What is Q235B steel?
Q235B steel plate is a versatile type of low carbon steel. Defined by the national standard GB/T 700-2006 'Carbon Structural Steel', it is one of the most prevalent steel products in China. Its affordability makes it ideal for numerous products where high performance is not essential.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B lies in their classification as carbon steels. According to the national standard GB700-88, the primary difference is the carbon content: Q235A contains carbon in the range of 0.14-0.22%.
Typically, steel mills label finished profiles on identification plates prior to their dispatch. Users can determine whether the material is Q235A, Q235B, or another variant by checking these plates. The standard design pressure is P≤1.6MPa, with an operational temperature range of 0~350ºC. Steel plate thickness is no less than 20mm.
The Application of Q235B Steel
Steel grade Q235B is instrumental in facilitating civil engineering endeavors. It is employed in creating steel structures for both industrial and residential buildings, components of power transmission towers, equipment elements, offshore constructions, oil and gas platforms, automobile bridges, and various other infrastructure projects.
