He aha ka Inconel 690

Ma muli o ke kūpaʻa kūpaʻa kiʻekiʻe i ka media oxidizing acidic media, hiki ke hoʻohana ʻia e hana i ka waikawa nitric, acidic nitric + hydrofluoric acid a me nā pono hana ʻē aʻe.

ʻO nā mea hana no nā paipu hoʻoheheʻe wela o nā mea hana mahu i PWR nā mea kanu nukelea i hele i loko o kahi hanana hoʻomohala, e like me 304 austenitic mea kila kila, 600 oka hao, 800 oka a me nā huina 690. ʻO ka noiʻi e pili ana i ka maikaʻi ʻole o ka popo 600 o ka hana i ka lawelawe e hōʻike ana ʻo ka hoʻowahāwahā intergranular a me ka hoʻohaunaele stress intergranular nā pilikia nui. Hoʻohana ʻia ke kinikini 690 ma ke ʻano he paipu hoʻoili wela no nā mea hoʻoulu mahu i nā mea kanu mana nukelea PWR. Ma muli o ka hoʻohana ʻia i ka makahiki 1990, ʻaʻohe mea i hōʻike ʻia a maikaʻi loa ka hopena.
