Alloy N155 (R30155) Pepa, Papa
Nā inoa kālepa maʻamau: Alloy N155, Multimet N155, R30155, W.Nr 1.4974
ʻO Alloy N155 kahi huila Nickel-Chromium-Cobalt me nā mea hoʻohui o Molybdenum a me Tungsten i hoʻohana maʻamau i nā ʻāpana e koi ana i ka ikaika kiʻekiʻe a hiki i 1350 ° F a me ke kūpaʻa oxidation a hiki i 1800 ° F.ʻO kona mau mea wela kiʻekiʻe i loko o ke kūlana i hoʻolako ʻia (ka hopena i mālama ʻia ma 2150 ° F) a ʻaʻole hilinaʻi i ka paʻakikī makahiki.Hoʻohana ʻia ʻo Multimet N155 i ka nui o nā noi aerospace e like me nā tailpipes a me nā cones huelo, nā lau turbine, nā shafts a me nā rotors, nā ʻāpana afterburner a me nā bolts wela kiʻekiʻe.

ʻO Alloy N155 nā huahana i loaʻa ma Sekonic Metals
Alloy N155 kaola a me na kookoo
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
Alloy N155 welding wire & Spring wire
Hoʻolako ʻia ma ka uea kuʻi a me ka uea puna ma ke ʻano coil a ʻoki ʻia ka lōʻihi.
Alloy N155 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 N155 apo apo
Forging Ring a i ʻole gasket, hiki ke hoʻopili ʻia ka nui me ka ʻālohilohi a me ka hoʻomanawanui pololei
Alloy N155 strip & coil
ʻO ke kūlana palupalu a me ke kūlana paʻakikī me ka ʻili ʻālohilohi AB, ka laulā a hiki i 1000mm
No ke aha ʻo Alloy N155?
Loaʻa i ka Alloy N155 ke kūpaʻa maikaʻi i ka corrosion i kekahi mau media ma lalo o nā kūlana oxidizing a hoʻemi.Ke mālama ʻia ka wela, ua like ke kūpaʻa ʻana o ka alloy N155 i ka waikawa nitric me ke kila kila.ʻOi aku ka maikaʻi o ke kūpaʻa ma mua o ke kila kila i nā hopena nāwaliwali o ka waika hydrochloric.Kūʻē ʻo ia i nā konohiki a pau o ka sulfuric acid ma ka lumi wela.Hiki ke hoʻopili ʻia ka alloy, hana ʻia a hana ʻia e nā ʻano hana maʻamau.
Hiki ke hoʻopili ʻia ka alloy e nā ʻano arc a me nā kaʻina hana pale-weld.Loaʻa kēia alloy ma ke ʻano he pepa, strip, plate, wire, coated electrodes, billet stock and sane and investment castings.
Loaʻa iā ia ma ke ʻano o ka hoʻoheheʻe hou ʻana i kahi kemika i hōʻoia ʻia.Hoʻouna ʻia ka hapa nui o nā ʻano huila n155 i ka hopena i mālama ʻia i ka wela e hōʻoia i nā waiwai kūpono.Hāʻawi ʻia ka lau i kahi hoʻoponopono wela o 2150°F, no ka manawa e pili ana i ka mānoanoa o ka ʻāpana, a ukali ʻia e ka ea wikiwiki a i ʻole ke kinai wai.ʻO ka pahu pahu a me ka pā (1/4 in. a ʻoi aku ke kaumaha) ʻo ia ka hopena wela i mālama ʻia ma 2150°F a ukali ʻia e ke kinai wai.
Ua pilikia ʻo Alloy N155 mai ka mediocre oxidation resistance, kahi ʻano no ka wela o ka wahi i hoʻopili ʻia i ka wā wili, a me kahi puʻupuʻu ākea ākea o nā waiwai mechanical.
