ʻO ka kila kila fuplex

Ponoʻo Duplex Guilless Steel (DSS) e pili ana i ke kila Stiinless me Ferrite a me Austenti no kahi o 50% i kēlā me kēia papa liʻiliʻi e pono ai ma kahi o 30%. Ma keʻano o nāʻikepili haʻahaʻa,ʻo nā mea he 18% ʻO kekahi mau kila he mau kālā e like me ka m, cu, nb, ti, a me n.
ʻO ka steel fuplex i loaʻa i nāʻano hana hope loa:
(1) He molybdelu - loaʻa i kahi kila maikaʻi fuplex i ka cheelless maikaʻi loa i ka paleʻana i keʻano o ke kaumaha ma lalo o ke kaumaha haʻahaʻa. ʻO ka maʻamau, 18-8 Type Austevitic Inselless Steel ke kiʻi i ka style corrosion cusrosion checking ma luna o 60 ° C. ʻO nā mea hana wela, evaporators a me nā mea hana'ē aʻe i hanaʻia i kēiaʻano o keʻano o keʻano he chelfiden.
(2) He molybdelu - loaʻa i nā kila stielle fuplex I ka manawa e loaʻa ai keʻano like me ka helu kaulike likeʻole (CR% CR% + 3.3MO% + 16N%) ʻO ka paleʻana o ka corrosion e pale ana i ka steel fulex ʻO ka pitting a me Crevice Corrosioni e kū'ē ana i keʻano o ka chromit kiʻekiʻe o ka cheplex fuplex fuelless normal a he 25% cr,ʻoi aku ka nui o ka nitrogen,ʻoi aku ka nui o ka nitrogen.
(3) He momona maikaʻiʻo ia i ka paleʻana a me ka paleʻana i ke kū'ēʻana. Ma lalo o nā kūlana o nā'ōnaehana pili pono, kūpono ia no ka hanaʻana i nā pono mana e like me nā pumps a me nā vale.
(4) He mau mea maikaʻi maikaʻi nā mea ponoʻole. He ikaika kiʻekiʻe a me ka ikaika ikaika, aʻelua o kona ikaika iʻelua mau manawa he mau mea kila 18-8 austetetic. ʻO ka Ellingation i loko o ka moku'āina paʻa i kahi kūlana o ka'ōlelo a 25%, a me ka paʻakikī paʻakikī a AK (V-notch) ma luna o 100j).
) ʻO ka maʻamau,ʻaʻohe e koiʻia,ʻaʻole pono e koiʻia mua, aʻaʻohe pono wela e pono ai ma hope o ka weldo. Hiki ke hoʻopauʻia me nā mea e like me nā mea e like me 18-8 austetetitic stielless steel or carbon a carbon paha.
(6)ʻO keʻano o ka wela wela o Duplex Stielless Guelless Steel i kahi mea kūʻai haʻahaʻa haʻahaʻa haʻahaʻa Hiki ke neʻe pololeiʻia i loko o nā bilets e hana i nā papa kila i nā paleʻole o ke kalaʻoleʻana. ʻO ka hana wela o Dulex Insinless Steel i kahi kila kiʻekiʻe e loaʻa ana i nā cromium kiʻekiʻe
(7)ʻO ka hopena paʻakikī e hana i ka wā ma mua o ka hanaʻana ma mua o ka mea kila he 18-8 austenitic I keʻano mua o ka hanaʻana o nā tobes a me nā papa, he pono nui ke kumu nui e hoʻopiliʻia e hana.
(8) Hoʻohālikelikeʻia me nā kila kilatitic austevitic, heʻano nui a me kahi ākea o keʻano o ka mea hana e like me nā papa hana composite. Ua kūpono hoʻi ke kūpono i nā lole o nā loli wela, aʻo kona hoʻololiʻana eʻoi aku ka loli welaʻoi aku ka kiʻekiʻe o Austentic iʻoi aku.
(9) He mau mea likeʻoleʻo Britle o nā mea kūʻai aku o ka chromiticies kiʻekiʻe o ka cheritic kiʻekiʻe aʻaʻole kūpono no ka hoʻohanaʻana i nā kūlana hana ma luna o 300 ° C. ʻO ka haʻahaʻa o ka chromium i loko o ka mea kila fuplex, ka liʻiliʻi i nā mea he nui e like me ka Σ ia.
