Hom Stainless Hlau Cov Khoom Siv Thiab Cov Ntsiab Cai Xaiv Rau Fasteners

Fasteners yog feem ntau siv cov khoom hauv cov cuab yeej siv tshuab, nrog tus nqi siv ntau heev. Lawv feem ntau suav nrog screws, ceev, bolts, rivets, thiab lwm yam. txhawm rau ua kom muaj kev nyab xeeb ntawm kev siv fastener, peb muaj qee yam hauv kev xaiv cov khoom siv. Raws li peb cov kev paub txog kev siv fastener, Zhonghua Standard Parts Network qhia cov ntaub ntawv hais txog feem ntau siv stainless hlau cov ntaub ntawv rau fasteners thiab cov hauv paus ntsiab lus rau xaiv stainless hlau cov ntaub ntawv rau fasteners.

Lub hauv paus ntsiab lus ntawm kev xaiv cov ntaub ntawv stainless hlau rau fasteners feem ntau yuav tsum tau txiav txim siab los ntawm cov hauv qab no:
1. Kev xav tau rau cov khoom siv kho tshuab, tshwj xeeb tshaj yog lub zog, ntawm cov khoom siv fastener.
2. Cov kev xav tau ntawm kev ua haujlwm ntawm kev ua haujlwm corrosion ntawm cov ntaub ntawv.
3. Cov kev xav tau ntawm kev ua haujlwm kub ntawm qhov kub tsis kam (siab kub, lub zog, oxidation tsis kam) ntawm cov ntaub ntawv.
4. Cov kev xav tau ntawm cov khoom siv ua tau zoo raws li kev siv tshuab ntau lawm.
5. Lwm yam xws li qhov hnyav, tus nqi, thiab kev yuav khoom yuav tsum tau txiav txim siab.
Tom qab kev txiav txim siab zoo ntawm tsib yam no, lub hom phiaj, ntau yam, kev qhia tshwj xeeb, thiab cov qauv siv rau kev xaiv cov fasteners thaum kawg txiav txim siab.
Dab tsi yog cov khoom siv stainless hlau feem ntau siv rau fasteners?
1. 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. Ob qho tib si corrosion kuj thiab txhua yam khoom zoo sib xws. Lub ntsiab lus pib rau kev xaiv yog cov txheej txheem ntau lawm ntawm fasteners, uas nyob rau hauv lem nyob ntawm qhov loj thiab cov duab ntawm cov fasteners, raws li zoo raws li qhov ntau npaum li cas tsim.
Hom 302 yog siv rau cov ntsia hlau thiab tus kheej tapping bolts uas yog machined.
Hom 303 yog tsim los txhim kho kev ua tau zoo los ntawm kev ntxiv me me ntawm cov sulfur rau 303 stainless hlau, uas yog siv los ua cov txiv ntoo nrog cov khoom lag luam.
Hom 304 yog tsim rau kev ua haujlwmfastenerssiv cov cuab yeej kub taub hau, xws li cov lus qhia ntev dua thiab cov kab loj loj, uas tuaj yeem tshaj qhov kev siv tshuab txias taub hau.
Hom 305 yog tsim rau kev ua cov fasteners siv cov tshuab txias taub hau, xws li cov txiv ntoo txias thiab cov hexagonal bolts.
309 thiab 310 hom muaj Cr thiab Ni cov ntsiab lus siab dua 18-8 stainless hlau, ua rau lawv haum rau fasteners ua haujlwm ntawm qhov kub thiab txias.
316 thiab 317 hom, ob qho tib si muaj cov hlau alloying Mo, muaj qhov kub thiab txias zog thiab corrosion tsis kam tshaj 18-8 stainless hlau.
321 hom thiab 347 hom, 321 hom muaj qhov ruaj khov alloying caij Ti, thaum 347 hom muaj Nb, yog li txhim kho cov khoom tiv thaiv rau intergranular corrosion. Haum rau fasteners uas tsis annealed tom qab vuam los yog nyob rau hauv kev pab cuam ntawm 420 thiab 1013C.
2. Ferritic stainless hlau
430 hom zoo tib yam chromium hlau muaj qhov zoo dua corrosion thiab kub tsis kam tshaj 410 hom. Nws muaj hlau nplaum, tab sis nws tsis tuaj yeem ntxiv dag zog los ntawm kev kho cua sov. Nws yog tsim rau stainless hlau fasteners nrog me ntsis siab dua corrosion kuj thiab tshav kub tsis kam thiab dav siv zog yuav tsum tau.
3. Martensitic stainless hlau
Hom 410 thiab 416 tuaj yeem ua kom muaj zog los ntawm kev kho cua sov, nrog rau qhov nyuaj ntawm 35-45HRC thiab kev ua haujlwm zoo. Lawv yog siv los ua cua sov-resistant thiab corrosion-resistant fasteners rau kev siv dav. Hom 416 muaj cov ntsiab lus sulfur me ntsis thiab yog ib qho dawb txiav stainless hlau.
420 hom, leej faj cov ntsiab lus Ntau dua lossis sib npaug li 0.15%, txhim kho cov khoom siv kho tshuab, tuaj yeem ua kom muaj zog los ntawm kev kho cua sov, qhov siab tshaj plaws hardness tus nqi 53 ~ 58HRC, siv rau fasteners uas yuav tsum tau muaj zog.
4. Cov nag lossis daus hardening stainless hlau
17-4PH, PH15-7Mo, tuaj yeem ua tiav lub zog siab dua li cov qauv 18-8 stainless hlau thiab yog li siv rau lub zog siab, corrosion-resistant stainless hlau fasteners.
A-286, Nws yog cov hlau tsis muaj tus qauv uas muaj kev tiv thaiv corrosion ntau dua li feem ntau siv 18-8 stainless hlau, thiab tseem muaj cov khoom siv zoo ntawm qhov kub thiab txias. Siv los ua lub zog muaj zog, kub-resistant, thiab corrosion-resistant fasteners, kev khiav hauj lwm kub tuaj yeem ncav cuag 650-700C.
