Relevant Standard
The current latest version of GB/T 1591 is GB/T 1591-2018 Low-Alloy High-Strength Structural Steels. This standard specifies the designation methods for grades, order contents, dimensions, shapes, weights, technical requirements, test methods, inspection rules, packaging, marking, and quality certificates of low-alloy high-strength structural steels. It applies to low-alloy high-strength structural steel plates, strips, sections, bars, etc., used in general structures and engineering.

 

Properties

 

Good Ductility
Q295B steel exhibits excellent ductility, allowing various cold and hot forming processes (such as bending, stamping, and stretching) without cracking. This meets the manufacturing requirements for different engineering structural components.

Superior Weldability
Due to its chemical composition, this steel has good weldability. It is less prone to defects such as cracks and pores during welding, and the welded joints have high strength and toughness, ensuring the reliability of welded structures.

High Impact Toughness
With high impact toughness, Q295B steel can absorb substantial energy under impact loads, making it less likely to undergo brittle fracture. This improves the safety of structures under dynamic loads.

Good Corrosion Resistance
Thanks to the effect of alloying elements, Q295B steel has certain corrosion resistance in specific environmental conditions, which extends the service life of structures and reduces maintenance costs.
