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 020 (UNS N08020) has excellent corrosion resistance in chemical environments containing sulfuric acid, and useful resistance to environments containing chlorides, nitric acid, and phosphoric acid. Other uses include the production of gasoline, solvents, explosives, inorganic and organic chemicals, pharmaceuticals, and food and synthetic materials. INCOLOY alloy 020 is readily fabricated to produce mixing tanks, heat exchangers, process piping, pickling equipment, pumps, valves, fasteners and fittings. Applications for alloy 020 requiring resistance to aqueous corrosion are essentially the same as those for INCOLOY alloy 825.

A nickel-iron-chromium alloy with additions of copper and molybdenum. It also contains niobium for stabilization against sensitization and resultant intergranular corrosion. The alloy has excellent resistance to general corrosion, pitting and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric and nitric acids. Used for tanks, piping, heat exchangers, pumps, valves and other process equipment.
