What is Q235B steel? Discover the foundation of modern architecture with Q235B steel, a staple in the world of construction materials. This low carbon marvel is renowned for its exceptional balance of quality and cost-effectiveness, making it a go-to choice for various applications.
Q235B steel plate is a highly versatile low carbon steel, defined by the national standard GB/T 700-2006 "Carbon Structural Steel." It stands out as one of China's most prevalent steel products due to its affordability and adaptability, suitable for a broad range of products without demanding high-performance characteristics.
The difference between Q235A and Q235B: Uncover the distinctions between these two popular carbon steels. Delve into the specifics to understand which variant best suits your engineering requirements.
The difference between Q235A and Q235B lies primarily in their carbon content, as delineated by the national standard GB700-88. Q235A features a carbon content ranging from 0.14-0.22%, offering nuanced options for material selection based on project needs.
Typically, steel mills label finished profiles on identification plates prior to dispatch. Users can determine if the material is Q235A, Q235B, or another type from these plates. With a design pressure of P≤1.6MPa, an operational temperature range of 0~350ºC, and a minimum steel plate thickness of 20mm, these specifications ensure optimal performance.
The Application of Q235B Steel: Discover the vast potential of Q235B steel in various construction endeavors.
