Nā mea waiwai

Nui nā waiwai maikaʻi i loaʻa i loko o ka huahana hoʻokahi no ka maikaʻi o ka hana ʻana o ka pepa. ʻO kēia ka ikaika tensile kiʻekiʻe, ka pololei dimensional maikaʻi, ka hoʻopau ʻana i ka ʻili, ka maʻalahi a me ka paʻa, kū i nā ukana kaumaha, ke kūkulu ikaika a me ke kūpaʻa ʻana i ka corrosion. ʻO ke kū'ēʻana i kaʻinoʻino, ke koʻikoʻi kaʻinoʻinoʻino, ka'ōpalaʻinoʻino, ka oxidation\/pitting corrosion kūpono ia no nāʻano noi.

Hoʻomaʻamaʻa ʻia nā ʻāpana kila chrome molybdenum a pau e like me ka ASTM A387, e kuhikuhi pū ana i nā pae liʻiliʻi a me nā pae kiʻekiʻe o kēia mau mea i ke kila: Kemika o Carbon, Manganese, Phosphorus, Sulfur, Silicon, Chromium, Molybdenum, Nickel, Vanadium koi, columbium, boron, nitrogen, aluminika, titanium. Pono nā papa A387 e hoʻāʻo i ka huahana, kemika a me ka tensile (i kākau ʻia ma ka MTC a i ʻole ka palapala hōʻike mea waiwai) - pono e hoʻokō i nā koi kikoʻī no ka ikaika tensile, ka ikaika a me ka elongation.

A\/SA387 GR 9CLASS 2 Weldable carbon steel plate no nā ipu kaomi wela kiʻekiʻe a me nā paila. Loaʻa ka waiwai mai ka chromium a me ka molybdenum i hoʻohui ʻia, ka mea e hāʻawi ai i ke kila ʻoi aku ka maikaʻi o ka corrosion a me ka pale wela. Hoʻohana ʻia ʻo A\/SA387 Grade 9 no ka hoʻohana ʻana e nā mea hana e lawelawe ana i ka ʻoihana aila, kinoea a me nā ʻoihana petrochemical.

ʻO ka papa 304 \/ 304L kila kila ka liʻiliʻi o 18% chromium a me 8% nickel. ʻO ka ʻokoʻa wale nō ma waena o lākou ʻo ka ʻike kalapona. Loaʻa i ka ʻano 304 ke kalapona kiʻekiʻe o 0.07% . ʻO ka type 304L ka nui o ke kalapona o 0.030 %. Hoʻopili kēia ʻano kalapona i loko o nā kila i ka pale ʻana i ka corrosion. Loaʻa ka 304 \/ 304L i ka pepa, ka ʻili pepa, ka pā, ka ʻili pā, ka pā pōʻai, ka pā paʻa i hana ʻia a me nā huahana tubular no ka hana hou ʻana.

ASTM\/ASME A387\/SA387 Alloy Steel Gr. 5 CL 1\/2 he chrome molybdenum alloy plate i hoʻohana mua ʻia i nā paila welded a me nā ipu kaomi i hoʻolālā ʻia no ka lawelawe wela kiʻekiʻe. ʻO ka maʻiʻo Cr he 5.00%, a ʻo ka maʻiʻo Mo he 0.5%.

ʻOi aku ka nui o ke kumukūʻai ʻoi aku ka maikaʻi o nā mea hao nui o nā kila super-austenitic. Hiki i nā kila ʻē aʻe ke hāʻawi i nā waiwai like me ke kumu kūʻai haʻahaʻa a makemake ʻia i kekahi mau noi. Hoʻohana ʻia nā mana kalapona haʻahaʻa, e like me 316L a i ʻole 304L, no ka pale ʻana i nā pilikia ʻino.

Hiki ke ho'opa'a 'ia ka ua i ka ikaika 'oi a'e ma mua o nā mākau martensitic 'ē a'e. Hoʻohana ka 17-4PH maʻamau ma kahi o 17% chromium a me 4% nickel. ʻO ka Lockheed-Martin Joint Strike Fighter ka mokulele mua i hoʻohana i ke kila kuhili hiki ke paʻakikī i ka ua ʻo Carpenter Custom 465 i loko o kāna fuselage.

Hoʻopili ʻia nā papa i nā kūlana like ʻole e hāʻawi iā lākou i ka ikaika. No ka mea e hana ʻia kēia mau papa i nā wela kiʻekiʻe a me ke kaiapuni puʻuwai no laila he mea nui nā mea i komo i loko. He aha nā mea i hoʻohui ʻia i ka hana ʻana e hoʻohui i nā waiwai like ʻole no ka laʻana, kiʻekiʻe kiʻekiʻe o ka chromium e hoʻohui i ke kūpaʻa corrosion maikaʻi loa. Hāʻawi pū ia i ka pale oxidation maikaʻi loa. He mea nui ka pale ʻana i ka oxygen i nā ʻoihana petrochemical a me ke kinoea a no laila hoʻohana ʻia kēia mau papa.

Loaʻa iā 304 nā waiwai mechanical maikaʻi loa a kūʻē i nā ʻano mea ʻino. ʻO 304\/304L nā ʻili kila kila a me nā pā he ʻāpana o ka ʻohana kila kuhili ʻole austenitic. He haʻahaʻa ko ka papa 304 ma mua o 302 a me 304\/304L he haʻahaʻa haʻahaʻa ka carbon ma mua o ka papa kuhikuhi 304. ʻO nā ʻano 304 a me 304L maikaʻi loa ka stretchability a me ke kūpaʻa maikaʻi ʻana i ka corrosion i nā kemika, textile, petroleum a me nā ʻoihana meaʻai.

He koho maikaʻi loa ʻo 304 Stainless Steel Sheet no nā mea kila kila maʻamau e like me ka lumi kuke a me nā noi hoʻoponopono meaʻai, ka waiho ʻana o ka wai a me nā pahu, nā mea hoʻololi wela, nā facades hale, nā moku kaomi a me nā noi ʻē aʻe e pili ana i nā kaiapuni wai hou. Hāʻawi mākou i kahi ākea ākea o Bright Annealed AISI 304 Sheet.

ʻO nā ʻano kila kila 1.4301 a me 1.4307 ka mea i ʻike ʻia he mau māka 304 a me 304L. 'O ke 'ano 304 ka kila kila maika'i loa a ho'ohana nui 'ia. Ua kapa ʻia ʻo ia i kekahi manawa e kona inoa kahiko 18\/8 i loaʻa mai ka haku inoa o ke ʻano 304 he 18% chromium a me 8% nickel.

A240 Type 304 ʻāpana ʻoki kila kila. ʻO ASTM a240 (Chromium a me Chromium Nickel Stainless Steel Sheet, Sheet and Strip for Pressure Vessels and General Applications. A240 304 Stainless Steel he mea maʻamau i loko o Stainless Steel me ka density o 7.93g \/cm3, i ʻike ʻia ʻo 18 \/8 Stainless Steel Industrial Hana ʻia i ke kila, hoʻohana nui ʻia a me ka ʻoihana meaʻai a me ka ʻoihana meaʻai.

Kūleʻa ka papa 304\/304L i ka ʻinoʻino o ka lewa, me ka hoʻohui ʻana i kahi kaiapuni oxidizing a hoʻemi kūpono. Loaʻa iā ia ke kūpaʻa maikaʻi loa i ka corrosion intergranular i ke kūlana as-welded. Loaʻa i ka ASTM A \/304L Dual Grade ka ikaika a me ka paʻakikī i nā haʻahaʻa haʻahaʻa. Ma hope o ka ʻōwili anu, hoʻoponopono ʻia i ka hoʻoponopono wela, pickling a i ʻole hoʻoponopono ʻē aʻe, a ma hope o ka ʻōwili anu e loaʻa ai ka ʻoluʻolu.

ʻO kā mākou laina piha o SMO UNS S32760 Plates e hāʻawi i ka helu o nā mea kemika koʻikoʻi a me nā hiʻohiʻona e like me ke kūpaʻa kiʻekiʻe, nā kūlana hoʻopau paʻa, Toughness etc.

Alloy 904L pā kila kila ma nā mānoanoa mai 3\/16″ a hiki i 2″. ʻO Alloy 904L (UNS N08904) he kila kila kila superaustenitic i hoʻolālā ʻia no ka corrosion a me ka pitting resistance i kahi ākea o nā kaʻina hana.

304 pā kila i hoʻoheheʻe ʻia i loko o nā wili, nā ʻāpana, nā pā, nā kaola, ka uea, a me nā paipu no ka hoʻohana ʻana i nā mea kuke, nā papa ʻaina, nā lako, nā mea ʻokiʻoki, nā mea hana nui, nā mea hana ʻoihana (e like me ka hoʻomaʻemaʻe kōpaʻa), a me nā hale kaʻa a me nā aerospace Nui nā Alloys a me nā mea kūkulu hale i nā hale.

ʻO 304\/304L ka pā kila kila kekahi o nā māka kuhili ʻole a hoʻohana nui ʻia. Ma muli o kona ʻano kalapona haʻahaʻa a me ka haku mele chromium kiʻekiʻe, ʻo kēia papa i waena o nā mea maikaʻi loa ma kāna papa no ka ikaika, ke kū ʻana i ka corrosion, a me ka formability.

Pono e hoʻokō ʻia nā kikoʻī hoʻohui kemika i ʻōlelo ʻia ma ka maʻamau e ke kila Super Duplex Plate. ʻO ka maʻiʻo, i kēia hihia Thick Duplex Alloy 2507 Cold Rolled Sheet, pono e hoʻokō i nā pono mechanical pono.

Hoʻohana nui ʻia ka papa 304L i ka ʻoihana hana a hiki ke hoʻohana ʻia nā ʻenehana wili maʻamau āpau no ka pā 304L a me ka paipu 304L. ʻO ka "L" ma 304L ke kū nei no "ka haʻahaʻa kalapona haʻahaʻa" a hōʻike i kahi maʻi kalapona kiʻekiʻe o 0.035%. ʻO ka "H" ma 304H ke kū nei no ka "High Carbon Content", ʻo ia hoʻi, ʻaʻole i emi iho ka waihona kalapona ma lalo o 0.04% a ʻaʻole i oi aku ma mua o 0.10%.

ʻO SS 304, SS 304L, SS 316 a me SS 316L nā ʻāpana kila kila maikaʻi loa a maikaʻi loa. ʻO ke kila kila 304\/304L ka pā a me ke kila kila 316\/316L ka pā a me ka duplex stainless steel plate i ka pale ʻana i ka corrosion maikaʻi i nā wahi kemika he nui a me nā hōʻike moana a me nā ʻoihana.

Hoʻopili ka ASTM A240 kikoʻī i ka chromium, chromium-nickel, a me ka chromium-manganese-nickel stainless steel plate, sheet, and strip no ka hoʻohana ʻana i nā moku kaomi a me nā noi maʻamau, e pili ana i ka hoʻolālā, hale kiʻi, hana, a me nā noi nani.

ʻO ke kila kila, ʻike ʻia hoʻi he kila inox, he kila kila me ka liʻiliʻi o 10.5 a i ʻole 11% chromium ma ka nuipa.

ʻAʻole hiki ke hoʻopaʻa, ʻino, a ʻeleʻele paha ke kila kila 2B-finish e like me ke kila maʻamau, akā ʻaʻole hiki ke pale ʻia.

Ke emi ka chromium ma lalo o 12%, no ka laʻana ma ka ʻoihana aerospace, hoʻohana ʻia ka huaʻōlelo "corrosion resistant steel". Hiki mai ke kila kila ma nā māka like ʻole a me ka hoʻopau ʻana o ka ʻili, ma muli o kahi i hoʻohana ʻia ai.

ʻO ka lawe ʻana i ka mea kūʻai ma ke kikowaena, ʻo kā mākou pahuhopu hope loa ʻo ka wili kila kila, ʻo TISCO kumu, nā aniani pā kila kila, 316LVM pahu kila kila. Hoʻoikaika mākou e hoʻokō i nā pono o nā mea kūʻai aku, e kau mau i ka makemake o nā mea kūʻai aku a me ka ulu ʻana o nā limahana ma kahi mua, a lawe i kahi ala hoʻomohala kūpono, kūpaʻa, olakino a hoʻomau.

ʻO ke kila kila he mea hao me ka liʻiliʻi o 10.5% chromium. Hoʻopuka ʻo Chromium i kahi ʻāpana lahilahi o ka oxide ma ka ʻili o ke kila, i kapa ʻia ʻo "passivation layer".

Loaʻa i ke kila kila ka nui o nā kalapona, silika a me manganese. Hiki ke hoʻohui ʻia nā mea ʻē aʻe, e like me ka nickel a me ka molybdenum e hāʻawi i nā waiwai pono ʻē aʻe e like me ka hoʻonui ʻana i ka formability a me ka hoʻoikaika ʻana i ka pale ʻana i ka corrosion.

Hiki ke kōkua ka ʻike ʻana i ka pau ʻana o kēia mau kila inā ʻike ʻia kāu mau paipu a aia nā hiʻohiʻona ma ka papa inoa o nā manaʻo. He ʻōlinolino maʻamau ke kila kila a hiki ke mālama i kēlā ʻōlinolino inā ʻike ʻia i ka wā a me nā mea ʻē aʻe. ʻO ke kila kalapona, ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka ʻeleʻele o ka waihoʻoluʻu a maʻamau ka hopena matte ke pena ʻia. ʻO ka mea pōʻino, hiki ke ʻōpala a nānā ʻino ke waiho ʻia. ʻO ka Galvanizing kekahi koho.
