1. Lub cev muaj zog
Lub cev muaj zog ntawm 202 thiab cov sib thooj 300 series steels nyob rau hauv cov tshuaj kho lub xeev, lub cev lub cev ntawm 200 series thiab 300 series yog yuav luag tib yam. Txawm li cas los xij, kev hloov pauv hauv permeability tom qab ua haujlwm txias yog txawv. Vim tias qhov sib txawv ntawm mutagenic martensite thaum ua haujlwm txias, qhov nce hauv permeability tsawg dua li ntawm 200 series thiab 300 series.
2. Mechanical cwj pwm
201 thiab 202 txawv ntawm lwm cov ntaub ntawv 200 series. Zoo li 301 thiab 302, lawv yog tag nrho cov metastable austenitic stainless hlau uas muaj zog ua haujlwm ntau dua. Cov hlau no muaj kev ua haujlwm hardening nkhaus. 201 thiab 301 thiab 202 thiab 302 muaj cov yam ntxwv zoo sib xws. 201,301 Ua haujlwm hardenability ntau dua. Tus nqi ntawm martensite tsim yog txawv rau txhua qib. 202,304 martensite tsim tsawg heev, thiab ua hauj lwm hardening feem ntau nyob ntawm deformity. Rau cov hlau qis dua 204 thiab 204L, yuav luag txhua qhov kev ua haujlwm hardening nyob ntawm kev sib txawv. Cov khoom siv kho tshuab thiab permeability ntawm CrMnN series cov ntaub ntawv tau qhia nyob rau hauv Table 5. Lub hardness ntawm cov steels nyob rau hauv cov tshuaj kho lub xeev yog hais txog HV250, thiab lub zog tom qab txias-rolling hardening yog siab dua, thiab cov Hv tuaj yeem ncav cuag 500, tab sis cov permeability. tseem qis dua 1.005 hauv lub xeev no.
Kev thov:
202 stainless hlau yeeb nkab belongs rau 200 series. Kev txhim kho thaum ntxov hloov 18-8 chromium-nickel austenitic stainless hlau nrog manganese thiab nitrogen es tsis txhob npib tsib xee. 18-8 hom Cr-Ni stainless hlau 301, 302, 304 (xws li 321) suav nrog ntau dua 50% ntawm tag nrho cov khoom tsim tawm ntawm stainless hlau. Cov qib steel no muaj cov khoom zoo heev xws li kev tiv thaiv corrosion, cov khoom siv kho tshuab, cov khoom kub thiab tsis kub, cov txheej txheem, thiab cov khoom zoo nkauj. Lawv tau dav siv nyob rau hauv ntau yam teb los ntawm pej xeem mus rau tub rog thiab pej xeem architectural kho kom zoo nkauj. Cov khoom siv hauv tsev, khoom siv hauv chav ua noj thiab khoom siv, kev thauj mus los, kev tiv thaiv ib puag ncig, kev tsim kho hauv nroog; tub rog aviation, aerospace, nuclear kev lag luam, nkoj; industrial fields ntawm tshuaj, chiv, roj av, textile, luam ntawv, ntawv, zog. Table 1 teev cov AISI200 series ntawm tus qauv manganese-muaj austenitic stainless hlau. Yog li kev tshawb fawb thaum ntxov ntawm 201, 202, 204, 205, 206 yog sib haum rau Cr-Ni series 301, 302, 304, 305, 316. Tom ntej, 211 tau tsim los siv cov qib qis carbon nitrogen, Mn, thiab Cu-ntxiv qib steel. rau kev ua haujlwm txias. 201L, 201LN, thiab lwm yam yog kev txhim kho ntawm 201 los daws qhov teeb meem ntawm intergranular stress corrosion.
High-nitrogen CrMnN austenitic stainless hlau muaj lub zog siab, toughness, siab hnav tsis kam, tsis muaj hlau nplaum, corrosion kuj thiab lwm yam ntxwv, thiab muaj ntau yam kev xav tau hauv kev lag luam. Nyob rau hauv lub neej yav tom ntej, yuav muaj kev txhim kho ntau dua hauv cov hauv qab no:
1. Lub high-nitrogen CrMnNiN steel nrog lub zog siab, siab corrosion kuj thiab zoo kub tsis tshua muaj siab toughness yuav siv tau rau aircraft, aerospace thiab ships nrog zoo heev kev ua tau zoo rods, xov hlau, forgings, nruab nrab daim hlau, thiab nyias daim hlau los ua ntim, kav, valves, Cables, thiab lwm yam.
2. Hnav-tiv taus, corrosion-resistant, high-toughness thiab high-nitrogen CrMnN austenitic stainless hlau tuaj yeem muab cov khoom siv corrosion-resistant, hnav-resistant mechanical khoom thiab cov khoom siv rau cov khoom siv mining rau kev lag luam mining.
3. Tsis muaj hlau nplaum, muaj zog, corrosion-resistant, high-nitrogen CrMnMoN austenitic stainless hlau, uas muaj peev xwm muab cov tsis sib nqus laum dab tshos rau cov roj teb, thiab cov khoom tsis sib nqus guard rings rau lub tshuab fais fab nroj tsuag. 4. High pitting kuj, crevice corrosion kuj thiab siab nitrogen CrNiMnMoN Austenitic stainless hlau tuaj yeem muab cov ntaub ntawv rau seawater heat exchangers, seawater desalination khoom, thiab flue gas desulfurization li nyob rau hauv ntug dej hiav txwv factories.
