What is Q235B steel?
Q235B steel plate is a versatile, low-carbon steel that aligns with the national standard GB/T 700-2006 "Carbon Structural Steel." Known for its affordability, Q235B is predominantly used in China and suitable for a wide range of applications that do not require exceptional strength or advanced performance. It is the go-to choice for many due to its cost-effectiveness and reliable performance.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies primarily in their carbon content, as detailed in the national standard GB700-88. Both are carbon steels; however, Q235A features a carbon content ranging from 0.14% to 0.22%. This subtle difference can influence the steel's properties and suitability for various applications, making the identification crucial for optimal use.
Typically, steel mills provide identification plates for finished profiles before they leave the factory. These plates help users determine if the material is Q235A, Q235B, or another type of steel. With a design pressure of P≤1.6MPa and temperature usability between 0 to 350ºC, this steel is suitable for plates with a thickness of at least 20mm, ensuring durability and reliability in varied conditions.
The Application of Q235B Steel
Q235B steel grade is integral to civil engineering, offering robust solutions for both industrial and residential structures. Its versatility extends to the construction of power transmission towers, key components of equipment, offshore structures, and vital infrastructure such as oil and gas platforms and automobile bridges. Its widespread use showcases its adaptability and strength in demanding environments.
