Centrifugal cast ZG40Cr26Ni4Mn3NRe seamless steel pipes are high-temperature alloy steel pipes produced by the centrifugal casting process. They are specially designed for extreme working conditions and possess excellent high-temperature resistance, corrosion resistance and wear resistance. They are commonly used in power industry for slag discharge pipes of fluidized bed boilers and high-temperature pipelines, capable of withstanding slag erosion and high-temperature flue gas corrosion. In the metallurgical and chemical industries, they are used for transporting high-temperature corrosive media, such as slag discharge pipes in metallurgy and chemical reactor liners.
Products Description
Material Characteristics
Chemical composition
Core elements: Chromium (Cr) 26%, Nickel (Ni) 4%, Manganese (Mn) 3%, Rhenium (Re), etc., form a stable high-temperature alloy structure.
High chromium content (≥26%) significantly enhances oxidation resistance, while nickel and rhenium elements enhance high-temperature anti-welding deformation ability.
Mechanical properties
High-temperature strength: The long-term working temperature can reach 1000 - 1200℃, suitable for fluidized bed boilers, metallurgical slag discharge and other high-temperature environments.
Wear resistance: The centrifugal casting process ensures uniform and dense pipe walls, and its anti-wear performance is superior to that of ordinary steel pipes.
Production Process
Centrifugal casting technology
The molten metal is injected into a high-speed rotating mold, and through centrifugal force, the alloy layer and the carbon steel layer achieve a metallurgical bond. The wall thickness is uniform and the density is high.
Process advantages: Avoid traditional welding defects, and the shear strength of the composite interface is ≥ 300 MPa.
Finished product processing
Heat treatment is used to eliminate internal stress, and non-destructive testing (ultrasonic, radiographic) is carried out to ensure the absence of defects such as pores and inclusions.
