AISI 304: āhuatanga hangarau. kowiri tira

AISI 304 whakaritenga e taea kitea e koe i roto i te tuhinga, ko te tirohanga o nga momo matua o te whānau o steels kowiri. Ko tēnei rauemi - austenitic maitai ki te ihirangi waro tika iti. Ka familiarized ki te paerewa kāwanatanga, e kua whakamahia i roto i Russia, ka taea e matau koe e rite ki te tauira ki te atawhai i maitai kōeke 08H18N10.

he waikawa-ātete rauemi whakaahuatia, i roto i te tua, ko ia e taea ki te mau te rongo wā-poto ki pāmahana ki runga ki te 900 ^o C. Ko enei āhuatanga motuhake e kore nga mea anake ki e aro kia utua, ki tokomaha o ratou, ki te kia tangohia, whakaritea, a ka kia kōrero i raro nei.

āhuatanga hangarau

AISI 304 whakaritenga e me pānui i mua ki te hopu, kua he kiato i roto i te whānuitanga o 7.9 ki te 7,93 g / cm ^3. Kurut kaha ko 505 MPa, i te tukua te ahotea ko 215 MPa. Vickers pakeke ko 129, Knoop pakeke he 138. Ki te ko koe he kaiwhakamahi tūmataiti, kia utu koutou whakarongo ki te rite o te GOST taonga.

AISI 304 whakaritenga kia e te āwhina hanga e koe te whiriwhiri tika, kua he plasticity i te taumata o 70%. Ko te pono tenei, ki te ko te matotoru pereti 50 mm. Ko te uara tawhiti o elasticity o te rauemi pae i 193 ki te 200 GPA. Ko te uara tawhiti kutikuti ko 86 GPA. I te pāmahana rūma, te uruhanga autō ko te 1.008. ātete Electrical Ko te rohe 7.2e-005 Ohm-cm, i te mea pono mo te pāmahana o te 20 ° ^C. ke te ana tēnei tautuhinga ki te 1.16E-04, ki te ara ake te pāmahana ki te 650 ° ^C.

He maha kiritaki e hiahia wera atu motuhake, me te, i roto i tenei take, ko reira 0.5 kJ / (g · K). kia rite koe ake me te pāmahana rewa, rerekē te reira i roto i te whānuitanga i 1400 ki te 1455 ^C. Ko te kawe ia waiariki o te rauemi, ko te 16.2 W / (m · K).

Ko te tono taketake me ngā āhuatanga motuhake

AISI 304, āhuatanga o nei i te aroaro i runga ake e whakamahia i roto i te hanga o te ventilation me paowa, me te flues. rauemi pai mohiotia i roto i te hanga o te taputapu mo te rokiroki, whakaputa me te waka o te waina, pia, waiu, me te tahi atu inu me te matū. whakamahia Steel te i roto i te hanga o te taputapu mo te ahumahi kai, me te matū, me te ngä whakatutuki.

Ki te hanga e te reira ruma kai, me te kīhini, me te putorino mō ngā take rerekē. Ētahi atu kei rino, me nga mea timatanga pūtake o te hoahoanga. Rau AISI 304 - he rauemi e tohu ana i te kōeke taketake o te hapu o steels kowiri. roto kai atu Kr, tona hanganga kia kia i te iti rawa 18%. Ki te whakaute ki Ni, ko tona taimaha rōrahi 10%. ka mea te ihirangi taua o te o tuatahi kai ai te hanganga i runga i te mata o te apa waikura, homai ana e ia te rauemi he ātete ki ngā matū. Ko tēnei ōwehenga o te āhuatanga i roto i te hanganga hanga reira taea ki te faaohipa antiferromagnetically āhuatanga.

Mōhiohio i runga i te hanganga o

AISI 304 kowiri wahi whārangi maitai ngā, pera kua whakaahuatia ana i runga i Kr, i roto nei i roto i te hanganga e taea ngā i 18 ki te 20%. No runga C, ka tona ihirangi mōrahi ko 0.08%. kia roto Fe i te rauemi i roto i te nui o 66,345 ki te 74%, me te faatura Mn, ka ona titoa o te mōrahi o te 2%. Kei Ni i roto i te whārangi i 8 ki te 10.5%, me te whakaaro ki a P ko S, te rauemi i roto i roto i to ratou mōrahi 0,045-0,03%, aua.

Whakaahuatanga maitai

E whakaatuhia ana i roto i te tuhinga waitohu kitea tona horapa i te hanga o te whakarewa ka paiherea me motumotu, taputapu whare me wāhanga whare paipa. Ki te puka whakahua o te pepa, ka taea te whakarōpūtia te parahi ki rauemi wera-whakataka, me te matao-whakataka, rite whakaritea e te hangarau production. te kitenga o konganuku Flat te i roto i te puka o ngā rārangi, me te pepa. kia tukinotia te mata o te tukutuku i roto i te tukanga whakaputa ai i roto i te ara tetahi rite taea he hua te whiwhi e whai ake nei ngā rerekētanga o te mata:

• whakaata;
• oro;
• Matt.

I te hoko puta putorino kowiri, i hanga nei e o hiko-ara. E kore te te rauemi i raro ki te te waikura i roto i aua wahi i reira kino aunoa rapirapi ranei i hanga e. Ka taea te whakamahi ipu i hanga i tenei rino hoki waka me te rokiroki o ngā hua o te ahumahi matū, te ahumahi kai. I roto i te take tuatahi e korero tatou e pā ana ki ngā matū ngoikore.

kia whai i te parahi ngongo-āhua i te tapawhā, porohita tapawha ranei-wāhanga ripeka. I roto i te tikanga o te whakaputa i nga hua e taea e tui o electrofusion ranei. Ka taea te orohia te mata i roto i enei take, pania whakaata ranei. AISI 304 (GOST 08H18N10) Kei te whakamahia hoki te hanga o kaho mo huruhuru, kvass me te pia, me te taputapu mo te hanga, meangiti coils, rāpihi, taputapu miraka, oko cryogenic, evaporators, rihi.

Ko te āhuatanga o te parahi pipe AISI 304

Mai i te rauemi whakaahuatia i roto i te tuhinga hua ngongo kowiri, e kua te taua ngā rite te hunga whakaahuatia ana i runga. E whakamahia ana ēnei hua mō te whakapanga pipelines no te kōrero i roto i tenei take i whakapati pūmau, te waikura ātete, e kore e tomo ki tauhohe matū ki ētahi atu matū, me te whai i te kaha ki te hanga ano ki te pakaru.

Ēnei putorino i kahore deformations me kōtītiti, to ratou he paninga o chromium waikura, e whakarato ana ātete ki te taiao o waho. Ko te hua i kaha pai, tuku moni ratou ratou tino paiherea, i te nui rawa o te ngäwari me te ātete ki te pāmahana. E tonu te mau huru taketake katoa ara i roto i ngā āhuatanga o te pāmahana iti rawa. Kei te āhuatanga e te humarie roa-te ora, o te tāutanga, me te noho pai o te tāutanga enei hua.

Scope putorino kowiri

kitea putorino he kowiri tira tona horapa tata nga wahi katoa. He he ahua ātaahua, e taea ai tāpae i roto i tetahi taiao. Ka taea te whakamahi putorino he kowiri tira ki te hanga taiapa, kohukohu, me arawhata, ka paiherea me whakarewa motumotu, i konei ngā tapawhā me korere tapawha, me ngā hua ngā momo. E whakamahia taua putorino ki whakapanga te paipa o ngā wāhi nui, ka taea e ratou hei wahi o te pūnaha whakapau o tou waka, ka whakamahia i roto i te hanga o ngā wāhanga whakapau me tumera.

Whakaahuatanga Stainless Steel tuke

Tuke AISI 304 hoki e taea te kitea i runga i te mākete i teie mahana. Ka taea e whai ratou momo katoa o papa, e kua whakahuatia i runga ake i roto i te mata brashtovannaya whakamahia te rite te whakatinanatanga atu. kia tikanga, elongated ranei nga körere.
