Properties of Inconel Needle Valves

High tensile, creep, and rupture strength; outstanding fatigue and thermal-fatigue strength; oxidation resistance; and excellent weldability and brazeability are the properties of INCONEL alloy 625 that make it interesting to the aerospace field.

In brief Inconel Needle Valves has –

  1. Good resistance to acids, such as sulfuric, phosphoric, nitric, and hydrochloric
  2. Almost completely free from chloride induced stress corrosion cracking
  3. Excellent mechanical properties at both extremely low and extremely high temperatures
  4. Outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion
  5. High resistance to oxidation at elevated temperatures


Applications of Inconel Needle Valves

The properties of INCONEL alloy 625 that make it an excellent choice for sea-water applications are freedom from local attack (pitting and crevice corrosion), high corrosion-fatigue strength, high tensile strength, and resistance to chloride-ion stress-corrosion cracking.

Industries in which Inconel Needle Valves is used?

  1. Chemical and petrochemical processing
  2. Components where exposure to high mechanical stress and sea water are required
  3. Flare stacks on offshore oil platforms
  4. Gas turbines, rocket motors/engines, and space craft
  5. Pollution control equipment
  6. Nuclear reactors



Strength of INCONEL alloy 625 is derived from the stiffening effect of molybdenum and niobium on its nickel-chromium matrix; thus precipitation hardening treatments are not required. This combination of elements also is responsible for superior resistance to a wide range of corrosive environments of unusual severity as well as to high-temperature effects such as oxidation and carburization.
