What is Q235B steel?
Q235B steel plate is a versatile low carbon steel, as defined by the national standard GB/T 700-2006 'Carbon Structural Steel'. It is one of China's most prevalent steel products, known for its cost-effectiveness and suitability for applications where high performance is unnecessary.
The difference between Q235A and Q235B.
The difference between Q235A and Q235B lies primarily in their carbon content, both being carbon steels. As per national standard GB700-88, Q235A has a carbon content ranging from 0.14% to 0.22%.
Typically, steel mills mark the finished profiles on identification plates before dispatch, allowing users to identify materials such as Q235A, Q235B, or others. Design parameters include pressure P≤1.6MPa, temperature range 0~350ºC, and a steel plate thickness of >=20mm.
The Application of Q235B Steel
Q235B steel grade is highly favored for civil engineering projects. It is fundamental in constructing industrial and residential buildings, power transmission towers, components of equipment, offshore structures, oil and gas platforms, automobile bridges, and other significant structures.
