What is Q235 steel plate?
Q235 is a common low-carbon structural steel plate in China, with low carbon content, good plasticity, toughness and weldability, widely used in general engineering and structural parts.
2. What does Q235 mean?
"Q" stands for yield strength, "235" means the minimum yield strength is 235MPa under normal temperature.
3. What is the chemical composition of Q235 steel plate?
Main elements: Carbon (≤0.22%), Silicon, Manganese, low Phosphorus and Sulfur; low carbon content ensures good processing performance.
4. What are the grades of Q235 steel?
Main grades: Q235A, Q235B, Q235C, Q235D; different in sulfur, phosphorus content and impact resistance.
5. What is the difference between Q235A and Q235B?
Q235A has no impact test; Q235B has room-temperature impact test, better toughness, suitable for outdoor and dynamic load parts.
