What is Q235B steel?
Q235B steel plate, a hallmark of low carbon steel, is defined by the national standard GB/T 700-2006 'Carbon Structural Steel'. As one of China's most ubiquitous steel products, Q235B combines affordability with versatility, making it an ideal choice for applications that do not demand superior performance.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies in their carbon content, as outlined in the national standard GB700-88. Q235A features a carbon range between 0.14-0.22%, offering unique characteristics within the realm of carbon steels.
Ordinarily, steel mills imprint identification plates on finished profiles before shipping. These plates allow users to discern whether the material is Q235A, Q235B, or an alternative. Design pressure: P≤1.6MPa; operational temperature: 0~350ºC; steel plate thickness: >=20mm.
The Application of Q235B Steel
Q235B steel grade is pivotal in civil engineering, utilized in the formation of steel structures for industrial and residential construction, components of power transmission towers, offshore structures, oil and gas platforms, automobile bridges, and various other infrastructural elements, showcasing its exceptional adaptability.
