Product Introduction

Q215 is a commonly used low alloy structural steel in China. Its chemical composition and mechanical properties are regulated by the Chinese national standard GB/T 700-2006. It is a widely used material in China and is comparable to the ASTM A283/A283M grade D in the United States or the S235JR (1.0038):grade in Europe. 

Q215 Steel has the following general characteristics:

  • Low Carbon Content: Q215 steel has a low carbon content, typically around 0.15% to 0.2%. This low carbon content contributes to its good weldability and formability.
  • Moderate Strength: Q215 steel possesses moderate strength, with a tensile strength typically ranging from 315MPa to 430 This level of strength makes it suitable for structural applications where moderate strength is required.
  • Good Ductility: Q215 steel exhibits good ductility, allowing it to be easily formed into various shapes during manufacturing processes such as bending, rolling, and stamping.
  • Ease of Welding: Due to its low carbon content and good ductility, Q215B steel is easy to weld using common welding methods such as arc welding, MIG welding, and TIG welding.
  • Versatility: Q215steel is a versatile material that finds applications in construction, manufacturing, automotive, machinery, and other general industries where its properties meet therequirements of the application.
