Sachiya Steel International is one of the Leading Manufacturer And Exporter for Hastelloy C22 Pipe Fittings, where Cleanliness is critical when welding this nickel – based alloys and care must be used to ensure that sound welds are achieved. Nickel – based alloys such as Hastelloy C22 Compression Pipe Fittings generally exhibit sluggish welding and shallow penetration characteristics, so the possibility of incomplete fusion increases. To prevent the precipitation of secondary phases, rapid cooling in Hastelloy C22 Compression Fittings is required after solution heat annealing.

Rapid air cooling in Hastelloy C22 Ferrule Fittings can also be used on thinner sections thinner, but water quenching is essential on thicker material, and is the preferred method for all thicknesses. Annealing of Hastelloy C22 Double Ferrule Fittings is often performed after cold working operations to restore ductility if the cold work is outer fiber elongation. Full solution annealing at 1900 Degree F – 2150 Degree F is required for Alloy C22 Ferrule Pipe Fittings.

Stress relief temperatures used on Alloy C22 Double Ferrule Pipe Fittings with 1100 Degree F – 1200 Degree F are not effective and may actually promote alloy precipitation detrimental to corrosion resistance. In the majority of corrosive environments, Alloy C22 Compression Pipe Fittings are used in the as – welded condition. Post – weld heat treatment in Alloy C22 Accessories — full solution annealing (1900 Degree F – 2150 Degree F) or stress relief annealing (1100 Degree F – 1200 Degree F) — is usually not required.
