Chemical Composition

Tiptop is specialized in providing alloy steel coiled tube, alloy steel control line, alloy steel continuous tube.

Type 625 Alloy (UNS Designation NO6625) is an austenitic nickel-based super alloy possessing excellent resistance to oxidation and corrosion over a broad range of corrosive conditions, including jet engine environments and in many other aerospace and chemical process applications. The alloy has outstanding strength and toughness at temperatures ranging from cryogenic temperature to 2000°F (1093°C). Type 625 alloy also has exceptional fatigue resistance. It derives its strength from the solid solution strengthening effects of molybdenum and columbium on the nickel-chromium matrix. Although the alloy was developed for high temperature strength, its highly alloyed composition provides a high level of general corrosion resistance to a wide range of oxidizing and non-oxidizing environments.
