Product Details

Stellite alloy valve balls and valve seats are critical components of oil well pumps used in oilfields, and their quality directly determines the service life of the pumps. Sucker rod pumps are suspended inside the tubing via support joints, suitable for oil extraction in high-temperature deep wells and deviated wells, with excellent corrosion and high-temperature resistance. Stellite alloy valve balls and valve seats are applicable to complex well conditions such as corrosion, slight sand and gas content, and high temperatures, featuring reliable operation and stable performance.

Iron-based Wrought High-temperature Alloys

Iron-based wrought high-temperature alloys are a class of metallic materials with iron (Fe) as the principal element, engineered to maintain good mechanical strength and resistance to degradation (like oxidation) at elevated temperatures, typically in the range of 540°C to 760°C (1000°F to 1400°F). The “wrought” designation indicates they are shaped by thermomechanical processes such as hot rolling, forging, or extrusion, which refine their microstructure to provide a favorable combination of strength, ductility, and fabricability. They serve as a cost-effective and highly versatile solution for a wide array of high-temperature applications, bridging the performance gap between stainless steels and more expensive nickel or cobalt-based superalloys.
