Shandong Q345R seamless steel pipe and Q345R seamless steel pipe characteristics
Shandong Q345R seamless steel pipes are widely used in boiler and pressure vessel applications due to their excellent mechanical properties and cost-effectiveness. Q345R is a low-alloy structural steel that was developed by combining several similar grades such as 16Mn, 16MnR, and 19Mng. It is commonly used in industrial and engineering fields where strength and durability are essential. The steel is typically delivered in either hot-rolled or normalized condition, which enhances its overall performance and machinability.
Compared to Other common steels like 20G, Q345R offers slightly higher tensile strength, ranging from 450 MPa to 655 MPa, while its elongation is around 19% to 21%, which is slightly lower than the 24% of 20G. Despite this, it maintains good toughness and resistance to deformation under high-pressure conditions. Its low manganese content makes it more economical without compromising on quality, making it a popular choice for various pressure vessel applications.
The production of Q345R seamless steel pipes follows the national standard GB713-2008, ensuring that all products meet strict quality and safety requirements. Shandong Seamless Steel Tube Factory provides detailed information and technical support for those looking to understand the characteristics and applications of Q345R steel pipes. Whether you're working on a boiler system, chemical plant, or any other industrial project, Q345R is a reliable and versatile material option.
