What is Q235B Steel?
Q235B steel plate is a remarkable type of low carbon steel, beautifully defined by the national standard GB/T 700-2006 'Carbon Structural Steel.' Esteemed as one of the most prevalent steel products in China, Q235B boasts affordability and adaptability for a myriad of applications where supreme performance isn't a foremost requirement.
The Difference Between Q235A and Q235B
Q235A and Q235B are both distinguished carbon steels under the national standard GB700-88. The primary distinction lies in their carbon content; Q235A contains a carbon percentage ranging from 0.14% to 0.22%, illuminating its slightly varied properties.
Typically, steel mills imprint essential data on the identification plates of finished profiles before dispatch. Users can confidently determine whether the material is Q235A, Q235B, or another type based on these identification plates. With design parameters of pressure P≤1.6MPa, an operating temperature range of 0~350ºC, and a thickness of steel plates being 20mm or more, Q235B stands ready to meet diverse demands.
The Applications of Q235B Steel
Q235B, a robust steel grade, is actively employed in a plethora of civil engineering projects. It forms the backbone of steel structures for the construction of both industrial and residential buildings, segments of power transmission towers, vital components of equipment, and offshore constructions, including oil and gas platforms, automobile bridges, and numerous other infrastructural marvels.
