I-S355JR vs ASTM A36: Umehluko Obalulekile kanye Nendlela Yokukhetha Insimbi Efanele Yesakhiwo

1. Kuyini i-S355JR kanye ne-ASTM A36?

Insimbi ye-S355JR vs Insimbi ye-A36:

I-S355JR kanye ne-ASTM A36 yizinhlobo ezimbili ezithandwa kakhulu zensimbi yokwakha ezisetshenziswa kabanzi emhlabeni wonke ngezicelo zokwakha.

I-S355JR iyibanga le-EN 10025, kanti i-ASTM A36 iyibanga le-ASTM, okuyizindinganiso eziqashelwa kakhulu e-United States kanye nakwezinye izingxenye zomhlaba. Womabili la mabanga angatholakala ezisetshenzisweni zesakhiwo ezifanayo, kodwa ifilosofi ngemuva kokuklama, izidingo zokuhlola, kanye nokusebenza kwemishini kuhluke kakhulu.

2. Ukuqhathaniswa kwezakhiwo zemishini

Impahla S355JR (EN 10025) I-ASTM A36
Amandla Okukhiqiza Okuncane 355 MPa 250 MPa
Amandla Okudonsa 470–630 MPa 400–550 MPa
Ukuhlolwa Komthelela Kuyadingeka (JR: 20°C) Akuphoqelekile
Ukushibilika Kuhle kakhulu Kuhle

Umehluko omkhulu kakhuluamandla okukhiqiza.

Amandla okukhiqizaI-S355JR ingaphezulu ngo-40% kunamandla okukhiqiza e-ASTM A36 okusho ukuthi izingxenye zesakhiwo zingenziwa zibe lula noma ukuthi imithwalo ingandiswa..

3. Ukuqina Komthelela Nokuphepha Kwesakhiwo

I-S355JR ifaka ukuhlolwa komthelela we-Charpy okuphoqelekile (ibanga le-JR ku-+20°C), okunikeza ukusebenza kokuqina okubikezelwayo ngaphansi kwezimo zokulayisha eziguquguqukayo.
Akukho mfuneko yanoma yikuphi ukuhlolwa komthelela we-ASTM A36, ngaphandle kokuthi umthengi esho kanjalo ku-oda lokuthenga.
Okuzosetshenziselwa: imithwalo enamandla ukudlidliza ukushintshashintsha kwezinga lokushisa elimaphakathi Kusetshenziswa ezinhlelweni zokulayisha eziguquguqukayo.
I-S355JR ineziqiniseko ezengeziwe zokuthembeka.

4. Izicelo Ezijwayelekile

S355JR

  • Amabhuloho kanye nezindawo zokudlula ngaphezulu

  • Izakhiwo ezinde

  • Amapulatifomu ezimboni

  • Ozimele bemishini esindayo

I-ASTM A36

  • Izakhiwo eziphansi

  • Ukwenziwa okuvamile

  • Amapuleti ayisisekelo namabhuleki

  • Izakhiwo ezithwala imithwalo ezingabalulekile

5. Unganquma kanjani phakathi kwe-S355JR ne-A36?

I-S355JR ingcono uma:

Ukunciphisa isisindo sesakhiwo kubalulekile
Imingcele yokuphepha ingaba phezulu
Babengaphansi kwezindinganiso ze-EN kuphrojekthi

Khetha i-ASTM A36 uma:

Intengo ibaluleke kakhulu
Imithwalo ilula kakhulu
Yiba nemithetho ye-ASTM."

6. Amaphutha Avamile Okufanele Uwagweme

Uma sicabanga ukuthi i-S355JR kanye ne-A36 ziyizilinganiso eziqondile

Ukungazinaki izidingo zokuqina komthelela

Ukusebenzisa i-A36 ezakhiweni ezizwela ukukhathala

I-S355JR kanye ne-ASTM A36 zisebenza ngezinjongo ezifanayo, kodwa azikwazi ukushintshaniswa ngaphandle kokuhlolwa kobunjiniyela.
