What is Q235B steel?
Q235B steel plate exemplifies a versatile and popular low carbon steel, clearly defined within the national standard GB/T 700-2006 for 'Carbon Structural Steel.' As one of China's most frequently used steel products, Q235B is notable for its affordable pricing and broad applicability across various products that do not demand high performance attributes.
The difference between Q235A and Q235B.
The distinction between Q235A and Q235B carbon steels lies within the parameters set by the national standard GB700-88, focusing primarily on carbon content. Specifically, Q235A features a carbon content range of 0.14-0.22%;
Under standard conditions, steel mills emboss identification plates on finished profiles prior to dispatch. These plates enable users to ascertain whether the material is Q235A, Q235B, or an alternative. Design pressure is P≤1.6MPa; operational temperature spans 0~350ºC; with a steel plate thickness requirement of >=20mm.
The Application of Q235B Steel
Q235B steel is strategically utilized within the realm of civil engineering solutions. This steel grade is integral to the fabrication of steel structures for the erection of industrial and residential edifices, components of power transmission towers, and elements of equipment. It is also used in constructing offshore structures, oil and gas platforms, as well as automobile bridges and various other infrastructures.
