Nimonic C263 round bars

NIMONIC® Alloy 263 / 2.4650 / UNS N07263

NIMONIC® alloy 263 (UNS N07263/W. Nr. 2.4650), an air melted nickel-base alloy, was developed by RollsRoyce (1971) Ltd. to provide a sheet material which could be readily fabricated and would offer improved ductility in welded assemblies to replace NIMONIC alloy 80A.


Nimonic C263 round bars suppliers in India.

NIMONIC® Alloy 263 / 2.4650  /  UNS N07263

We are Nimonic C263 round bars suppliers in India. Nimonic Alloy 263 material is deferred under the gas and has been developed to make Nimonic 80A material more flexible and more elastic in places where it is welded. ASTM B463 Nimonic 263 Products can be preferred especially for the parts to be combined with welding, and the usage area of this material, which can be supplied by Ozair trade link, is becoming more widespread. These materials are widely used today.

This alloy has a profound resistance to high-temperature erosion and oxidation. The alloy also boasts of good mechanical properties, is highly resistant to sulfide and chloride stress corrosion cracking while also being resistant to chloride ion stress corrosion cracking and aqueous corrosion. It is used in applications like hot working tools as well. The alloy is used for turbine blades, discs, forgings, ring sections and hot-working tools.

Nimonic C263 alloy Welding ?

Nimonic Alloy 263™ can be welded using the traditional welding methods. Some of the commonly used methods are shielded metal-arc welding, gas metal-arc welding, submerged-arc welding, and gas-tungsten arc welding. It is recommended that matching alloy filler metal should be used. Before the welding process begins, the surface to be welded should be cleaned and should be free from oil, paint or crayon stains.

Heat treatment of Nimonic C263 alloys ? 

Nimonic Alloy 263™ can be solution annealed at 1149°C (2100°F) and rapidly cooled by using the water quench method. It can then be precipitation-hardened at 799°C (1470°F) for 24 h, which can be followed by air cooling.
