he aha ka inconel 690#Inconel 690
ʻO nā mea hana no nā paipu hoʻoili wela o nā mea hana mahu i nā mea kanu nuklea PWR ua hele ma ke kaʻina hana hoʻomohala, me ka 304 austenitic stainless steel, 600 alloy, 800 alloy a me 690 alloy. Ke hōʻike nei ka noiʻi e pili ana i ka hiki ʻole o ka corrosion o 600 alloy i ka lawelawe ʻana i ka intergranular corrosion a me ka intergranular stress corrosion crack nā pilikia nui. Hoʻohana ʻia ʻo Alloy 690 ma ke ʻano he mea hoʻoheheʻe wela no nā mea hana mahu i nā mea kanu nuklea PWR. Mai ka hoʻohana ʻia ʻana i ka makahiki 1990, ʻaʻohe pōʻino i hōʻike ʻia, a maikaʻi loa ka hopena.
ʻO ke ʻano huahana: bar, pipe, plate, apo, forging
