Dab tsi yog inconel 690 # Inconel 690
Cov ntaub ntawv rau cov cua kub hloov cov raj ntawm cov tshuab hluav taws xob hauv PWR nuclear fais fab nroj tsuag tau dhau los ntawm txoj kev txhim kho, suav nrog 304 austenitic stainless hlau, 600 alloy, 800 alloy thiab 690 alloy. Kev tshawb fawb ntawm corrosion tsis ua hauj lwm ntawm 600 alloy nyob rau hauv cov kev pab cuam qhia tau hais tias intergranular corrosion thiab intergranular kev nyuaj siab corrosion cracking yog lub ntsiab teeb meem. Alloy 690 yog siv los ua cov khoom siv hluav taws xob hloov hluav taws xob rau cov tshuab hluav taws xob hauv PWR nuclear fais fab nroj tsuag. Txij li thaum nws tau muab tso rau hauv lub xyoo 1990s, tsis muaj kev puas tsuaj, thiab cov nyhuv zoo heev.
Cov khoom siv: bar, yeeb nkab, phaj, nplhaib, forging
