What is Q235B steel? Q235B steel is a highly popular and widely used low carbon steel variant in China. Recognized under the national standard GB/T 700-2006 for Carbon Structural Steel, this material is prized for its affordability and adaptability, making it an ideal choice for a variety of applications where high performance is not a critical requirement.
Q235B steel plate is a kind of low carbon steel. The national standard GB/T 700-2006 "Carbon Structural Steel" has a clear definition. Q235B is one of the most common steel products in China. It is cheap and can be used for most products that do not require high performance.
The difference between Q235A and Q235B: Delve into the distinctions between Q235A and Q235B, both belonging to the family of carbon steels. Understanding these differences is crucial for selecting the right material for your specific needs.
The difference between Q235A and Q235B: steels are all carbon steels. In the national standard GB700-88, the material distinction between Q235A and Q235B is mainly in terms of the carbon content of steel. The material of Q235A has a carbon content of 0.14-0.22%;
Under normal circumstances, steel mills mark the finished profiles on the identification plates before they leave the factory. The user can judge whether the material is Q235A, Q235B, or other materials on the identification plate. Design pressure P≤1.6MPa; use temperature 0~350ºC; steel plate thickness>=20mm
The Application of Q235B Steel: The versatility of Q235B steel makes it an indispensable asset for civil engineering projects. This steel grade is utilized in constructing industrial and residential facilities, forming the backbone of power transmission towers, and shaping offshore structures, oil and gas platforms, vehicle bridges, and more. Its resilience and reliability make it a preferred choice for diverse applications.
Steel grade Q235B is actively used to implement civil engineering solutions. Steel structures are made from Q235B steel for the construction of industrial and residential facilities, parts of power transmission towers, elements of equipment, offshore structures, oil and gas platforms, automobile bridges and other structures.
