Kanakratna steelage is a renowned exporter,
manufacturer, stockist, supplier, and stockholder of high-quality Inconel
Alloy Seamless Tubes. These nickel-chromium alloy tubes are celebrated for
their exceptional resistance to oxidation and corrosion at high
temperatures, making them ideal for aerospace, chemical processing, power
generation, and oil and gas applications. Inconel alloy tubes maintain their
strength and stability across a wide temperature range and offer excellent
weldability and ease of fabrication, ensuring reliable performance in the
most demanding environments.
Alloy 825 (UNS N08825) is an austenitic
nickel-iron-chromium alloy with additions of molybdenum, copper and
titanium. It was developed to provide exceptional corrosion resistance in
both oxidizing and reducing environments. The alloy is resistant to chloride
stress-corrosion cracking and pitting. The addition of titanium stabilizes
Alloy 825 against sensitization in the as-welded condition making the alloy
resistant to intergranular attack after exposure to temperatures in a range
that would sensitize unstabilized stainless steels. The fabrication of Alloy
825 is typical of nickel-base alloys, with material being readily formable
and weldable by a variety of techniques
