I-AISI vs. ASTM: Ukuqonda iMigangatho yeeMbhobho zeNtsimbi engaGciniyo

Intshayelelo

Iilebheli ezifana ne-AISI 316 kunye ne-ASTM A312 zihlala zibonakala kunye kwiishethi ze-spec, kodwa azifani. Ukukhetha engalunganga kunokukhokelela ekulibazisekeni kweprojekthi okanye ekusileleni kwepayipi. Esi sikhokelo sichaza umahluko phakathi kwe-AISI kunye ne-ASTM ukunceda ishishini lakho lifumane ipayipi yentsimbi engagqwaliyo ye-ASTM efanelekileyo ngalo lonke ixesha.

Yintoni i-ASTM

Ukuba uthengisa isinyithi, uzibonile ezi nobumba zine kuyo yonke indawo. Kodwa zithetha ukuthini ngokwenene kwixabiso lakho?

Ifomu epheleleyo ye-ASTM

Ifomu epheleleyo ye-ASTM imele i-American Society for Testing and Materials. Bacinge njengabagwebi behlabathi jikelele bomgangatho wemizi-mveliso. Abakhathaleli nje kuphela oko kungaphakathi kwesinyithi; bakhathalele indlela esebenza ngayo loo sinyithi xa usibeka phantsi koxinzelelo kumzi-mveliso.

Indima ye-ASTM kwiMibhobho

Kwihlabathi le-astm standard yepayipi yentsimbi engagqwaliyo, le ntlangano ibeka imithetho yomdlalo. I-ASTM standard ikuxelela ngqo indlela ekufuneka yenziwe ngayo ipayipi, ukuba kufuneka iindonga zibe nkulu kangakanani, kunye nokuba ingakanani uxinzelelo enokuluthatha ngaphambi kokuba iqhume. Ngaphandle kwale mithetho, ukuthenga iipayipi kwamanye amazwe bekuya kuba yinto enzima kakhulu.

I-AISI vs. ASTM: Yintoni umahluko ophambili

Kulapho ke uninzi lwabaphathi bokuthenga lukhubeka khona. Umahluko phakathi kwe-AISI kunye ne-ASTM ulula xa uwujonga ngendlela esebenzayo:

I-AISI yiResiphi: I-American Iron and Steel Institute igxile kwizithako. Ukuba ufuna intsimbi enomlinganiselo othile weChromium okanye iNickel, i-AISI ikuxelela ngekhemistri.

I-ASTM yiBlueprint: I-ASTM ithatha loo resiphi ize yongeze imiyalelo. Igubungela ukwenziwa kwetyhubhu yesinyithi, unyango lobushushu, kunye novavanyo loxinzelelo.

Ikhemistri vs. UkusebenzaI-AISI ithi intsimbi yi-304; i-ASTM ithi intsimbi eyi-304 ivavanyiwe kwaye ikhuselekile ukuyisebenzisa njengombhobho wentsimbi engagqwaliyo ye-ASTM enoxinzelelo oluphezulu.

Utshintsho kwiGunyaNamhlanje, i-AISI irhoxe kakhulu ekubhaleni imigangatho emitsha. Phantse zonke iinkcukacha zobunjineli zanamhlanje ngoku zixhomekeke kwinkqubo ye-astm yentsimbi engagqwaliyo ukuze kucace okusemthethweni nobuchwepheshe.

I-AISI 304 vs. ASTM 304: Ngaba Ziyinto Efanayo?

Usenokuva umntu esithi, Ndifuna ipayipi ye-AISI 304. Kwincoko eqhelekileyo, abantu bayazi ukuba uthetha ukuthini. Kodwa kwisivumelwano esisemthethweni, kukho umsantsa omkhulu phakathi kwe-aisi 304 ne-astm 304.

Ibanga lezinto: I-AISI 304 ibhekisa kuphela kudidi lweekhemikhali. Ikuxelela ukuba isinyithi siqulethe malunga ne-18% Chromium kunye ne-8% Nickel.

Inyani yeMveliso: I-ASTM 304 zizinto ezisetyenziswa ngaphakathi komgangatho othile wemveliso, njenge-ASTM A312.

Kutheni Ungenakukwazi Uku-odola i-AISIUkuba uodola ngegama le-AISI kuphela, awuchazi ukuba umbhobho kufuneka ungabi namthungo okanye udityaniswe, okanye ukuba kufuneka uvavanywe ngamanzi.

Umsantsa Wokhuseleko: Umbhobho we-ASTM stainless steel uqinisekisiwe ukuba uyahlangabezana neemfuno zomzimba. Iqhekeza lesinyithi elihlangabezana kuphela ne-AISI 304 chemistry lisenokuba neentanda zangaphakathi okanye iindonga ezingalinganiyo ezenza kube yingozi ekuthuthweni kolwelo.

I-AISI 316 vs. ASTM 316: Yeyiphi Efanele Isetyenziswe Yishishini Lakho

Xa iprojekthi yakho ibandakanya amanzi anetyuwa okanye iikhemikhali ezirhabaxa, ingxoxo ye-aisi 316 vs astm 316 iba yinto yokusinda kwizixhobo zakho.

Umgangatho woLwandle: I-AISI 316 idume ngomxholo wayo weMolybdenum, othintela ityuwa ekutyibeni imingxunya kwisinyithi.

Inkcazo yoBunjineliIinjineli zikhetha i-ASTM 316 kuba iza neNgxelo yoVavanyo lweMill (MTR). Eli phepha lingqina ukuba umbhobho udlule kwimigangatho ye-ASTM yeenkqubo zovavanyo lombhobho wentsimbi engagqwaliyo.

IMatrix yeSigqiboSebenzisa amanani e-AISI xa uthetha neqela lakho malunga neentlobo zezinto eziphathekayo. Sebenzisa amanani e-ASTM xa uthumela i-Purchase Order kumthengisi weetyhubhu zentsimbi engagqwaliyo eTshayina.

UkutshintshiselanaKwiimeko ezininzi, umbhobho ohlangabezana ne-ASTM A312 Grade TP316 uyahlangabezana ngokuzenzekelayo neemfuno ze-AISI 316, kodwa okuchaseneyo akusoloko kuyinyaniso.

Izizathu ezi-5 eziphambili zokuba kutheni iMigangatho ye-ASTM ibalulekile kwiipayipi zentsimbi engagqwaliyo

Kutheni uzikhathaza ngalo lonke eli phepha? Kuba umgangatho we-astm wepayipi yentsimbi engagqwaliyo ukhusela ishishini lakho kwiimpazamo ezibizayo.

Ukhuseleko loxinzelelo: Imibhobho ye-ASTM ivavanywa ngamanzi. Oku kuqinisekisa ukuba umbhobho awuyi kusilela xa oomatshini bakho besebenza ngokuthambekela ngokupheleleyo.

Ukumelana nokugqwalaImigangatho efana ne-ASTM A312 ifuna ukuqhoboshelwa ngokufanelekileyo (unyango lobushushu). Oku "kubuyisela" ulwakhiwo lwesinyithi ukuze sikwazi ukulwa nomhlwa ngempumelelo.

Ukungaguquguquki koBumeUkuba usebenzisa ukwenziwa kweetyhubhu zesinyithi ezenzekelayo, kufuneka umbhobho ube ngqukuva ngokugqibeleleyo. I-ASTM imisela ukunyamezelana okungqongqo kobubanzi kunye nobukhulu bodonga.

Ukulandeleka: Yonke ipayipi ye-ASTM iqhagamshelwe kwinani lobushushu. Ukuba kukho into engahambanga kakuhle, ungalandela isinyithi ubuyele kwibhetshi kunye nomatshini wokugaya ngqo.

Ukuthobela imithetho kwihlabathi liphelaNokuba useYurophu, eMelika, okanye eAsia, i-stainless steel astm lulwimi olusetyenziswa ngabantu bonke olugcina wonke umntu ekwiphepha elinye.

Indlela Yokufumana ngokuchanekileyo Imibhobho ye-ASTM yeNtsimbi Engagqwaliyo evela eTshayina

Ukufumana ulwazi kwi umthengisi wetyhubhu yentsimbi engagqwali yaseTshayina yindlela entle yokonga iindleko, kodwa kufuneka uchaze ngokuthe ngqo.

Musa Ukuthi Nje 304L: Cacisa. Cela i-ASTM A312 TP304L ukuze ifakelwe imibhobho ngokubanzi okanye I-ASTM A554 ukusetyenziswa kokuhombisa okanye koomatshini.

Qinisekisa iStencil: Inyani umbhobho wentsimbi engagqwali ye-astm iya kuba nomgangatho, Uhlobo lwentsimbi engatyiwayo, kunye nenombolo yobushushu eprintwe ngqo kumphezulu wombhobho.

Jonga iSatifikethi seMill: Ngaphambi kokuba uthumele, cela i-MTR. Qinisekisa ukuba amanqanaba eekhemikhali ayahambelana neemfuno ze-AISI kwaye uvavanyo loomatshini luyahlangabezana nemithetho ye-ASTM.

Qonda UmahlukoQinisekisa ukuba umthengisi wakho uyazi umahluko phakathi kwe-aisi kunye ne-astm. Ababoneleli abaziingcali baya kuhlala bekhokela ngeenkcukacha ze-ASTM.
