What is Q235COIL?
Q235COIL is a coiled steel product made from Q235 ordinary carbon structural steel through hot rolling/cold rolling. "235" represents a yield strength ≥ 235 MPa.
What does the Q235 designation mean?
"Q" refers to yield strength, "235" is the yield strength value (MPa), and A/B/C/D are quality grades, distinguishing impact performance and impurity content.
What is the difference between Q235COIL and Q235 steel plate?
COIL is a coiled intermediate product that needs to be leveled and sheared before use; steel plate is a pre-processed, flat plate that can be directly cut.
What type of steel is Q235COIL?
It belongs to low-carbon carbon structural steel, with a carbon content of approximately 0.14%-0.22%, and contains no special alloying elements.
What are the quality grades of Q235COIL?
It is mainly divided into Q235A, Q235B, Q235C, and Q235D. Class B has room temperature impact resistance, Class C has 0℃ impact resistance, Class D has -20℃ impact resistance, and Class A has no impact requirements.
