Hais txog Alloy 904l Yeeb Nkab
Alloy 904L / UNS N08904 / 1.4539 yeeb nkab, super austenitic stainless hlau, muaj npe nrov rau nws qhov tshwj xeeb corrosion kuj nyob rau hauv ntau yam corrosive ib puag ncig, nrog rau cov uas muaj sulfuric acid, phosphoric acid, thiab chloride daws. Nws cov ntsiab lus chromium, npib tsib xee, thiab molybdenum ua rau nws tsis kam tiv thaiv ob qho tib si thiab hauv zos corrosion, ua rau nws nrhiav tau tom qab hauv kev lag luam xws li kev lag luam tshuaj, tshuaj, pulp thiab ntawv, thiab offshore roj thiab roj.
Kev qhia tshwj xeeb ASTM B677
- ASTM B677-04a 2017 Version: Txheem Specification rau UNS N08904, UNS N08925, UNS N08354, thiab UNS N08926 Seamless Yeeb thiab Tube.
- ASTM B677-21 2023 Version: Txheem Specification rau Nickel-Iron-Chromium-Molybdenum thiab Hlau-Nickel-Chromium-Molybdenum-Copper Seamless Yeeb thiab Tube.
ASTM B677, nyob rau hauv nws cov iterations yav dhau los, tau txais kev pab raws li tus qauv specification rau seamless kav thiab raj ua los ntawm alloys zoo liASTM B677 UNS N08904 Cov Lus Qhia(904L). Txawm li cas los xij, raws li ASTM International tau ua kom zoo dua nws cov ntsiab lus thiab cov txheej txheem saib xyuas, qee cov qhab nia tau muab rov qab rau cov kev qhia tshwj xeeb los txhim kho categorization thiab xyuas kom meej meej rau cov neeg siv khoom thiab cov chaw tsim khoom.
Specifications A269 thiab A312 / A312M
ASTM International tau txais kev txhais cov ntsiab lus uas qee cov qib, xws li UNS N08904 yav dhau los hauv cov lus qhia no, tau lees paub tias yog cov hlau tsis muaj steel, vim tias cov qib no muaj hlau ua cov khoom loj tshaj plaws los ntawm cov feem pua. Cov qib no yog nyob rau hauv kev saib xyuas ntawm ASTM Pawg A01 thiab nws cov pab pawg. Cov khoom ntawm N08904 yav dhau los tau them rau hauv qhov kev qhia tshwj xeeb tam sim no tau them los ntawm SpecificationsA269 thiab A312 / A312M.
Kev hloov pauv ntawm Alloy 904L kav mus rau ASTM A312 / A312M qhia txog kev sib koom tes los ntawm ASTM International kom ua raws li cov qauv kev xav tau ntawm kev lag luam thiab kev nce qib hauv kev lag luam.ASTM A312/A312Mmuab cov lus qhia dav dav rau seamless, welded, thiab hnyav hnyav ua haujlwm austenitic stainless hlau kav tsim nyog rau kev kub siab thiab kev pabcuam corrosive.
Nyob rau hauv cov nqe lus ntawm lub tswv yim, qhov kev hloov no txhais tau hais tias manufacturers thiab cov neeg siv ntawmAlloy 904L cov kav dejtuaj yeem xa mus rau ASTM A312 / A312M rau cov ncauj lus kom ntxaws, ua kom ua raws li cov qauv kev lag luam thiab ua kom yooj yim rau kev sib koom ua ke rau ntau yam kev siv. Los ntawm kev sib sau cov qhab nia cuam tshuam raws li cov qauv tshwj xeeb, ASTM International txhim kho kom pom tseeb thiab nkag mus tau yooj yim, thaum kawg txhawb kev ua tau zoo thiab kev ntseeg siab hauv kev xaiv cov khoom siv thiab kev siv thoob plaws ntau hom kev lag luam.
Rau cov neeg muaj feem koom nrog hauv kev tsim khoom, kev yuav khoom, thiab kev siv cov kav dej Alloy 904L, kev paub txog ASTM A312 / A312M yog qhov tseem ceeb rau kev ua kom zoo, kev ua tau zoo, thiab ua raws li cov kev cai tswj hwm. Kev ua raws li cov qauv kev qhia tshwj xeeb tsis tsuas yog ua kom yooj yim sib hloov ntawm cov ntaub ntawv tab sis kuj txhim kho kev sib tshuam thiab kev sib raug zoo hauv cov txheej txheem nyuaj thiab cov txheej txheem.
