What is Q235B steel?
Q235B steel plate represents a versatile and economical option among low carbon steels. As per the national standard GB/T 700-2006 'Carbon Structural Steel', it is distinctly defined. Recognized as one of the most prevalent steel products in China, Q235B offers affordability and suits a majority of applications that do not necessitate elevated performance standards.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies in their categorization as carbon steels. Referencing the national standard GB700-88, the variance is primarily in the carbon content: Q235A features a carbon range of 0.14-0.22%, making it distinct from its counterpart.
Typically, steel mills imprint the finished profiles on identification plates prior to dispatch. This allows users to easily ascertain whether the material is Q235A, Q235B, or any other type indicated on the plate. It is suitable for a design pressure P≤1.6MPa, operational temperatures between 0~350ºC, and a steel plate thickness of at least 20mm.
The Application of Q235B Steel
Q235B steel grade finds extensive application in civil engineering solutions. It is crucial in fabricating steel structures for both industrial and residential construction projects. Additionally, it serves as essential components in power transmission towers, parts of offshore structures, elements for oil and gas platforms, automotive bridges, and myriad other constructions.
