Kev Tsim Khoom:
Cov hlau stainless hlau hu ua duplex hauv nws cov khoom khov kho ntawm ferrite theem thiab austenite ntsib txhua ib nrab, feem ntau cov ntsiab lus tsawg dua kuj yuav tsum ncav cuag 30%. Yog tias cov ntsiab lus C qis, Cr ntawm 18% txog 28%, Ni ntawm 3% txog 10%. Qee cov hlau kuj muaj Mo, Cu, Nb, Ti, N thiab lwm yam khoom sib xyaw.
Cov txiaj ntsig.
Cov hlau muaj cov yam ntxwv ntawm austenitic thiab ferritic stainless hlau,
1. Piv nrog rau ferrite, plasticity, toughness siab dua, tsis muaj qhov kub thiab txias brittleness, tiv taus intergranular corrosion thiab vuam kev ua tau zoo dua, thaum tseem tswj tau hlau. Cov hlau tsis xeb uas tsim nyog 475 ℃ brittleness thiab thermal conductivity siab, nrog superplasticity thiab lwm yam.
2. Piv nrog rau cov hlau tsis xeb austenitic, lub zog siab thiab tiv taus intergranular corrosion thiab tiv taus chloride kev ntxhov siab corrosion tau zoo dua qub.
3. Duplex stainless hlau muaj kev tiv thaiv zoo heev rau kev tiv thaiv xeb pitting, tab sis kuj yog ib feem ntawm nickel stainless hlau.
