Introduction and Differences of Ball Flat Steel Grades

TAGS: Ball flat steel | grade | Q235B | Q345B | SS400 | A36 | S235JR | steel |

Here is an introduction to several common grades of ball flat steel and their differences:

Q235B: Q235B is a structural steel grade in the Chinese standard GB/T 700. It is a low carbon steel with good weldability, ductility, and mechanical properties. It is widely used for general structural purposes.

Q345B: Q345B is a structural steel grade in the Chinese standard GB/T 1591. Compared to Q235B, Q345B has higher strength and better corrosion resistance. It is often chosen for structural engineering projects that require higher strength.

SS400: SS400 is a structural steel grade in the Japanese standard JIS G3101. It is similar to Q235B in China and possesses good weldability and ductility. It finds extensive use in various structural engineering applications.

A36: A36 is a carbon structural steel grade in the American standard ASTM A36/A36M. It is commonly known as low carbon steel. A36 offers excellent workability and weldability and is widely used in construction, manufacturing, and aerospace industries.

S235JR: S235JR is a non-alloy structural steel grade in the European standard EN 10025-2. It exhibits good ductility and weldability and is frequently used in general structural engineering applications.

The differences among these ball flat steel grades lie in their chemical composition, mechanical properties, and the specific national/regional standards they adhere to. Different grades of ball flat steel exhibit varying hardness, strength, toughness, and corrosion resistance to suit diverse engineering requirements. Selecting the appropriate grade should be based on specific project demands, relevant standards, and guidelines, and professional engineer recommendations.
