1.4410 stainless hlau yeeb nkab yog dab tsi?
UNS S32750 (2507 Super Duplex Stainless Steel), tseem hu ua 1.4410 lossis SAF 2507, yog super duplex stainless hlau yeeb nkab khoom nrog microstructure muaj li ntawm 50% austenite thiab 50% ferrite. Nws muaj qhov tsawg kawg nkaus tawm lub zog txog li 530 MPa, uas yog ntau tshaj li ob zaug ntawm cov pa stainless hlau, tso cai rau kev sib zog thiab nyias cov qauv tsim. Nws yog dav siv nyob rau hauv seawater desalination, offshore roj thiab roj platforms, tshuaj ua, thiab pulp thiab ntawv industries rau cov khoom tseem ceeb xws li pipelines, tshav kub exchangers, twj, thiab li qub.
Dab tsi yog cov qauv rau 1.4410 stainless hlau kav?
1.4410 stainless hlau (tseem hu ua Super Duplex 2507, UNS S32750, lossis F53) cov kav dej feem ntau yog tswj hwm los ntawm cov qauv thoob ntiaj teb tsom rau siab - zog, corrosion- tiv taus, thiab siab - kev siv siab. Cov qauv tseem ceeb suav nrog ASTM A790 (seamless / welded yeeb nkab), ASTM A789 (tubing), thiab EN 10088-3 / EN 10216-5.

Dab tsi yog qhov txawv ntawm 1.4410 thiab 1.4462 (Duplex 2205)?
Lub pitting corrosion kuj ntawm 1.4410 (25% Cr) yog qhov siab dua li ntawm 1.4462 (22% Cr). Tsis tas li ntawd, lub zog ntawm 1.4410 yog kwv yees li 20% ntau dua li ntawm 1.4462. Txij li thaum 1.4410 muaj qib siab ntawm chromium thiab molybdenum, nws tus nqi feem ntau yog nyob ib ncig ntawm 30% siab dua li ntawm 1.4462.
1.4410 piv rau 904L (1.4539) li cas?
904L yog super- austenitic stainless hlau uas muaj kev tiv thaiv zoo heev rau sulfuric acid; Txawm li cas los xij, nws muaj lub zog qis dua thiab tsis zoo pitting corrosion kuj piv rau 1.4410. Hauv dej hiav txwv thiab siab - ib puag ncig siab, 1.4410 feem ntau muab cov nqi zoo dua -kev ua tau zoo thiab kev ua tau zoo dua li 904L.
Dab tsi yog qhov kev txwv kub rau 1.4410 stainless hlau kav?
Kev txwv siab: Nws raug pom zoo kom tsis pub tshaj 250℃- 280 degree, vim qhov kub siab tshaj qhov no tuaj yeem ua rau "475℃embrittlement," yog li txo cov khoom siv tawv.
Kev txwv qis dua: Nws pom zoo heev qis -kub toughness thiab feem ntau haum rau siv nyob rau hauv ib puag ncig mus rau -50℃.
