Inconel 600 Bolts

Inconel 600 UNS NO6600, W.Nr.2.4816, alloy600, NA14

Alloy 600 is a nickel-chromium-iron-based solid-solution strengthened alloy, which has good high temperature corrosion resistance and oxidation resistance, excellent cold and hot processing and welding process performance, and has satisfactory thermal strength and high plasticity below 700 °C. Alloys can be strengthened by cold working or joined by resistance welding, fusion welding or brazing.

Corrosion Resistance

Alloy 600 is corrosion resistant to various corrosive media. The chromium content gives the alloy better corrosion resistance under oxidizing conditions than Nickel 99.2 (Alloy 200) and Nickel 99.2 (Alloy 201, low carbon). At the same time, the higher nickel content makes the alloy have good corrosion resistance in reducing conditions and alkaline solutions, and can effectively prevent chlorine-iron stress corrosion cracking.

 

Alloy 600 has good corrosion resistance in acetic acid, acetic acid, formic acid, stearic acid and other organic acids, and has moderate corrosion resistance in inorganic acids. Excellent in high purity water used in primary and secondary cycles of nuclear reactors

 

corrosion resistance.

 

Especially outstanding performance is the resistance to dry chlorine gas and chlorine

 

Hydrogen corrosion, the application temperature of 650 ℃. At high temperature, the annealed and solution treated alloys have good resistance to oxidation spalling and high strength in air.

 

The alloy is also resistant to ammonia gas and nitriding and carburizing atmospheres, but the alloy will be corroded by partially oxidizing media when the redox conditions alternate.

 

Application Field

1. Aero engine parts

2. Thermowells in aggressive atmospheres

3. The fields of production and use of corrosive alkali metals, especially the environment where sulfides are used

4. Catalytic regenerators in petrochemical production

5. Nuclear Reactor
