What is Q235B steel?
Renowned for its versatility and affordability, Q235B steel plate is a widely used type of low carbon steel. According to the national standard GB/T 700-2006, "Carbon Structural Steel," this grade of steel is highly popular in China due to its economical nature and its suitability for a variety of applications where high performance is not a stringent requirement.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B, both falling under the category of carbon steels, is primarily linked to their carbon content as per the national standard GB700-88. Q235A boasts a carbon content ranging from 0.14-0.22%, setting it apart from its counterpart Q235B.
In typical scenarios, steel mills clearly mark the finished profiles with identification plates before they are dispatched. Users can easily determine whether the material is Q235A, Q235B, or another type by checking these plates. With a design pressure of P≤1.6MPa, a temperature range of 0~350ºC, and a steel plate thickness of >=20mm, these profiles are well-suited for varied applications.
The Application of Q235B Steel
Q235B steel grade is a trusted choice in civil engineering projects. Esteemed for its strength and reliability, Q235B is employed in crafting steel structures for both industrial and residential buildings. It also finds extensive use in components of power transmission towers, equipment elements, offshore structures, oil and gas platforms, automobile bridges, and a wide array of other structural applications.
