Hwm Galvanized Angle Steel A36 Q195 Q235 Q345 Qhov ntau thiab tsawg

Dab tsi yog qhov siab tshaj plaws thickness rau Q235?
A: Kev lag luam muaj txog li 200mm; yield zog txo nrog thickness.
Puas yog Q235 sib nqus?
A: Yog (ferromagnetic, zoo li feem ntau carbon steels).
Lub thermal conductivity ntawm Q235 yog dab tsi?
A: ~ 50 W / (m·K) (chaw temp).
Dab tsi yog qhov coefficient ntawm thermal expansion ntawm Q235?
A: ~ 12 × 10⁻⁶ /℃(20-100 degree).
Vim li cas Q235 thiaj li siv dav?
A: Tus nqi qis, lub zog zoo, zoo heev weldability / formability, yooj yim machining, ntau cov khoom siv-zoo tagnrho rau cov qauv siv dav dav thiab tsis yog- daim ntawv thov tseem ceeb.
