What is Q235B steel?
Q235B steel plate represents a highly versatile and economically efficient low carbon steel. As per the national standard GB/T 700-2006 'Carbon Structural Steel', it is one of China's most prevalent steel products. Its affordability makes it an ideal choice for a wide range of applications, particularly those not demanding exceptional performance.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies in their carbon content, both being carbon steels under national standard GB700-88. Q235A's carbon content ranges from 0.14 to 0.22%, specifying its unique material properties.
Typically, steel mills provide clear identification on finished profiles before dispatch. This allows users to determine the material type, whether Q235A, Q235B, or others, through these identification plates. The material is designed to withstand pressure up to 1.6MPa; operational temperatures between 0 to 350ºC; and a minimum steel plate thickness of 20mm.
The Application of Q235B Steel
Featuring remarkable adaptability, steel grade Q235B is extensively utilized in civil engineering projects. It is integral to constructing industrial and residential structures, components of power transmission towers, equipment elements, offshore establishments, oil and gas platforms, automotive bridges, and numerous other structural frameworks.
