INCONEL® huila 690(UNS N06690/W. Nr. 2.4642) he kiʻekiʻe-chromium nickel alloy me ke kūpaʻa maikaʻi loa i ka nui o nā media aqueous corrosive a me nā lewa wela kiʻekiʻe.Ma waho aʻe o kona pale ʻana i ka corrosion, ʻo ka alloy 690 ka ikaika kiʻekiʻe, ke kūpaʻa metallurgical maikaʻi, a me nā ʻano hana hana maikaʻi.
Hāʻawi ka Inconel Alloy 690 Pipe & Tube i ke kūpaʻa kiʻekiʻe i ka laulā o nā media corrosive e like me ka chloride ion stress cracking a me ka hāʻawi ʻana i ka hana wela kiʻekiʻe a kumu ke kū'ē i ka oxidation.
ʻO ka Inconel Alloy 690 Pipe & Tube he austenite nickel-chromium-based superalloys grade tube, tubing, pipe & tubular products to Oil and Gas, Nuclear and Power, Power Generation, Aerospace, Process Industries & Refining, General Industrial, Chemical Process, Medical , Hoʻomaʻemaʻe kiʻekiʻe a me ka hana kiʻekiʻe.Ua kūpono ʻo Inconel Alloy 690 Pipe & Tube no ka lawelawe ʻana ma nā wahi koʻikoʻi i lalo i ke kaomi a me ka wela.

ʻO ka hoʻomehana a me ka Pickling
E like me nā huila nickel ʻē aʻe, pono e hoʻomaʻemaʻe ʻia ka alloy 690 ma mua o ka hoʻomehana ʻia a pono e hoʻomehana ʻia i loko o kahi ea haʻahaʻa-sulfur.Pono e hoemi iki na ea o ka umu ahi no ka hoomaha ana i mea e pale ai i ka oxidation nui o ka mea.
ʻO INCONEL alloy 690 kahi huila paʻa paʻa a ʻaʻole hiki ke paʻakikī e ka mālama wela.Hoʻohana mau ʻia ka mea hao ma ke kūlana annealed.
Hoʻokumu
ʻO ka pae wela no ka hana wela nui o INCONEL alloy 690 he 1900 a 2250 ° F (1040 a 1230 ° C).Hiki ke hana ʻia ka māmā ma nā mahana a hiki i 1600°F (870°C).
Microstructure
ʻO INCONEL alloy 690 he austenitic, solid-solution alloy me kahi kiʻekiʻe o ke kūpaʻa metallurgical.He haʻahaʻa ka hoʻoheheʻe ʻana o ka alloy no ke kalapona, a ʻo kona microstructure ka mea maʻamau i loko o ka carbide.ʻO ka carbide nui i loaʻa i loko o ka huila M23C6;ʻokoʻa ka nui o ka māhele me ka maʻi kalapona a me ka ʻike wela o ka mea.ʻO nā ʻāpana ʻē aʻe i loaʻa maʻamau he titanium nitrides a me carbonitrides.ʻAʻole i ʻike ʻia nā ʻāpana intermetallic embrittling e like me ka pae sigma ma ka alloy 690.
