** 1. Dab tsi yog Suav sib npaug ntawm A36 Hlau? **
Cov Suav sib npaug ntawm Astm A36 hlau yog ** Q235 ** (GB \/ T 700 tus qauv). Q235 muaj cov khoom siv zoo sib xws rau A36, txawm tias qhov sib txawv me me muaj nyob rau hauv cov tshuaj muaj tshuaj lom neeg (piv txwv li, Q235 muaj cov ntsiab lus roj carbon ntau dua). Nws yog dav siv rau cov qauv txheej txheem dav dav hauv Suav teb.
** 2. Dab tsi yog A36 qib sib npaug rau? **
ASTM A36 yog qhov sib npaug dav dav rau:
- ** Rau (Europe): S235jr ** (en 10025-2)
- ** ISO: FE360B ** (ISO 630)
- ** JIS (Nyiv): SS400 ** (JIS G3101)
- ** India: E250 ** (yog 2062)
Cov qhab nia sib phim A36 qhov tsawg kawg nkaus tau lees lub zog (250 MPA) thiab cov khoom siv tensile, tab sis cov tshuaj lom neeg muaj feem ntau yuav txawv.
** 3. Dab tsi yog astm 36 yeeb nkab sib npaug rau? **
ASTM I36 yeeb nkab tuaj yeem muab piv rau:
- ** EN 10210: S235JRH ** (Rau Cov Txheej Txheem Kub-Ua Txheej Txheem Hollow)
- ** JIS G3444: STK400 ** (rau cov kav hlau hlau)
Cov kev sib txig sib luag rau cov yeeb nkab kaw cov ntawv thov nrog lub zog zoo sib xws thiab muaj zog.
** 4. Dab tsi yog 26 cov khoom sib npaug rau? **
SA 36 (ASME Boiler Code version version ntawm A36) yog tshuaj lom thiab siv mechanically zoo tib yam rau ASTM A36. Yog li, nws cov sib npaug yog qhov zoo ib yam: ** Q235 (Suav teb), S235JR (Europe), SF400 (JAPAN) **, thiab lwm yam.
** 5. Dab tsi yog A36 Khoom Siv? **
ASTM A36 yog EQUES-cov hlau muaj roj sib xyaw ua lub zog muaj zog ntawm 25pa (36 ksi) thiab tensile lub zog ntawm 400-550 mpa. Nws muaj cov pa roj (tsawg dua los yog sib npaug rau 0.26%), manganese, phosphorus, leej faj, thiab silicon. Dav siv dav siv hauv kev tsim kho, txuas hniav, thiab tshuab ua rau nws cov weldability, ductility, thiab nqi-ua hauj lwm zoo.
