What is Q235B steel?
Q235B steel plate is a highly versatile low carbon steel, defined precisely by the national standard GB/T 700-2006 'Carbon Structural Steel'. As one of China's most prevalent steel products, Q235B offers an affordable solution for a multitude of applications, making it ideal for projects that do not demand high performance specifications. Its budget-friendly nature combined with its adaptability ensures it remains a staple material in various industries.
The difference between Q235A and Q235B.
The difference between Q235A and Q235B: These steels, classified as carbon steels, are distinguished primarily by carbon content as per the national standard GB700-88. Q235A contains a carbon range of 0.14-0.22%. This subtle variation in composition influences their respective applications, ensuring each is suited to specific demands according to structural requirements.
Typically, steel mills diligently mark the identification plates of finished profiles before they depart the factory, enabling users to verify if their material is Q235A, Q235B, or an alternative specification. The design pressure is P≤1.6MPa, with an operational temperature ranging from 0~350ºC, and a minimum steel plate thickness of 20mm, ensuring resilience and reliability for diverse applications.
The Application of Q235B Steel
Steel grade Q235B is indispensable for executing pivotal civil engineering solutions. Renowned for its strength and flexibility, it is crafted into steel structures essential for constructing industrial and residential facilities. Its applications span across power transmission tower components, parts of complex equipment, offshore structures, oil and gas platforms, automobile bridges, and a wide array of essential infrastructural projects.
