What is Q235B steel?
Q235B steel plate, a versatile low carbon steel defined by the national standard GB/T 700-2006 "Carbon Structural Steel," stands as one of the most prevalent steel products in China. Its affordability and adaptability make it ideal for a wide range of applications that don't demand exceptional performance, offering a reliable and economical solution for various structural needs.
The difference between Q235A and Q235B.
Q235A and Q235B are both carbon steels, with distinctions primarily in carbon content as outlined in the national standard GB700-88. Q235A contains 0.14-0.22% carbon, which slightly differentiates it from Q235B, offering subtle variations in material properties. Understanding these differences is crucial for selecting the right steel for specific applications.
Typically, steel mills meticulously mark finished profiles on identification plates before dispatch. These plates enable users to determine whether the material is Q235A, Q235B, or another type. With design pressure up to 1.6MPa and operational temperatures ranging from 0 to 350ºC, the steel plate boasts a thickness of at least 20mm, ensuring robust performance and reliability.
The Application of Q235B Steel
Q235B steel grade is integral to modern civil engineering projects, forming the backbone of steel structures in both industrial and residential constructions. It is essential in building parts of power transmission towers, critical equipment elements, offshore structures, oil and gas platforms, automobile bridges, and various infrastructure projects, showcasing its broad utility and strength.
