What is Q195 steel coil?
Q195 steel coil is a low-carbon structural steel coil produced according to the Chinese national standard GB/T 700-2006. "Q" represents yield strength, and "195" indicates a yield strength ≥195MPa for thicknesses ≤16mm.
What is the standard for Q195?
It primarily complies with GB/T 700-2006 "Carbon Structural Steel," and can also refer to corresponding grades in international standards such as ASTM A36.
What does "195" mean in the Q195 grade?
It represents a minimum yield strength of 195MPa (test value for specimens ≤16mm thick).
What type of steel is Q195?
It belongs to low-carbon mild steel, with extremely low carbon content, excellent plasticity and weldability, but relatively low strength.
What is the core difference between Q195 and Q235?
Q195 has a lower yield strength (195MPa vs 235MPa), better plasticity, and is cheaper, making it suitable for light-load processing; Q235 has higher strength and is used in load-bearing structures.
