What is Q235B steel? Discover the defining qualities and unparalleled versatility of Q235B steel—your go-to material for a myriad of industrial applications.
Q235B steel plate is renowned for its role as a low carbon steel that perfectly balances affordability with functionality. According to the national standard GB/T 700-2006 'Carbon Structural Steel,' Q235B stands out as one of the most relied-upon steel products in China. Its cost-effectiveness and adaptability make it ideal for various projects where exceptionally high performance is not a prerequisite.
The difference between Q235A and Q235B.
The difference between Q235A and Q235B lies primarily in their carbon composition, and both are classified under the umbrella of carbon steels. According to the national standard GB700-88, the distinction is clear: Q235A has a carbon content ranging from 0.14-0.22%, making it unique from Q235B.
In standard practice, steel mills emboss the identifying details on the profile plates before dispatch. This allows you to ascertain if the material is Q235A, Q235B, or another variant just by checking the identification plate. It’s crafted to endure design pressures ≤1.6MPa and withstands temperatures between 0~350ºC, with a plate thickness of at least 20mm.
The Application of Q235B Steel
With its robust properties, steel grade Q235B is a staple in civil engineering. It is extensively implemented in constructing both industrial and residential structures. From power transmission towers and elements of machinery to dynamic offshore structures and resilient oil and gas platforms, Q235B steel is also vital in creating durable automobile bridges and a wide array of other structural marvels.
