Inconel 690 bar

Specifications

The chemical compostion of the inconel 690 nickel base alloy(%):

The physical properties of the inconel 690 nickel base alloy:

INCONEL 690 Nickel base Alloy is a high-chromium nickelalloy having excellent resistance to manycorrosive aqueous media and high-temperatureatmospheres. The alloy's high chromium contentgives it excellent resistance to

aqueous corrosionby oxidizing acids (especially nitric acid) andsalts, and to sulfidation at high-temperatures.In addition to its corrosion resistance, alloy 690has high strength,

good metallurgical stability,and favorable fabrication characteristics.

Inconel 690 Rod Elongation 30%, HB 195 Y.S. 240MPa, U.T.S. 550MPa ISO 9001:2000, SGS

Inconel 690 Rod

 We can supply many different style, such as ring, flange, sheet, tube, rod, wire and so on.

Characteristic as below

1.Good corrosion resistance property for the reduction, oxidation, Nitric and other media.

2.Good stress corrosion cracking resistance property in both room temperature and high temperature.

3.Good corrosion resistance of the dry chlorine and chlorine hydride.

4.Good mechanical property when below zero, room temperature and high temperature.

5.Good anti-creep rupture strength, with the recommendation of 700 or above working environment.

Metallurgical structure

600 is face-centered cubic lattice structure.

Corrosion resistance

600 have corrosion resistance to many kinds of corrosive media. Chromium content made it with better corrosion resistance than Nickel 99.2 (alloy200) and Nickel 99.2 ( alloy201,low carbon) in the oxidize environment. Meantime, high Nickel content make this alloy with good corrosion resistance in the reduction condition and alkaline solution, and also effective avoid chlorine-iron stress corrosion cracking. 600 have good corrosion resistance in the acid, acetic acid, formic acid, stearic acid and other organic acid, with medium corrosion resistance in the inorganic acid. The alloy with excellent corrosion resistance in the first and the second recycling use of the high purity water in the nuclear reactor. Especially excellent corrosion resistance to dry chlorine and chlorine hydride applied up to 650 . When nder the high temperature, annealing and state solution alloy have good antioxidant off and high-intensity in the air, 600 can resist the ammonia, nitriding and carburizing atmosphere, but at the turn of the changes in redox conditions, it will be corrosion by parts of oxidation media.( such as green death liquid)

Application fields

1. Erosion thermocouple sheath of the atmosphere

2.Vinyl chloride monomer production: corrosion resistance to chlorine, hydrogen chloride, oxidation and carbonation.

3. Oxide shaft chloride converted to six fluoride: hydrogen fluoride anti-corrosion.

4. Corrosive alkali metal produce and usage filed, especially the sulfide use environment.

5. Use Chlorine produce titanium dioxide

6.Organic or inorganic chlorine produce: corrosion resistance to chlorine and fluoride.

7. Nuclear reactor

8.Heat treatment furnace flask and components, especially in the carbonization and nitride atmosphere.

9. Petrochemical works production of catalytic regeneration in the application of more than 700 recommended the use of 600, in order to obtain a longer service life.
