Cov hlau tshwj xeeb hais txog cov hlau uas muaj cov khoom tshwj xeeb thiab siv. Duplex stainless hlau yog cov hlau tshwj xeeb, uas muaj ob theem ntawm austenite thiab ferrite. Austenite muaj qhov zoo corrosion kuj thiab siab zog, thaum ferrite muaj siab toughness thiab plasticity. Cov qauv duplex no ua rau duplex stainless hlau muaj cov khoom zoo heev, thiab tuaj yeem tswj tau zoo corrosion thiab lub zog nyob rau hauv qhov kub thiab txias thiab corrosive ib puag ncig. Yog li ntawd, duplex stainless hlau yog dav siv nyob rau hauv chemical kev lag luam, roj av, marine engineering, zaub mov ua thiab lwm yam teb kom tau raws li engineering xav tau nyob rau hauv tshwj xeeb ib puag ncig.
