Authentic 316L stainless hlau yeeb nkab nrog guaranteed khoom
316 stainless hlau yeeb nkab yog ib hom hollow ntev round steel, uas yog dav siv nyob rau hauv industrial kis pipelines thiab mechanical structural Cheebtsam xws li roj av, tshuaj kev lag luam, kev kho mob, khoom noj khoom haus, lub teeb kev lag luam, machinery thiab cov twj paj nruag, thiab lwm yam. qhov dabtsi yog khoov thiab torsional lub zog yog tib yam, qhov hnyav yog lub teeb, yog li nws kuj tau siv dav hauv kev tsim cov khoom siv tshuab thiab cov qauv engineering. Nws kuj yog siv los tsim ntau yam riam phom, chim, plhaub, thiab lwm yam. Ntau yam: 316 stainless hlau yeeb nkab, 316 stainless hlau ci yeeb nkab, 316 stainless hlau hniav yeeb nkab, 316 stainless hlau capillary, 316 stainless hlau welded yeeb nkab, 304 stainless hlau yeeb nkab.
Qhov siab tshaj plaws carbon ntsiab lus ntawm 1316l stainless hlau yeeb nkab yog 0.03, uas yuav siv tau nyob rau hauv daim ntawv thov uas annealing tsis tuaj yeem nqa tawm tom qab vuam thiab siab tshaj corrosion kuj yuav tsum tau. 316 stainless hlau yeeb nkab muaj cov ntsiab lus siab tshaj plaws ntawm 0.03 thiab tuaj yeem siv rau hauv cov ntawv thov uas tsis tuaj yeem nqa tawm tom qab vuam thiab qhov siab tshaj plaws corrosion yuav tsum tau.
316 thiab 317 stainless hlau (saib hauv qab no rau cov khoom ntawm 317 stainless hlau) yog molybdenum uas muaj cov hlau tsis huv.
Tag nrho cov kev ua tau zoo ntawm cov hlau no zoo dua li 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 phaj, tseem hu ua 00Cr17Ni14Mo2, corrosion kuj:
Qhov kev tiv thaiv corrosion zoo dua li 304 stainless hlau thiab muaj kev tiv thaiv corrosion zoo hauv kev tsim cov pulp thiab ntawv.
Carbide nag lossis daus tsis kam ntawm 316 stainless hlau yog zoo dua li ntawm 304 stainless hlau, thiab qhov kub thiab txias saum toj no tuaj yeem siv tau.
Stainless hlau yeeb nkab yog ib hom hollow ntev round steel, uas yog dav siv nyob rau hauv industrial kis pipelines xws li roj av, tshuaj kev lag luam, kev kho mob, khoom noj khoom haus, lub teeb kev lag luam, mechanical instruments thiab mechanical structural Cheebtsam. Tsis tas li ntawd, thaum lub zog khoov thiab torsional zoo ib yam, qhov hnyav yog lub teeb, yog li nws kuj tau siv dav hauv kev tsim khoom ntawm cov khoom siv tshuab thiab cov qauv tsim. Nws kuj yog siv los tsim ntau yam riam phom, phom, plhaub, thiab lwm yam. Cov yeeb nkab steel no tuaj yeem muab faib ua stainless hlau seamless steel yeeb nkab thiab stainless hlau welded steel yeeb nkab (slotted yeeb nkab). Raws li cov txheej txheem tsim khoom sib txawv, nws tuaj yeem muab faib ua ob peb hom: kub dov, extrusion, txias kos duab thiab txias dov. Raws li cov duab seem, nws tuaj yeem muab faib ua cov yeeb nkab thiab cov yeeb nkab tshwj xeeb. Lub voj voog steel yeeb nkab yog dav siv, tab sis kuj tseem muaj qee qhov square, rectangular, semicircular, hexagonal, equilateral triangle Octagonal thiab lwm yam tshwj xeeb-zoo li stainless hlau kav.
Kev ntsuam xyuas hydraulic yuav tsum tau ua rau cov yeeb nkab steel bearing kua siab los ntsuas nws qhov kev ua haujlwm siab thiab zoo. Nws yog qhov tsim nyog yog tias tsis muaj qhov xau, ntub dej lossis nthuav dav raws li qhov ntsuas siab. Qee cov yeeb nkab steel kuj tseem yuav raug kuaj crimping, kuaj flaring thiab flattening xeem raws li tus qauv lossis cov kev xav tau ntawm tus neeg thov.
304L stainless hlau yeeb nkab belongs rau thoob ntiaj teb stainless hlau cim txoj kev. 304L stainless hlau yeeb nkab - S30403 (AISI, ASTM)
Lub npe suav suav nrog 304L yog 00Cr19Ni10
Cov yam ntxwv thiab daim ntawv thov: steel nrog qis carbon cov ntsiab lus tshaj 0Cr19Ni9 muaj superior intergranular corrosion kuj. Nws yog ib feem tsis muaj kev kho cua sov tom qab vuam.
Numbering thiab sawv cev ntawm steel
① Cov cim tshuaj lom neeg thoob ntiaj teb thiab cov cim hauv tebchaws tau siv los sawv cev cov tshuaj muaj pes tsawg leeg, thiab cov ntawv Arabic yog siv los sawv cev cov ntsiab lus:
Piv txwv li: Tuam Tshoj, Russia 12CrNi3A
②International stainless hlau marking txoj kev: siv cov zauv tas los sawv cev steel series los yog tooj; Piv txwv li, Tebchaws Asmeskas, Nyiv, 300 series, 400 series thiab 200 series; Lub koom haum American Iron thiab Steel siv peb tus lej txhawm rau txheeb xyuas ntau qib txheej txheem ntawm malleable stainless hlau. Ntawm lawv, austenitic stainless hlau yog qhia los ntawm cov lej ntawm 200 thiab 300 series, thiab ferritic thiab martensitic stainless hlau yog qhia los ntawm cov lej ntawm 400 series. Stainless hlau, nag lossis daus hardening stainless hlau thiab siab alloy nrog cov ntsiab lus hlau tsawg dua 50% feem ntau yog siv lub npe patent lossis lub npe lag luam.
③ Tus lej xov tooj yog tsim los ntawm cov ntawv Latin thiab kev txiav txim, uas tsuas yog qhia lub hom phiaj.
Ntxiv mus, 316 stainless hlau kuj tseem tiv taus dej hiav txwv thiab kev ua haujlwm hnyav. 316 stainless hlau muaj qhov zoo oxidation tsis kam nyob rau hauv intermittent siv nrog kub tsis kam qis dua 1600 ℃ thiab siv tas li hauv qab 700 ℃.
Nyob rau hauv qhov ntau ntawm 800-1575 degrees, nws yog qhov zoo dua tsis txhob ua tsis tu ncua ntawm 316 stainless hlau, tab sis thaum 316 stainless hlau txuas ntxiv siv sab nraud qhov kub thiab txias, cov hlau tsis muaj cua sov zoo. Carbide nag lossis daus tsis kam ntawm 316L stainless hlau yog zoo dua li ntawm 316 stainless hlau, thiab qhov kub siab tshaj plaws tuaj yeem siv tau.
