What is Q195 steel?
Q195 is ordinary carbon structural steel, belonging to the category of low-carbon steel. "Q" represents yield strength, and "195" means that the yield strength is ≥195MPa when the thickness is ≤16mm. It is a commonly used and economical steel in the construction industry.
What are the standards for Q195?
It complies with GB/T 700-2006 "Carbon Structural Steel." Chemical composition, mechanical properties, and delivery condition must all meet the requirements of this standard.
What is the core difference between Q195 and Q235?
Q195 has a lower yield strength (Q195≥195MPa, Q235≥235MPa), better plasticity and weldability, and lower cost, but weaker load-bearing capacity, making it only suitable for secondary building components.
What is the carbon content range of Q195?
The carbon content is 0.06%-0.12%. Its low-carbon characteristics determine its excellent plasticity and weldability, which are core advantages in construction processing.
What are the delivery conditions for Q195?
Mainly hot-rolled, but cold-rolled, galvanized, and color-coated finishes can also be provided to meet the needs of different construction scenarios.
