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 22, is a versatile austenitic nickel-chromium-molybdenum-tungsten alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking. The high chromium content provides good resistance to oxidizing media while the molybdenum and tungsten content give good resistance to reducing media. This nickel alloy also has excellent resistance to oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions.
Alloy 22 has resistance to oxidizing acid chlorides, wet chlorine, formic and acetic acids, ferric and cupric chlorides, sea water, brine and many mixed or contaminated chemical solutions, both organic and inorganic. This nickel alloy also offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams. This is beneficial in multi-purpose plants where such “upset” conditions occur frequently.
