Cua sov thiab Pickling
Zoo li lwm cov nickel alloys, alloy 690 yuav tsum huv si ua ntej nws yuav tsum tau rhuab thiab yuav tsum tau rhuab nyob rau hauv ib tug tsawg-sulfur cua.Rauv cua sov rau qhib cua sov yuav tsum tau txo me ntsis kom tsis txhob oxidation ntau dhau ntawm cov khoom.
INCONEL alloy 690 yog ib qho khoom siv-soluble alloy thiab tsis tuaj yeem ua los ntawm kev kho cua sov.Lub alloy feem ntau yog siv nyob rau hauv lub annealed mob.
Kev tsim
Qhov kub ntau rau kev kub hnyav ntawm INCONEL alloy 690 yog 1900 txog 2250 ° F (1040 txog 1230 ° C).Lub teeb tsim tuaj yeem ua tiav ntawm qhov kub thiab txias mus rau 1600 ° F (870 ° C).
Microstructure
INCONEL alloy 690 yog austenitic, solid-solution alloy nrog rau qib siab ntawm metallurgical stability.Cov hlau tsis tshua muaj solubility rau carbon, thiab nws cov microstructure feem ntau muaj carbides.Qhov loj carbide tam sim no nyob rau hauv cov hlau yog M23C6;qhov kev nplua nuj ntawm cov theem sib txawv nrog cov ntsiab lus carbon thiab thermal raug ntawm cov khoom.Lwm cov theem tam sim no yog titanium nitrides thiab carbonitrides.Tsis muaj embrittling intermetallic theem xws li sigma theem tau raug txheeb xyuas nyob rau hauv alloy 690.
