What is Q235B steel?
Q235B steel plate is a renowned low carbon steel that is widely recognized under the national standard GB/T 700-2006 'Carbon Structural Steel'. As one of the most prevalent steel products in China, Q235B stands out for its affordability and versatility, making it an excellent choice for a wide array of applications where high performance is not essential.
The difference between Q235A and Q235B.
In exploring the differences between Q235A and Q235B, both of which are carbon steels, the national standard GB700-88 primarily distinguishes them by the carbon content. Q235A contains carbon ranging from 0.14% to 0.22%, highlighting the subtle variances that define their unique applications and performance characteristics.
Typically, steel mills detail the composition of finished profiles on identification plates before dispatch. This allows users to easily identify whether the material is Q235A, Q235B, or another variant. It supports design pressures up to 1.6MPa, can be used in temperatures ranging from 0 to 350ºC, and is available in thicknesses starting from 20mm.
The Application of Q235B Steel
Q235B steel grade is a cornerstone in civil engineering, where its strength and reliability are harnessed to construct a wide range of structures. It is instrumental in building both industrial and residential facilities, components of power transmission towers, vital elements of various equipment, as well as offshore structures, oil and gas platforms, and automobile bridges.
