GNEE muaj ntau tshaj 18 xyoo ntawm kev paub nyob rau hauv lub export ntawm stainless hlau. Peb muab 1.4507 txias dov stainless hlau tuav uas ua tau raws li cov qauv xws li EN 10088, ASTM A276 thiab ASTM A479. Peb muab cov kab puag ncig, square thiab hexagonal tuav, nrog rau cov kev pabcuam kev cai. Peb tus qauv diameters li ntawm 6mm txog 300mm. Peb muab kev kho solubilization, precision txias kos duab, tig, polishing (ci tag), dub xov thiab txiav cov kev pab cuam. Dimensional tolerances tuaj yeem ncav cuag h9 / h11, thiab peb kuj ua tiav CNC machining siab heev raws li cov duab kos.
Rau cov khoom txias txias ntawm UNS S32550 alloy, peb muab cov txheej txheem kev ntxhov siab tshem tawm raws li cov neeg siv khoom xav tau. Qhov kev kho no txo cov kev ntxhov siab uas tshwm sim los ntawm qhov txias txias yam tsis muaj kev cuam tshuam corrosion los yog qhov tseeb qhov tseeb.
Txias dov stainless hlau tuav (qib 1.4507) muab los ntawm GNEE raug xa mus rau hauv cov tshuaj annealed thiab ceev dej quenched mob. Peb nruj me ntsis tswj qhov kub dissolution thiab txias npaum li cas kom tsis txhob nag lossis daus ntawm cov teeb meem intermetallic theem (xws li sigma σ thiab chi χ theem). Qhov no lav qhov ruaj khov nyob rau hauv ob-theem microstructure, tshwj xeeb tshaj yog kev txhim kho pitting corrosion, crevice corrosion thiab chloride-induced stress corrosion cracking; Cov khoom uas nyob deb tshaj cov ntawm 2205 duplex steel thiab cov qauv 304 lossis 316L steels. Cov khoom tiv taus ntev yaig tshwm sim los ntawm seawater, brine thiab acidic desulfurization media, ua rau nws zoo tagnrho rau cov khoom raug rau siab loads thiab corrosive ib puag ncig, xws li twj tso kua mis, valve stems thiab fasteners rau marine daim ntaub ntawv.

Cov lus nug uas nquag nug
Dab tsi yuav tsum tau ceev faj thaum vuam 1.4507 steel tuav?
Vim nws lub zog siab thiab lub zog hnyav, nws raug nquahu kom siv cov cuab yeej coated carbide thiab qis txiav ceev. Rau vuam, sib xws super-duplex stainless hlau muab tub lim cov ntaub ntawv (xws li ER2594) yuav tsum tau siv thiab qhov kub thiab txias ntawm kev hla yuav tsum nruj me ntsis tswj (feem ntau pom zoo kom tsawg dua 150 degrees) kom tsis txhob embrittlement ntawm tshav kub-tshem tawm tsam.
Dab tsi yog qhov txawv ntawm 1.4507 thiab 2205 duplex steel?
1.4507 steel yog cais raws li "super duplex stainless hlau" thiab muaj PREN (Pinging Resistance Equivalence Number) ntau dua 40, thaum 2205 feem ntau muaj tus nqi ze rau 35. Nws yog ib qho tsim nyog sau cia tias 1.4507 muaj qhov sib ntxiv ntawm 1.5% thiab 2.5% tooj liab tiv thaiv. muaj zog reducers, xws li sulfuric acid thiab phosphoric acid, ua rau nws zoo dua lwm txoj rau 2205.
Qhov txawv ntawm 1.4507 thiab 1.4404 yog dab tsi?
1.4507 thiab 1.4404 yog ob qib sib txawv ntawm stainless hlau txhais los ntawm European tus qauv EN. Qhov sib txawv tseem ceeb yog 1.4404 yog cov hlau austenitic (feem ntau hu ua 316L) siv rau kev siv vuam thiab corrosion kuj, thaum 1.4507 yog cov hlau alloyed superduplex hlau, tsim los muaj zog heev thiab tiv taus cov chloride-nplua nuj ib puag ncig.
