In the Chinese GB standard, "Q" stands for "Qu Fú Diǎn," which translates to Yield Point. The number following it (e.g., 235) represents the minimum yield strength of the material in megapascals (MPa). The letter at the end, such as "B," indicates the quality grade, which relates to impact test requirements. Therefore, Q235B has a minimum yield strength of 235 MPa and is a Grade B quality steel.
The main difference is strength. Q295 has a higher minimum yield strength (295 MPa) and tensile strength compared to Q235B (235 MPa). This makes Q295 suitable for applications that require greater load-bearing capacity and structural integrity. Q235B is a more common, all-purpose steel for general construction and fabrication where the strength requirements are not as demanding.
Absolutely. Q235B is one of the most widely used steels for fabrication precisely because of its excellent welding performance and good plasticity. It can be easily welded using standard methods without the need for preheating in most situations, and it is also easy to cut, bend, and machine, making it highly efficient for industrial production.
