Nickel alloy 625 pipe tube for marine engineering oil & gas industry
Product Description:
Alloy 625 (UN N06625) is a kind of austenitic nickel-based super alloy, in a wide range of corrosive environment with excellent oxidation resistance, corrosion resistance, crack resistance, anti-corrosion of chromium and molybdenum content on the corrosion of chlorine ion has excellent corrosion resistance, the alloy was developed for high temperature strength, its high alloy components to a wide range of oxidation and oxidation environment provides a high level of corrosion resistance to chloride stress corrosion cracking resistance.
Includes the jet engine environment and many other seawater applications, aviation components, chemical treatment equipment, nuclear water reaction components and chemical process applications.
The alloy 625 has excellent strength and toughness. The strength of the alloy 625 comes from the solid solution strengthening effect of molybdenum and niobium on nickel-chromium matrix.
From low temperature to 2000 F (1093 C).
The alloy 625 also has special fatigue resistance.
High temperature resistance, used in arc and flame spray systems, produces a dense, cohesive coating resistant to high temperature oxidation and corrosion. These elements also contribute to corrosion resistance of the alloy.
