What is Q235B steel?
Delve into Q235B steel plate-a versatile and economical low carbon steel. As defined by the national standard GB/T 700-2006 "Carbon Structural Steel," Q235B stands out as one of China's most prevalent steel products. Known for its cost-effectiveness, Q235B is ideal for diverse applications that do not demand high performance, making it the perfect choice for various projects.
The difference between Q235A and Q235B.
When comparing Q235A and Q235B, both are recognized as carbon steels under the national standard GB700-88. The key differentiation lies in their carbon content: Q235A has a carbon content range of 0.14-0.22%. This variance in carbon level influences their application and performance, distinguishing their respective uses.
Typically, steel mills provide clear identification on finished profiles via identification plates before dispatch. These plates enable users to easily ascertain whether the material is Q235A, Q235B, or alternative materials. With design parameters set at a pressure P≤1.6MPa and a usage temperature between 0~350ºC, the minimum steel plate thickness stands at >=20mm, ensuring reliability and safety.
The Application of Q235B Steel
Q235B steel is a cornerstone in civil engineering projects, widely employed in constructing robust steel structures. From industrial to residential facilities, Q235B steel forms the backbone of power transmission towers, equipment elements, offshore structures, oil and gas platforms, automobile bridges, and a multitude of other infrastructure projects, showcasing its versatility and strength.
