What is Q235B steel?
Q235B steel plate is a versatile and economical low-carbon steel, defined by the national standard GB/T 700-2006 'Carbon Structural Steel'. It is among the most prevalent steel varieties in China, known for its affordability and suitability for a vast array of applications where extreme performance isn’t a necessity.
The difference between Q235A and Q235B.
The difference between Q235A and Q235B steels lies in their carbon content, as outlined in the national standard GB700-88. Q235A has a precise carbon content range of 0.14-0.22%, distinguishing it from Q235B.
Typically, steel mills mark the identification plates of finished profiles before dispatch. Users can discern the material type—Q235A, Q235B, or others—from these plates. Design specifications include a pressure rating of P≤1.6MPa, a temperature range of 0~350ºC, and a steel plate thickness of at least 20mm.
The Application of Q235B Steel
Q235B steel grade is extensively utilized in civil engineering, forming the backbone of steel structures in both industrial and residential construction. It is integral to the creation of power transmission towers, equipment components, offshore structures, oil and gas platforms, automobile bridges, and a variety of other crucial infrastructures.
