Duplex S32304 S32205 S32750 Stainless hlau yeeb nkab
Duplex stainless hlau yog cov tsis tshua muaj corrosion-resistant, ua hauj lwm-hardenable alloys. Lawv microstructure muaj kev sib xyaw ntawm austenite thiab ferrite theem. Yog li, duplex stainless hlau nthuav tawm cov yam ntxwv ntawm austenitic stainless hlau thiab ferritic stainless hlau.
2205 Duplex Stainless Hlau Yeeb Nkab
Duplex Pipe Specification
Duplex s32205 yeeb nkab yog tsim los ntawm kev sib xyaw ntawm austenitic thiab ferritic stainless hlau. Kev sib xyaw ntawm ob qhov tshwj xeeb alloys muab qib no nrog kev ua haujlwm zoo thiab lub zog. S32304 (2304) yog ib tug duplex stainless hlau uas muaj 22.5% Cr, 3% Nickel, thiab Mo. Alloy 2304 muaj zoo corrosion kuj rau316L. Super duplex stainless hlau S32750 muaj qhov ua haujlwm siab heev rau kev txhim kho hauv zos hauv chloride media thiab muaj zog txhua yam. Nws kuj muaj qhov sib npaug ntawm qhov sib npaug ntawm tus nqi PREN ntawm ntau dua 40, thiab qhov tsawg kawg tau lees paub qhov muaj zog ntawm 550 MPa, tso cai rau kev tsim qauv tsim hauv kev siv cov kabmob load.
