Q: What is the density of Q235 steel plate?
A: The density is approximately 7.85 g/cm³, consistent with ordinary steel.
Q: What is the thermal conductivity of Q235 steel plate?
A: The thermal conductivity at room temperature is approximately 48 W/(m·K), suitable for components requiring heat transfer.
Q: What is the melting point range of Q235 steel plate?
A: The melting point is approximately 1430~1500℃, similar to that of ordinary carbon steel.
Q: What is the corresponding European standard grade for Q235 steel plate?
A: It approximately corresponds to European standard S235JR. Their mechanical properties are similar, but their chemical composition and testing standards differ slightly.
Q: What is the corresponding American standard grade for Q235 steel plate?
A: It approximately corresponds to American standard A36. A36 also has a yield strength of around 250 MPa (close to Q235) and is commonly used in construction and structural components.
