Liaocheng Fengye Steel Tube Factory specializes in Q345B and 16Mn steel pipes. Q345B is a widely used steel material known for its excellent mechanical properties. The "Q" in Q345B stands for the yield strength of the material, while the number 345 indicates the minimum yield strength in megapascals (MPa). This grade is also commonly referred to as 16Mn steel, which is a type of seamless steel pipe often used in industrial applications.
16Mn is an older designation for what is now known as Q345B. The name comes from the composition of the steel: "16" refers to the carbon content, approximately 0.16%, while "Mn" stands for manganese, which is present in higher amounts—typically around 1.20% to 1.60%. These elements are listed separately due to their significant impact on the steel's properties.
16Mn belongs to the low-alloy steel family and is one of the most commonly used grades in this category. It offers a good balance of strength, toughness, and weldability, making it suitable for a wide range of structural applications.
For specific requirements, the steel can undergo additional treatments such as heat treatment or Z-direction property enhancement. Common heat treatment methods include controlled rolling and normalizing, which improve the material's microstructure and performance. The Z-direction properties refer to the steel's resistance to lamellar tearing, with options like Z15, Z25, and Z35 available depending on the application needs.
Key features of Q345B steel pipes include excellent overall performance, good low-temperature toughness, superior formability, and excellent welding and cutting characteristics. These properties make them ideal for use in various industries, including mining, transportation, and chemical machinery.
To calculate the weight of a steel pipe per meter, you can use the formula: [(Outer Diameter - Wall Thickness) × Wall Thickness] × 0.02466 = kg/m. This helps in estimating the weight for logistics, cost calculation, and structural design purposes.
The knowledge about Q345B steel pipes is provided by Shandong Liaocheng Fengye Steel Tube Factory, a trusted manufacturer with extensive experience in producing high-quality steel products for diverse industrial applications.
