What is Q235B steel?
Q235B steel plate is an exceptional form of low carbon steel, as outlined by the prestigious national standard GB/T 700-2006 'Carbon Structural Steel.' Recognized as one of China's most prevalent and versatile steel products, Q235B is celebrated for its affordability and suitability for a wide array of applications that do not demand superior performance.
The difference between Q235A and Q235B.
The difference between Q235A and Q235B is rooted in their positions as carbon steels under the national GB700-88 standard. The distinction primarily lies in the carbon content: Q235A encompasses a carbon content range of 0.14-0.22%, setting it apart from Q235B.
Typically, steel mills ensure clear marking of finished profiles on identification plates before dispatch. Users can easily discern between Q235A, Q235B, and other materials through these identification plates. Designed for a pressure of P≤1.6MPa and operational temperatures ranging from 0~350ºC, with steel plate thicknesses of at least 20mm, these materials are optimal for diverse applications.
The Application of Q235B Steel
Q235B steel grade is a cornerstone in the realm of civil engineering, vital for crafting robust steel structures. It is extensively utilized in the construction of both industrial and residential facilities, forming the backbone of power transmission towers, key elements of essential equipment, offshore structures, oil and gas platforms, automobile bridges, and an array of other critical structures.
