What is Q235B Steel?
Q235B steel plate represents a remarkable balance of affordability and versatility. Defined under the national standard GB/T 700-2006 'Carbon Structural Steel', this low carbon steel is a staple in China's steel industry. Its cost-effectiveness makes it highly popular for applications where extreme performance isn't a necessity, yet reliability and durability are still required.
The Difference Between Q235A and Q235B
Diving deep into the difference between Q235A and Q235B, both of which belong to the carbon steel family, we find distinct variations in carbon content as specified by national standard GB700-88. Q235A is characterized by a carbon content range of 0.14-0.22%, while each grade offers unique advantages suited for different industrial purposes.
Typically, before departing from the steel mill, finished profiles are clearly marked on identification plates, allowing users to ascertain whether the material is Q235A, Q235B, or another variant. These plates also provide critical specifications: design pressure P ≤ 1.6MPa, operational temperatures from 0 to 350ºC, and a minimum steel plate thickness of 20mm.
The Application of Q235B Steel
Q235B Steel is a stalwart in civil engineering, offering strength and adaptability. This grade of steel is indispensable in crafting steel structures for diverse applications including industrial and residential buildings, components of power transmission towers, and essential parts for offshore structures. It is the backbone of oil platforms, automobile bridges, and many other critical constructions.
