Weld Neck B564 N08800 Incoloy 800 Alloy Steel Flanges

Weld Neck Flange 150Lb B564 N08800 Incoloy800 Nickel Alloy Steel Flanges

Incoloy800 performance advantages:

1. Excellent corrosion resistance in water-based media with extremely high temperature up to 500℃

2. Excellent resistance to stress corrosion

3. Good processability

The metallographic structure of Incoloy 800:

Incoloy 800 is a face-centered cubic lattice structure.The extremely low carbon content and the increased Ti:C ratio increase the structural stability and maximum resistance to sensitization and intercrystalline corrosion.The low temperature annealing at about 950℃ ensures the fine crystal structure.

Incoloy 800 corrosion resistance:

Incoloy 800 is resistant to many corrosive media.Its high nickel content makes it have good resistance to stress corrosion cracking under water corrosion conditions.The high chromium content makes it more resistant to spot corrosion and crack corrosion cracking.The alloy has good corrosion resistance to nitric acid and organic acid, but limited corrosion resistance in sulfuric acid and hydrochloric acid.In addition to the possibility of spot corrosion in halides, it has good corrosion resistance in oxidizing and non-oxidizing salts.It is also very resistant to corrosion in water, steam and a mixture of steam, air and carbon dioxide.

Corrosion Resistance
For many years prior to its application as a brake tubing material, alloy C70600 had been used in ships, power station condensers and hydraulic lines on tankers, and had displayed excellent resistance to saline conditions. Early tests revealed that copper-nickel has almost the same resistance to burst pressure as steel. In testing, however, when exposed to salt spray over 180 days, steel's burst strength decreases significantly. The copper alloy remains consistently resistant.
For tubes covered with a moist, salty mudpack for six months, brazed steel was severely corroded resulting in perforation of the tubing wall; whereas, only superficial general corrosion was found on the copper-nickel tubing. ISO 4038 and SAE J1047 include a corrosion resistance requirement referring to ISO 3768 asking for a minimum burst pressure of 110 MPa after 96 hours in neutral salt spray. Swedish requirements include a resistance at least equal to 25 of zinc. In all cases alloy C70600 easily exceeds the required corrosion resistance.
