What is Q235B Steel?
Q235B steel plate is a distinguished type of low carbon steel with a solid reputation across diverse sectors. As defined by the national standard GB/T 700-2006 "Carbon Structural Steel," Q235B stands out as one of China's most utilized steel products. Its affordability makes it an optimal choice for manufacturing a variety of products where high performance is not a strict requirement.
The Difference Between Q235A and Q235B
The difference between Q235A and Q235B: These types of carbon steels, both outlined in the national standard GB700-88, mainly differ in their carbon content. Q235A features a carbon content range of 0.14-0.22%, distinguishing it from Q235B.
Under regular production scenarios, steel mills mark their finished profiles with identification plates prior to shipping. Customers can ascertain whether the material is Q235A, Q235B, or another by inspecting these plates. This process ensures the steel plate aligns with design parameters: Pressure P≤1.6MPa; operational temperature 0~350ºC; thickness >=20mm.
The Application of Q235B Steel
Q235B steel grade is highly preferred in the realm of civil engineering due to its versatility and strength. This steel is routinely used to fabricate sturdy steel structures for industrial and residential buildings, components of power transmission towers, equipment elements, offshore structures, oil and gas platforms, automobile bridges, and many other critical constructions.
