Super Duplex Stainless Hlau

 

Super Duplex Stainless Steel (DSS) yog hais txog stainless hlau uas ferrite thiab austenite txhua tus account rau li 50%. Feem ntau, cov ntsiab lus ntawm theem me me yuav tsum muaj tsawg kawg yog 30%. Hauv cov ntsiab lus C tsawg, cov ntsiab lus Cr yog 18% ~ 28% thiab Ni cov ntsiab lus yog 3% ~ 10%. Qee cov hlau kuj tseem muaj cov alloying xws li Mo, Cu, Nb, Ti, thiab N.

 

Cov hlau no muaj cov yam ntxwv ntawm ob qho tib si austenitic thiab ferritic stainless hlau. Piv nrog rau ferrite, nws muaj ntau dua plasticity thiab toughness, tsis muaj chav tsev kub brittleness, ho txhim kho intergranular corrosion kuj thiab vuam kev ua tau zoo, thaum tuav cov ntsiab lus hlau. Cov khoom stainless hlau yog nkig ntawm 475 degree, muaj thermal conductivity, thiab muaj superplasticity thiab lwm yam ntxwv. Piv nrog austenitic stainless hlau, nws muaj lub zog siab thiab txhim kho kev ua haujlwm zoo rau intergranular corrosion thiab chloride stress corrosion. Duplex stainless hlau muaj zoo heev pitting corrosion kuj thiab kuj yog ib tug nickel-txuag stainless hlau.
