What is Q235B steel?
Q235B steel plate, a renowned low carbon steel variety, is a staple in China's steel production. Defined under the national standard GB/T 700-2006 "Carbon Structural Steel," this steel is celebrated for its affordability and versatility. It is ideally suited for a plethora of products that do not necessitate high-performance specifications.
The difference between Q235A and Q235B.
The key distinction between Q235A and Q235B lies in their carbon content, both being carbon steels. As per the national standard GB700-88, Q235A exhibits a carbon content ranging from 0.14-0.22%, offering varied material properties.
Typically, steel mills emboss the identification plates on finished profiles, ensuring easy recognition of materials as Q235A, Q235B, or others. Designed for pressures up to P≤1.6MPa and temperatures from 0~350ºC, these profiles boast a steel plate thickness of >=20mm.
The Application of Q235B Steel
Q235B steel is integral to civil engineering, providing robust solutions for both industrial and residential constructions. Its adaptability extends to power transmission tower components, equipment elements, offshore structures, oil and gas platforms, vehicle bridges, and a myriad of structural applications.
