I-ASTM A283 vs ASTM A709: Umahluko oPhambili kwiMifanekiso yeeKhemikhali, iiPropati zeMechanical, kunye neZicelo

Njengoko utyalo-mali lweziseko zophuhliso lwehlabathi luqhubeka lusanda, abakhi, abenzi bentsimbi, kunye namaqela okuthenga banikela ingqalelo ngakumbi kumahluko osebenzayo phakathi kwemigangatho eyahlukeneyo yentsimbi yokwakha.I-ASTM A283kwayeI-ASTM A709yimigangatho emibini yepleyiti yentsimbi esetyenziswa rhoqo, nganye ineempawu ezahlukileyo ngokwemilo yeekhemikhali, iimpawu zoomatshini, kunye nokusetyenziswa. Eli nqaku libonelela ngothelekiso olunzulu lweengcali zokwakha iibhulorho, izakhiwo zokwakha, kunye neeprojekthi zoshishino.

I-ASTM A283: Intsimbi yoLwakhiwo lweCarbon eSebenza ngexabiso eliphantsi

I-ASTM A283yipleyiti yesinyithi yesakhiwo sekhabhoni esetyenziswa kakhulu kwiiprojekthi zokwakha nobunjineli ngokubanzi. Iingenelo zayo ziquka:

Iyabiza kwaye ingabizi kakhulu

Ukudityaniswa kakuhle kunye nokusebenza kakuhle

Ifanelekile kwizicelo zesakhiwo eziqinileyo kancinci

Amanqaku aqhelekileyo aquka i-A283 Grade A, B, C, kunye no-D, kunyeIbanga CEyona isetyenziswa rhoqo. Iinkqubo eziqhelekileyo ziquka iitanki zokugcina izinto, izinto zokwakha ezilula, iipleyiti zokwakha eziqhelekileyo, kunye neendawo zobunjineli ezingabalulekanga.

Ngokuphathelele ukwakheka kweekhemikhali, i-A283 yintsimbi ekhabhoni ephantsi enezinto ezilula kwaye ayinayo i-alloying eyongezelelweyo, nto leyo eyenza ukuba ingabizi kakhulu kodwa ingabi namandla kwaye ihlale ixesha elide.

I-ASTM A709: Intsimbi enamandla kakhulu yeBhulorho

Ngokwahlukileyo koko, i-ASTM A709 yi-umgangatho wesinyithi wesakhiwo owenzelwe ngokukodwa ukwakhiwa kwebhulorho, esetyenziswa kakhulu kwiibhulorho zeendlela ezinkulu nezezitimela, kuquka imiqadi ephambili, imiqadi enqamlezileyo, iipleyiti zedekhi, kunye nezakhiwo ze-truss.

Amanqaku aqhelekileyo aquka:

Ibanga lama-36 le-A709

Ibanga lama-50 le-A709

I-A709 Grade 50W (intsimbi yokulungisa imozulu)

I-HPS 50W / I-HPS 70W (intsimbi esebenza kakhulu)

Iingenelo eziphambili ze-A709 ziquka:

Amandla aphezulu okuvelisa (≥345 MPa kwiBanga lama-50)

Ukuqina okugqwesileyo kobushushu obuphantsi kokudinwa kunye nokumelana nempembelelo

Ukumelana nokutshintsha kwemozulu okunokuzikhethela ukunciphisa iindleko zokugcina ixesha elide

Le ntsimbi inamandla okwenza i-A709 ilungele iibhulorho ezinde, izakhiwo ezinzima, kunye neeprojekthi ezifuna ukuqina ngokuchasene nokugqwala komoya.

Uthelekiso lweePropati zoMatshini

Ipropati I-ASTM A283 Ibanga C I-ASTM A709 Ibanga lama-50
Unikeze Amandla ≥ 205 MPa ≥ 345 MPa
Tensile strength 380–515 MPa 450–620 MPa
Ukuqina Kwempembelelo Iphakathi Igqibelele kakhulu (ifanelekile kwiibhulorho)
Ukumelana nemozulu Umgangatho Amanqanaba emozulu angama-50W/HPS

I-A709 ngokucacileyo inika amandla aphezulu, ukuqina, kunye nokuqina, okwenza ifaneleke ngakumbi kwizicelo zesakhiwo ezithwala umthwalo omkhulu kunye nezibalulekileyo.

Iingqwalasela zeendleko

Ngenxa yezinto ezongezelelweyo zokudibanisa kunye neemfuno eziphezulu zokusebenza,I-A709 ibiza kakhulu kune-A283 ngokubanzi. Kwiiprojekthi ezijongana nohlahlo-lwabiwo mali olunemfuno ephantsi yesakhiwo, i-A283 ibonelela ngokonga iindleko okungcono. Nangona kunjalo, ekwakheni iibhulorho kunye nezakhiwo ezinomthwalo omninzi, i-A709 yeyona nto ikhethwayo okanye egunyazisiweyo.

 

Iingcali zobunjineli zigxininisa ekukhetheni uhlobo olufanelekileyo lwentsimbi ngokusekelwe kwiimfuno zesakhiwo kuneendleko zodwa.

Iiprojekthi ezinomthwalo omncinci, ezingabalulekanga: I-A283 yanele.

Iibhulorho, izakhiwo ezihlala ixesha elide, imithwalo enzima yokudinwa, okanye ukuvezwa kwiindawo ezinzima: I-A709 iyimfuneko.

Njengoko uphuhliso lweziseko zophuhliso lwehlabathi lukhawuleza, imfuno ye-ASTM A709 iyaqhubeka nokukhula, ngelixa i-A283 ihlala izinzile kwiimarike zokwakha kunye nokwakhiwa kweetanki.
