ntau yas thiab yooj yim los tsim. Manganese nyob rau hauv cov ntaub ntawv muaj peev xwm neutralize leej faj nyob rau hauv cov khoom, yog li txo qhov kev cuam tshuam ntawm leej faj rau kev ua tau zoo ntawm lub bolts. Thiab leej faj yog insoluble hauv hlau, uas yuav txo tau lub zog thiab toughness ntawm bolts. Yog li ntawd, txhua lub hauv paus yuav ua nws lub luag haujlwm. Nrog rau txoj kev loj hlob ntawm cov khoom siv thev naus laus zis niaj hnub no, tsis muaj ib yam dab tsi ntxiv lossis txo qee yam khoom los hloov cov yam ntxwv ntawm cov khoom siv. Nws yuav tsum dhau los ntawm txhua yam khoom. Qhov cuam tshuam thiab kev hloov pauv tau tsim, thiab thaum kawg tuaj rau qhov tshwm sim.
