What is Q235B steel?
Q235B steel plate is a versatile type of low carbon steel, as clearly defined by the national standard GB/T 700-2006 'Carbon Structural Steel'. It stands out as one of the most prevalent steel products across China due to its cost-effectiveness and adaptability for applications not demanding high-performance attributes.
The difference between Q235A and Q235B.
Understanding the nuances between Q235A and Q235B: Both are carbon steels as per the national standard GB700-88. The primary distinction lies in their carbon content, where Q235A features a carbon content ranging from 0.14-0.22%. This subtle difference significantly influences their performance and application.
Before dispatch from the factory, steel mills meticulously mark the finished profiles on identification plates. These markings allow users to easily verify whether the material is Q235A, Q235B, or another material entirely. The design pressure is P≤1.6MPa, suitable for use in temperatures from 0 to 350ºC, and the steel plate thickness is >=20mm.
The Application of Q235B Steel
Renowned for its robustness, Q235B steel is extensively employed in civil engineering projects. It forms the backbone of steel structures used in constructing industrial and residential buildings, power transmission towers, and components of equipment. Additionally, it's pivotal in offshore structures, oil and gas platforms, automobile bridges, and a myriad of other essential structures.
