ALLOY 925 TUBE
Mechanical Tubing & OCTG
This is an age-hardenable Nickel based alloy containing Iron and Chromium as major additions, and also additions of Molybdenum, Copper, Titanium and Aluminum. A combination of high strength and corrosion resistance make it suitable in applications such as valves, hangers, packers, and tubular, in sour gas environments. It can also be used for fasteners, and for pump shafts operating within marine environments.
The combination of Nickel and Chromium renders protection in both oxidising and reducing atmospheres. The high Nickel content also gives resistance to chloride -ion stress -corrosion cracking. Pitting and crevice corrosion resistance is also excellent. The alloy is produced by a vacuum remelt process.
When bill of material requirements can be matched against the wide stock sizes available considerable cost savings in both raw material supply and manufacturing are achievable against the comparable bar product.
