Nyob rau hauv cov qauv ntawm cov khoom yas, cov khoom siv ntawm cov ntsia hlau muaj feem xyuam rau cov yam ntxwv ntawm cov khoom, xws li qhov loj ntawm lub zog, thiab stainless hlau yog siv rau sab nraud ntawm cov yas, thiab carbon steel screws yog siv rau ntawm lub sab hauv.Yuav ua li cas xaiv stainless hlau?
1: Nyob rau hauv layman cov ntsiab lus, carbon steel screws tsis muaj hlau nrog alloy ntsiab ntxiv txhob txwm tshaj tawm, thiab stainless hlau screws yog hlau nrog siab alloy ntsiab lus ntxiv rau kev tiv thaiv xeb.
2: Stainless hlau screws yog kim tshaj li carbon steel screws.
3: Ob hom ntsia hlau no txawv, yog li lawv tsis tuaj yeem muab piv rau.Carbon steel screws feem ntau muaj zog dua stainless hlau screws, tab sis lawv yooj yim rau xeb.
Cov ntaub ntawv ntawm stainless hlau screws thiab carbon steel screws yog txawv, thiab ib puag ncig ntawm kev siv kuj txawv.Cov pa roj carbon steel tsis zoo corrosion kuj, thiab cov bolts yuav xeb kom tuag tom qab ntev.Stainless hlau screws kuj zoo dua.
Stainless hlau ntsia hlau
Cov ntaub ntawv ntawm stainless hlau screws thiab carbon steel screws txawv, thiab ib puag ncig uas lawv siv kuj txawv.
Kev tiv thaiv corrosion ntawm carbon hlau yog qhov tsis zoo, thiab cov bolts yuav xeb kom tuag tom qab ntev.Stainless hlau bolts kuj zoo dua.Nov yog qee cov ntaub ntawv rau stainless hlau bolts:
Kev faib cov khoom ntawm stainless hlau screws
Nws yog siv rau zus tau tej cov stainless hlau screws.Cov ntaub ntawv ntawm stainless hlau screws yog muab faib ua austenitic stainless hlau, ferritic stainless hlau, martensitic stainless hlau thiab nag lossis daus hardening stainless hlau.Kev xaiv ntawm stainless hlau screws kuj yog nyob rau hauv txoj cai.Los ntawm dab tsi nam, cia koj xaiv stainless hlau screws koj xav tau.
Tom qab kev txiav txim siab zoo thiab ua tiav ntawm tsib yam no, qib, ntau yam, kev qhia tshwj xeeb thiab cov khoom siv ntawm stainless hlau screws thaum kawg txiav txim siab.
Ferritic stainless hlau
Hom 430 zoo tib yam chromium steel muaj kev tiv thaiv corrosion zoo dua thiab kub ua haujlwm dua li Hom 410, thiab yog hlau nplaum, tab sis nws tsis tuaj yeem muaj zog los ntawm kev kho cua sov.Nws yog tsim rau stainless hlau nrog ib tug me ntsis ntau dua corrosion kuj thiab tshav kub tsis kam thiab dav siv zog yuav tsum tau.ntsia hlau.
Martensitic stainless hlau
Hom 410 thiab Hom 416 tuaj yeem ua kom muaj zog los ntawm kev kho cua sov, nrog lub hardness ntawm 35-45HRC thiab zoo machinability.Lawv yog cov cua kub-resistant thiab corrosion-resistant stainless hlau screws rau dav siv.Hom 416 muaj cov ntsiab lus sulfur me ntsis thiab yog ib qho yooj yim-rau-txiav stainless hlau.
Hom 420, cov ntsiab lus sulfur?R0.15%, txhim kho txhua yam khoom, tuaj yeem ua kom muaj zog los ntawm kev kho cua sov, qhov siab tshaj plaws hardness tus nqi 53 ~ 58HRC, siv rau stainless hlau screws yuav tsum muaj zog dua.
Stainless hlau ntsia hlau
Precipitation Hardened Stainless hlau
17-4PH, PH15-7Mo, lawv tuaj yeem tau txais lub zog siab dua li 18-8 stainless hlau li niaj zaus, yog li lawv siv rau lub zog siab, corrosion-resistant stainless hlau screws.
A-286, tsis yog-tus qauv stainless hlau, muaj kev tiv thaiv corrosion ntau dua li 18-8 hom stainless hlau, nrog rau cov khoom siv zoo ntawm qhov kub siab.Nws yog siv los ua lub zog siab, kub-tiv taus thiab corrosion-resistant stainless hlau screws, uas tuaj yeem siv txog 650-700 ° C.
Stainless hlau ntsia hlau
Austenitic stainless hlau
Cov qib siv feem ntau yog 302, 303, 304, thiab 305, uas yog plaub qib ntawm qhov hu ua "18-8" austenitic stainless hlau.Seb nws yog corrosion kuj, los yog nws mechanical zog zoo ib yam.Lub hauv paus ntsiab lus ntawm kev xaiv yog cov txheej txheem tsim khoom ntawm stainless hlau screws, thiab cov txheej txheem nyob ntawm qhov loj thiab cov duab ntawm stainless hlau screws, thiab tseem nyob ntawm qhov ntau ntawm cov khoom.
Hom 302 yog siv rau machined screws thiab self-tapping bolts.
Hom 303 Txhawm rau txhim kho qhov kev ua tau zoo, ib qho me me ntawm leej faj ntxiv rau Hom 303 stainless hlau, uas yog siv los ua cov txiv ntoo los ntawm cov khoom lag luam.
Hom 304 yog tsim rau kev ua cov hlau stainless screws los ntawm cov txheej txheem kub taub hau, xws li cov lus qhia ntev dua thiab cov kab loj loj, uas yuav dhau ntawm cov txheej txheem txias.
Hom 305 yog tsim rau kev ua stainless hlau screws los ntawm cov txheej txheem txias taub hau, xws li txias tsim ceev thiab hexagonal bolts.
Hom 309 thiab Hom 310 muaj cov ntsiab lus Cr thiab Ni ntau dua li Hom 18-8 stainless hlau, thiab haum rau stainless hlau screws ua haujlwm ntawm qhov kub thiab txias.
316 thiab 317 hom, lawv ob leeg muaj hlau alloying Mo, yog li lawv lub zog kub thiab corrosion kuj yog siab dua 18-8 stainless hlau.
Hom 321 thiab Hom 347, Hom 321 muaj Ti, ib qho tseem ceeb alloying caij, thiab Hom 347 muaj Nb, uas txhim kho cov intergranular corrosion kuj ntawm cov khoom.Nws yog tsim rau stainless hlau txheem qhov chaw uas tsis annealed tom qab vuam los yog nyob rau hauv kev pab cuam ntawm 420-1013 ° C.
