Nickel 200 (UNS N02200) thiab 201 (UNS N02201) yog dual-certifiable wrought nickel cov ntaub ntawv. Lawv txawv tsuas yog nyob rau hauv qhov siab tshaj plaws carbon qib tam sim no - 0.15% rau Nickel 200 thiab 0.02% rau Nickel 201.
Nickel 200 phaj feem ntau txwv rau kev pabcuam ntawm qhov kub qis dua 600ºF (315ºC), txij li thaum kub siab dua nws tuaj yeem raug kev txom nyem los ntawm graphitization uas tuaj yeem cuam tshuam loj heev. Thaum kub siab dua Nickel 201 phaj yuav tsum tau siv. Ob qib raug pom zoo raws li ASME Boiler thiab Pressure Vessel Code Tshooj VIII, Division 1. Nickel 200 phaj tau pom zoo rau kev pabcuam txog 600ºF (315ºC), thaum Nickel 201 phaj tau pom zoo txog 1250ºF (677ºC).
Ob qib muab kev tiv thaiv zoo rau cov dej qab zib caustic thiab lwm yam alkalis. Cov alloys ua tau zoo tshaj plaws hauv kev txo qis ib puag ncig tab sis kuj tseem tuaj yeem siv nyob rau hauv oxidizing tej yam kev mob uas tsim ib tug passive oxide zaj duab xis. Lawv ob leeg tiv thaiv corrosion los ntawm distilled, dej ntuj thiab ntws seawater tab sis raug tawm tsam los ntawm cov dej hiav txwv stagnant.
Nickel 200 thiab 201 yog ferromagnetic thiab nthuav tawm cov khoom siv hluav taws xob zoo nyob thoob plaws qhov kub thiab txias.
Ob qib tau yooj yim welded thiab ua tiav los ntawm cov txheej txheem khw fabrication.
