Overview:

Krystal is a renowned exporter, manufacturer, stockist, supplier, and stockholder of high-quality Nickel Alloy Seamless Tubes. These tubes are celebrated for their excellent corrosion resistance, high-temperature strength, and durability, making them ideal for applications in aerospace, chemical processing, power generation, and marine industries. Nickel alloy tubes maintain their mechanical properties across a wide temperature range, ensuring consistent performance in demanding environments. Additionally, they offer superb weldability and ease of fabrication, making them a reliable choice for a variety of critical applications.

INCOLOY alloy 28 (UNS N08028) is a highly corrosion-resistant austenitic alloy offering resistance to a variety of media. The alloy resists attack in reducing media due to its contents of nickel, copper and molybdenum and is resistant to oxidizing species due to its high level of chromium. Alloy 28 offers resistance to general, localized and stress-induced corrosion by chlorides and hydrogen sulfides. Thus, it is widely used in oilfield applications. Tubes are cold worked to high levels of strength for downhole service in deep sour gas wells. With its excellent combination of strength and corrosion resistance, alloy 28 also finds applications in the process industries. It is especially useful for handling phosphoric acid. Due to its resistance to chlorides, alloy 28 tubes may be used in the marine industry for seawater-cooled heat exchangers.
