How effective is HDG galvanizing on Q235?
Good. Low-carbon steel exhibits strong adhesion and excellent corrosion resistance when hot-dip galvanized.
Can Q235 be used for high-strength bolts?
No, its strength is insufficient. High-strength bolts use quenched and tempered steel such as 45#/40Cr.
What are the fatigue properties of Q235?
Generally suitable for static loads. For alternating/dynamic loads, Q355 is preferred.
What is the price range for Q235?
It falls within the lower price range of ordinary carbon steel, approximately 10%–15% cheaper than Q355.
What are the delivery conditions for Q235?
Hot-rolled/cold-rolled/pickled/annealed, usually delivered in hot-rolled black-skin condition.
