What is Q235B steel?
Q235B steel plate is a widely recognized low carbon steel known for its versatility. Defined by the national standard GB/T 700-2006 'Carbon Structural Steel,' Q235B is one of China's most prevalent steel products. It boasts affordability and is suitable for a majority of applications that do not demand superior performance metrics.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies within their classification as carbon steels. According to the national standard GB700-88, the primary differentiation is in the carbon content. Q235A has a carbon content ranging between 0.14% and 0.22%;
Typically, steel mills imprint crucial profile information on identification plates before dispatch. This allows users to determine if a material is Q235A, Q235B, or another classification. Parameters include design pressure P≤1.6MPa; operational temperature from 0 to 350ºC; and a steel plate thickness of no less than 20mm.
The Application of Q235B Steel
Q235B steel grade is extensively employed in executing civil engineering projects. It serves as a fundamental material in constructing industrial and residential structures, power transmission towers, equipment components, offshore installations, oil and gas platforms, automotive bridges, and various other structural entities.
