ASTM-SA516Gr60Z35 pereti maitai te kitenga hapa:
1. SA516Gr60 paerewa whakahaere: American ASTM, ASME paerewa
2. SA516Gr60 no ki te iti pāmahana oko pēhanga ki te pereti waro maitai
3. Hanga matū o SA516Gr60
C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45.
4. Nga ahuatanga miihini o SA516Gr60
SA516Gr60 kaha tensile o 70 mano pauna / tapawha inihi, te ihirangi huānga matua ko C Mn Si ps mana whakatau tona mahi.He iti ake nga waahanga tohu.Asme Paerewa Whakatakotoranga mo nga pereti waro waro mo nga oko pehanga reo me te iti o te pāmahana.
5. Te mana tuku o SA516Gr60
Ko te pereti maitai SA516Gr60 te nuinga o te wa e tukuna ana i roto i te ahua okeoke, ka taea hoki te whakatikatika i te pereti rino, te whakamaarama ranei i te ahotea, te whakarite ranei me te ota whakaora ahotea.
SA516Gr60 matotoru> 40mm pereti maitai me whakarite.
Ki te kore e tohuhia e te kai tono, ko te matotoru o te pereti rino ≤1.5in, (40mm), ina he whakaritenga uaua kakari, me whakarite.
6. Kei te whakamahia te SA516Gr60 ki te hanga i te ipu kotahi-papanga porowhita fehokowhiowhio, maha-apa-apa-a-raupapa-a-ringa-a-ringa-a-ringa-a-ringa, ipu whakakakahu-maha me etahi atu momo ipu e rua me te toru me nga oko pehanga iti-mahana.Ka whakamahia nuitia i roto i te hinu, te ahumahi matū, te teihana hiko, te kohua me etahi atu mahi, whakamahia i roto i te hanga o nga reactors, whakawhiti wera, wehewehe, taika porowhita, taika hinu me te hau, taika hau liquefied, pahū pahū, liquefied petroleum steam cylinders, hydropower teihana. paipa wai pehanga teitei, puia turbine me etahi atu taputapu me nga waahanga.;
7. Kia ata whakamataohia te austenite (he rite ki te whakamahana o te oumu, penei i te Whakaahua 2 V1), ka tata nga hua panoni ki te hanganga taurite, ara te pearlite me te ferrite.Na te pikinga o te reiti whakamahana, ara, ina V3>V2>V1, ka piki haere te whakamahana o te austenite, ka iti haere te nui o te ferrite kua heke, ka piki haere te nui o te pearlite, ka pai ake te hanga.I tenei wa, ka tohatohahia te nuinga o te ferrite iti ki runga i te rohe o te witi.
8. Na reira, ko te hanganga o te v1 he ferrite+pearlite;Ko te hanganga o te v2 he ferrite+sorbite;Ko te hanganga moroiti o v3 he ferrite+troostite.
9. Ina he v4 te reiti whakamahana, he iti te ferrite whatunga me te troostite (i etahi wa ka kitea he iti o te bainite), ka huri te austenite ki te martensite me te troostite;Ka nui ake te reiti whakamahana v5 i te reiti whakamahana tino nui, ka huri katoa te maitai ki te martensite.
10. Ko te huringa o te maitai hypereutectoid he rite ki to te rino hypoeutectoid, me te rerekee ko te ferrite e tohe tuatahi ana ki to muri me te cimentite ka tohe tuatahi ki mua.
