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 276 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. The high chromium, molybdenum and tungsten contents make the alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures.
This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process application in an as welded condition. Alloy 276 is widely used in the most severe environments such as mixed acid chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment, and recovery of sour oil and gas.
