Qhov zoo ntawm Duplex Stainless Hlau
Txhim kho lub zog
Ntau qib duplex muaj ntau npaum li ob zaug muaj zog dua qib austenitic thiab ferritic stainless hlau.
High Toughness thiab Ductility
Duplex stainless hlau yog feem ntau formable nyob rau hauv siab tshaj ferritic qib thiab muab ntau toughness. Txawm hais tias lawv feem ntau muab cov nqi qis dua li cov hlau austenitic, cov qauv tshwj xeeb thiab cov yam ntxwv ntawm cov hlau duplex feem ntau tshaj qhov kev txhawj xeeb.
Siab Corrosion Resistance
Raws li qib hauv nqe lus nug, duplex stainless hlau muaj qhov sib piv (lossis zoo dua) corrosion kuj zoo li qib austenitic. Rau cov hlau uas muaj nitrogen ntxiv, molybdenum, thiab chromium, steels muaj kev tiv thaiv siab rau ob qho tib si crevice corrosion thiab chloride pitting.
Tus nqi siv tau
Duplex stainless hlau muab tag nrho cov txiaj ntsig saum toj no thaum xav tau qis qis ntawm molybdenum thiab npib tsib xee. Qhov no txhais tau hais tias nws yog qhov kev xaiv qis dua li ntau cov qib austenitic ntawm stainless hlau.Tus nqi ntawm duplex alloys feem ntau tsis tshua muaj zog dua li lwm cov qib steel ua rau nws yooj yim rau kwv yees tus nqi -- ob qho tib si nyob rau hauv pem hauv ntej thiab lub neej theem. .Lub zog siab dua thiab corrosion kuj txhais tau hais tias ntau qhov chaw ua los ntawm duplex stainless tuaj yeem ua nyias dua li lawv cov austenitic counterparts muab cov nqi qis dua.
Lub ntsiab kom zoo dua ntawm duplex stainless hlau yog nws lub peev xwm los muab kev ua tau zoo heev ntawm cov nqi sib piv nrog ntau yam alloys. Ntawm nws tus nqi taw tes, tsis muaj lwm txoj hauv kev uas tuaj yeem phim nws lub zog siab thiab zoo heev corrosion kuj.
Duplex stainless hlau yog ua raws li kev sib xyaw microstructure ntawm austenite thiab ferrite. Lawv muab cov khoom zoo tshaj plaws ntawm austenitic stainless hlau (zoo corrosion kuj, zoo cuam tshuam toughness, npaj fabrication) thiab ferritic stainless hlau (siab zog, tsis kam mus rau kev nyuaj siab corrosion cracking) whilst limiting cov ntsiab lus ntawm kim alloying ntsiab xws li npib tsib xee thiab molybdenum.
