What is Q235B steel?
Q235B steel plate is a versatile low carbon steel, renowned for its cost-effectiveness and widespread utility within China's manufacturing industry. Defined under the national standard GB/T 700-2006 'Carbon Structural Steel,' Q235B is a favorite choice for applications where vigorous performance is not paramount.
The difference between Q235A and Q235B.
The difference between Q235A and Q235B: Both are carbon steels categorized under the national standard GB700-88. The key distinction lies in their carbon content, where Q235A features a carbon range of 0.14-0.22%, impacting their respective performance attributes.
Under standard manufacturing protocols, steel mills distinctly label finished profiles on identification plates prior to dispatch. This enables users to discern between Q235A, Q235B, or alternative materials. Specifications include design pressure P≤1.6MPa, operational temperature 0~350ºC, with steel plate thickness of >=20mm.
The Application of Q235B Steel
Q235B steel grade is prominently utilized in civil engineering projects. It is foundational for crafting steel structures in industrial and residential buildings, power transmission towers, equipment components, offshore structures, oil and gas platforms, and automobile bridges, among other significant constructions.
