Super duplex stainless xws li duplex yog cov khoom sib xyaw ua ke ntawm austenite thiab ferrite uas tau txhim kho lub zog dua li ferritic thiab austenitic steel qib. Qhov sib txawv tseem ceeb yog super duplex muaj cov ntsiab lus molybdenum thiab chromium siab dua uas ua rau cov khoom siv tiv taus corrosion ntau dua. Super duplex muaj cov txiaj ntsig zoo ib yam li nws cov neeg sib tw - nws muaj cov nqi tsim khoom qis dua thaum piv nrog cov qib ferritic thiab austenitic zoo sib xws thiab vim yog cov ntaub ntawv nce tensile thiab cov zis muaj zog, feem ntau qhov no muab rau tus neeg yuav khoom xaiv qhov kev xaiv txais tos ntawm kev yuav cov tuab me dua yam tsis tas yuav cuam tshuam rau qhov zoo thiab kev ua tau zoo.

Nta:
1. Kev tiv thaiv zoo rau kev xeb ntawm qhov pitting thiab crevice hauv dej hiav txwv thiab lwm yam chaw uas muaj chloride, nrog rau qhov kub thiab txias tseem ceeb tshaj 50 ° C
2. Kev ua haujlwm zoo heev thiab lub zog cuam tshuam ntawm ob qho tib si ambient thiab sub-zero kub
3. Kev tiv thaiv siab rau kev puas tsuaj, kev yaig thiab cavitation yaig
4. Kev tiv thaiv zoo heev rau kev ntxhov siab corrosion cracking hauv chloride muaj ib puag ncig
5. Kev pom zoo ntawm ASME rau daim ntawv thov lub nkoj siab
