Cov hlau tsis xeb yog cov hlau sib xyaw ua ke nrog qhov chaw du, weldability siab, corrosion tsis kam, polishing tsis kam, kub tsis kam, corrosion tsis kam thiab lwm yam ntxwv. Nws yog dav siv hauv ntau yam lag luam thiab yog ib qho khoom siv tseem ceeb hauv kev lag luam niaj hnub no. Cov hlau tsis xeb yog muab faib ua austenitic stainless hlau, ferritic stainless hlau, martensitic stainless hlau, thiab duplex stainless hlau raws li lub xeev qauv.Cov Hlau Stainless Austenitic: hlau tsis xeb nrog cov qauv austenitic ntawm chav sov. Hlau muaj Cr≈18%, Ni≈8% -25% thiab C≈0.1%. Hlau muaj kev tawv thiab plasticity siab, tab sis lub zog qis.Martensitic Stainless Hlau: Ib hom hlau uas nws cov khoom siv kho tshuab tuaj yeem hloov kho los ntawm kev kho cua sov. Nws muaj lub zog thiab kev tawv sib txawv ntawm qhov kub sib txawv.Ob chav Stainless hlauAustenitic thiab ferrite txhua tus suav txog ib nrab ntawm cov qauv. Thaum cov ntsiab lus C qis, cov ntsiab lus Cr yog 18% txog 28%, thiab cov ntsiab lus Ni yog 3% txog 10%. Qee cov hlau kuj muaj cov khoom sib xyaw xws li Mo, Cu, Si, Nb, Ti, thiab N. Hom hlau no muaj cov yam ntxwv ntawm austenitic thiab ferritic stainless hlau.Ferritic Stainless Hlau: Nws muaj 15% txog 30% chromium thiab muaj lub cev-centered cubic siv lead ua qauv. Cov hlau no feem ntau tsis muaj nickel, thiab qee zaum muaj me ntsis Mo, Ti, Nb thiab lwm yam ntsiab lus. Cov hlau no muaj cov yam ntxwv ntawm cov thermal conductivity loj, me me expansion coefficient, zoo oxidation tsis kam, thiab zoo heev kev ntxhov siab corrosion tsis kam.
