TusS3555j2wp huab cua dav hlaufeem ntau xa hauv cov xeev hauv qab no, nyob ntawm cov qauv tsim khoom (piv txwv li,EN 10025-5) thiab cov ntawv thov yuav tsum muaj:
1. Kub Rolled (Hr)
Kev ua: Dov ntawm qhov kub siab (≈900 degree), tom qab ntawd huab cua txias.
Cov Khoom Siv:
Tus qauv xa cov ntsiab lus rau feem ntau cov ntawv thov.
Formability zoo thiab weldability.
Rust-resistant tab sis tej zaum yuav xav tau huab cua huab cua kom ruaj khov rau cov patina.
Raug Siv Siv: Txuas hniav, tsev facades, tsis yog tus txheej txheem tseem ceeb.
2. Qub (n)
Kev ua: Kub-rolled steel yog rov ua kom ≈900℃thiab txias rau hauv tseem huab cua rau cov khoom siv microstructure.
Cov Khoom Siv:
Txhim kho kev nruj thiab kev kho tshuab cov tshuab vs. kub-dov.
Zoo dua Weldability thiab cuam tshuam tsis kam ntawm tsawg kub.
Raug Siv Siv: Hnyav-Thauj Cov Txuas hniav Ua Si, Offshore Cov Qauv, lossis huab cua hnyav.
3. Thermomechanical tswj dov (tmcr lossis CR)
Kev ua: Dhuav cov dov ntawm kev tswj hwm kub (hauv qab no recrystallization) ua raws los ntawm kev txias kom nrawm.
Cov Khoom Siv:
Lub zog siab dua thiab cov qauv zoo dua li kub-dov.
Kev muaj kuab heev thiab corrosion tsis kam.
Tsis muaj kev kho cua sov ntxiv.
Raug Siv Siv: High-horrium Cheebtsam (piv txwv li, crane ntsia, seismic-resistant qauv).
