What is Q235B steel?
Q235B steel plate is a widely embraced type of low carbon steel, defined meticulously under the national standard GB/T 700-2006 for 'Carbon Structural Steel'. Known for its affordable pricing, Q235B stands as one of China's most prevalent steel products, ideal for applications not demanding high-performance features.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B steels lies in their classification as carbon steels according to the national standard GB700-88. The primary differentiator is their carbon content, with Q235A comprising a carbon range of 0.14-0.22%.
Typically, steel mills mark the finished profiles with identification plates before dispatch. This enables users to discern if the material is Q235A, Q235B, or another type. Design parameters include pressure P≤1.6MPa, operating temperature range 0~350ºC, and a minimum steel plate thickness of 20mm.
The Application of Q235B Steel
Steel grade Q235B is extensively utilized in civil engineering projects. It is instrumental in crafting steel structures for industrial and residential buildings, components of power transmission towers, equipment parts, offshore installations, oil and gas platforms, automotive bridges, and a variety of other constructions.
