S355 iyo Q355 labaduba waa calaamado loogu talagalay birta qaab dhismeedka, laakiin waxay ka yimaadeen heerar kala duwan waxayna leeyihiin xoogaa kala duwanaansho ah tilmaamahooda iyo codsiyadooda.
S355 Birta
Heerka: EN 10025-2 (Heerka Yurub)
Darajada: S355
Sharaxaad: S355 waa bir qaabdhismeed aad u sarreeya, daawaha hoose leh oo leh awoodda wax-soosaarka ugu yar ee 355 MPa. Waxaa caadi ahaan loo isticmaalaa dhismaha iyo codsiyada qaabdhismeedka ay sabab u tahay alxanka wanaagsan iyo machinability.
Hoosaadyada Guud:
S355JR: Guud ahaan birta qaab dhismeedka leh ugu yaraan xoog wax soo saar oo ah 355 MPa iyo saamaynta tamarta 27J heerkulka qolka.
S355J0: Tamarta saamaynta ugu yar ee 27J at 0°C.
S355J2: Tamarta saamaynta ugu yar ee 27J at -20°C.
Q355 Birta
Heerka: GB/T 1591 (Heerka Shiinaha)
Fasalka: Q355
Sharaxaad: Q355 waa bir qaabdhismeed aad u saraysa oo leh awoodda waxsoosaarka ugu yar ee 355 MPa, oo la mid ah S355. "Q" waxay u taagan tahay "Qu" (dhibcaha wax-soo-saarka), iyo "355" waxaa loola jeedaa awoodda wax-soo-saarka ugu yar ee MPa.
Hoosaadyada Guud:
Q355B: Tamarta saamaynta ugu yar ee 27J at 20°C.
Q355C: Tamarta saamaynta ugu yar ee 27J at 0°C.
Q355D: Tamarta saamaynta ugu yar ee 27J at -20°C.
