Tsim cov qauv ASME B36.10 ASME B36.49
UNTED S2750 SUPER DUPLEX Fasteners muaj qhov zoo weldability thiab tuaj yeem koom nrog nws tus kheej lossis cov roj hlau arc vuam, flux cored hlau lossis subsbreaked arc vuam.
Super Duplex s32760 Sawb sib npaug rau Werkstoff tus naj npawb DIN 1.4501, thermal conductivity 12.8 w \ / m, cov tub ntxhais hluas modulus 189k mpa. Nws muaj cov txiaj ntsig lub zog ntawm 550 MPA thiab lub hardness ntawm 270 HB. Unr unrux perfleX perforated daim ntawv yog kub tensile lub zog ntawm 834 MPa thiab elongation ntawm 36% ib 2 ntiv tes ntev. Duplex steel s32760 daim ntawv tau txais nws lub npe los ntawm nws ob-theem microstructure ntawm ferrite thiab austenite. piv. Cov khoom siv ntawm cov alloy no muaj qhov sib npaug ferrite-Austenite piv ntawm txog 100 rau cov khoom siv tau zoo. 50 \ / 50. Daim ntawv qhia txog lub hnab yas S32760 muaj los ntawm Mahabali (Mahabali tau muab los ntawm Mahabali yog tam sim no dav siv cov khoom siv tau zoo tshaj plaws thiab muaj cov khoom lag luam muaj feem xyuam. Nws muaj cov pitting zoo tshaj plaws thiab crevice corrosion tsis kam piv rau S32205. Qhov no sa sa sa 240 undow s32760 gasket txhawb nqa cov tshuabnability ntawm kev kub siab los ntawm 950 txog 1150 degrees Celsius. Tab sis qhov kev siv tam sim ntawd nce qis dua 900 degrees Celsius. Txawm li cas los xij, txias ua haujlwm yuav tsum muaj kev ntxhov siab tsis kam.
