Kuhili ʻole 904 / 904L
Nā inoa kālepa maʻamau: Alloy 904L ,N08904 , W.Nr1.4539 ,N08904 ,Cr20Ni25Mo4.5Cu
ʻO 904L kahi mea kila kila maikaʻi loa me ke kalapona haʻahaʻa.Hoʻohana ʻia ka papa no ka hoʻohana ʻana ma lalo o nā kūlana corrosive koʻikoʻi.Ua hoʻohana ʻia i nā makahiki he nui a ua hoʻomohala mua ʻia e pale i ka corrosion i loko o ka waika sulfuric dilute.Hoʻonohonoho ʻia a ʻae ʻia no ka hoʻohana ʻana i ka moku kaomi ma kekahi mau ʻāina.Ma ke ʻano, he austenitic piha ka 904L a ʻaʻole maʻalahi i ka ua ferrite a me nā ʻāpana sigma ma mua o nā māka austenitic maʻamau me ka molybdenum kiʻekiʻe.ʻO ke ʻano, ma muli o ka hui pū ʻana o nā mea kiʻekiʻe o ka chromium, nickel, molybdenum a me ke keleawe 904L he kūpaʻa maikaʻi i ka corrosion maʻamau, ʻoi loa i nā kūlana sulfuric a me phosphoric.

Alloy 904L Nā Kūlana a me nā kikoʻī
ASME SB-625, ASME SB-649, ASME SB-673, ASME SB-674, ASME SB-677
ʻO Alloy 904L nā huahana i loaʻa ma Sekonic Metals
Alloy 904L Bar & Rods
Nā lāʻau pōʻai/Paʻa paʻa/Paʻa Hex,Nui Mai 8.0mm-320mm, Hoʻohana ʻia no nā bolts, fastners a me nā ʻāpana ʻokoʻa ʻē aʻe
Uea huila 904L
Hoʻolako ʻia ma ka uea kuʻi a me ka uea puna ma ke ʻano coil a ʻoki ʻia ka lōʻihi.
Alloy 904L pepa a me ka pā
ʻO ka laulā a hiki i 1500mm a me ka lōʻihi a hiki i 6000mm, Mānoanoa mai 0.1mm a 100mm.
Alloy 904L paipu ʻole a me Welded paipu
Hiki ke hana ʻia ka nui maʻamau a me ka nui i hoʻopili ʻia e mākou me ka hoʻomanawanui liʻiliʻi
Alloy 904L strip & coil
ʻO ke kūlana palupalu a me ke kūlana paʻakikī me ka ʻili ʻālohilohi AB, ka laulā a hiki i 1000mm
Alloy 904L mea paa
Alloy 904L mau mea i loko o nā ʻano Bolts, screws, flanges a me nā mea wikiwiki ʻē aʻe, e like me ka kikoʻī o nā mea kūʻai aku.
No ke aha ʻo Alloy 904L?
•Kūleʻa maikaʻi i ka corrosion lua a me ka corrosion crevice
•Kiʻekiʻe kū'ē i stress corrosion māwae, intergranular, maikaʻi machinability a weldability
•Ma nā ʻano ʻano like ʻole o ka phosphates904L alloy corrosion resistance ʻoi aku ka maikaʻi ma mua o ke kila kila maʻamau.
•I loko o ka ikaika oxidizing nitric acid, i hoʻohālikelike ʻia me ke kila kiʻekiʻe me ka ʻole o ke kila molybdenum, 904L hōʻike i ke kūpaʻa haʻahaʻa haʻahaʻa.
•ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion ma mua o ke kila stainless maʻamau.
•E ho'ēmi i ka nui o ka corrosion o ka lua a me nā āpau no ke kiʻekiʻe o ka nickel, a loaʻa ke kū'ē maikaʻi i ka corrosion stress.ka pohā, i loko o ke kaiapuni o ka chloride solution, ka hoʻopaʻa ʻana o ka solution hydroxide a me ka hydrogen sulphide waiwai.
Alloy 904L kahua noi:
•ʻO ka ʻaila a me nā mea hana petrochemical, e like me ka reactor o nā lako petrochemical, etc.
•ʻO ka mālama ʻana i ka waika sulfuric a me nā mea halihali, e like me nā mea hoʻololi wela, etc.
•ʻO ka mana o ka mea hoʻoheheʻe kinoea desulfurization devicen, ʻO nā ʻāpana nui o ka hoʻohana: ke kino o ka hale kiaʻi absorber, flue, nā ʻāpana o loko, ka ʻōnaehana spray, etc.
•Organic acid scrubber a me ka peʻahi i ka ʻōnaehana hana.
•ʻO ka hale hoʻomaʻemaʻe wai, ka mea hoʻololi wela wai, nā mea hana pepa, ka waikawa sulfuric, nā mea hana wai nitric, ka waikawa,
•ʻO ka ʻoihana lāʻau lapaʻau a me nā mea hana kemika ʻē aʻe, ka ipu kaomi, nā meaʻai.
•Pharmaceutical: centrifuge, reactor, etc.
•Nā meaʻai kanu: ipu soya, kuke waina, paʻakai, lako a me nā lole.
•No ka dilute sulfuric acid ikaika corrosive medium steel 904 l ua like.
