Dab tsi yog stainless hlau hlau?
Stainless hlau hlau, tseem hu uastainless hlau hlau, yog ntau yam khoom siv lo lo ntxhuav ntawm cov khoom sib txawv thiab cov qauv ua los ntawm cov hlau tsis muaj steel. Cov hlau uas tau kos los ntawm cov hlau tsis muaj steel muaj qhov ntev thiab qhov chaw du, thiab cov khoom siv kos duab thiab cov pwm siv tau yooj yim thiab yooj yim los tsim.
Dab tsi yog cov txheej txheem ntawm stainless hlau xaim?
Hlau hlau yog ib qho ntawm plaub yam loj ntawm cov hlau xws li daim hlau, cov raj, cov duab, thiab cov xov hlau. Nws yog cov khoom siv rov ua dua tshiab ua los ntawm cov khoom siv kub-dov hlau rods thiab txias-draw. Raws li tus ntoo khaub lig-sectional duab, muaj feem ntau yog puag ncig, square, duab plaub, daim duab peb sab, elliptical, tiaj tus, trapezoidal, Z-puab, thiab lwm yam; Raws li qhov loj me, muaj kev nplua ntxiv<0.1 mm, thinner 0.1~0.5 mm, thin 0.5~1.5 mm, medium 1.5~3.0 mm, thick 3.0~6.0 mm, thicker 6.0~8.0 mm, extra thick >8.{1}} hli; cais los ntawm kev siv zog, muaj tsawg siv<390 MPa, lower intensity 390~785 MPa, and ordinary intensity 785~1225 MPa, higher intensity 1225~1960 MPa, high intensity 1960~3135 MPa, extra high intensity >3135 MPa ua.
Muab faib los ntawm kev siv: zoo tib yam steel hlau xws li steel hlau rau vuam rods, ntsia hlau ua, mesh ua, ntim thiab luam ntawv industries, txias upsetting steel hlau rau txias taub hau rivets, screws, thiab lwm yam. Hluav taws xob cov hlau muaj xws li zus tau tej cov overhead kev sib txuas lus kab, steel. core aluminium strands Tshwj xeeb steel xov hlau rau xov, thiab lwm yam, steel hlau rau kev lag luam textile suav nrog daim npav combs, kho, daim npav cov khaub ncaws thiab rab koob xov hlau, hlua ua cov hlau xaim tshwj xeeb yog siv los tsim cov hlau xaim hlua thiab spokes, caij nplooj ntoos hlav steel. cov xov hlau muaj xws li lub caij nplooj ntoos hlav thiab caij nplooj ntoos hlav ntxhua khaub ncaws, pianos thiab log tsheb, cords thiab Steel xaim rau kev thauj cov kab xev, cov qauv steel hlau yog hais txog kev txiav steel hlau yooj yim hauv kev lag luam saib, pob bearings, thiab cov tshuab tsis siv neeg.Stainless hlau hlausuav nrog stainless hlau xaim rau cov hom phiaj saum toj no thiab phais kev cog hniav hlau. Resistance alloy hlau yog siv rau cov khoom siv cua sov thiab cov khoom tiv thaiv. Cov cuab yeej hlau suav nrog steel hlau thiab shoemaking hlau.
Lub xeev kev nyuaj siab ntawm kev kos duab hlau yog peb-dimensional kev nyuaj siab lub xeev ntawm ob-dimensional compressive stressive thiab ib tug tensile stress. Piv nrog rau qhov tseem ceeb ntawm lub xeev kev nyuaj siab ntawm compressive kev nyuaj siab nyob rau hauv peb cov lus qhia, lub kos hlau hlau yog ntau dua mus cuag ib tug yas deformation xeev. Lub xeev deformation ntawm daim duab yog peb-dimensional lub ntsiab deformation xeev ntawm ob qho kev qhia ntawm compression deformation thiab ib qho kev taw qhia ntawm tensile deformation. Lub xeev no tsis zoo rau plasticity ntawm cov ntaub ntawv hlau thiab feem ntau yuav tsim thiab nthuav tawm qhov tsis xws luag. Tus nqi deformation ntawm txhua qhov hla hauv cov txheej txheem hlau hlau yog txwv los ntawm nws qhov kev nyab xeeb. Qhov me me ntawm deformation npaum li cas, qhov ntau daim duab hla. Yog li ntawd, multi-pass nruam high-speed drawing yog feem ntau siv nyob rau hauv zus tau tej cov hlau nyob ntawm tej.
Classification ntawm stainless hlau hlau:
Feem ntau, raws li austenitic, ferritic, ob-txoj kev stainless hlau, thiab martensitic stainless hlau, nws yog tsuas yog muab faib ua 2-series, 3-series, 4-series, 5- series, thiab 6-series stainless hlau.
316 thiab 317 stainless hlau (saib hauv qab no rau kev ua haujlwm ntawm 317 stainless hlau) yog molybdenum-muaj stainless hlau. Cov ntsiab lus molybdenum hauv 317 stainless hlau yog me ntsis siab dua li ntawm 316 stainless hlau. Vim yog molybdenum nyob rau hauv cov hlau, tag nrho cov kev ua tau zoo ntawm cov hlau no zoo dua li ntawm 310 thiab 304 stainless hlau. Nyob rau hauv qhov kub thiab txias, thaum cov concentration ntawm sulfuric acid qis dua 15% thiab siab dua 85%, 316 Stainless hlau muaj ntau yam kev siv. 316 stainless hlau kuj tseem muaj kev tiv thaiv zoo rau cov tshuaj chloride corrosion, yog li nws feem ntau yog siv nyob rau hauv marine ib puag ncig. 316L stainless hlau muaj cov ntsiab lus siab tshaj plaws ntawm 0.03 thiab tuaj yeem siv rau hauv cov ntawv thov uas tsis tuaj yeem ua tom qab vuam thiab qhov siab tshaj plaws corrosion yuav tsum tau.
