Overview:

Krystal is a renowned exporter, manufacturer, stockist, supplier, and stockholder of high-quality Monel Alloy Seamless Tubes. These nickel-copper alloy tubes are celebrated for their excellent corrosion resistance and high strength, making them ideal for marine, chemical, hydrocarbon processing, and oil and gas applications. Monel alloy tubes maintain their strength and toughness across a wide temperature range and offer excellent weldability and ease of fabrication.

Incoloy 8811 (UNS N08811) / Alloy 800HT (1.4876) is a Nickel-Iron-Chromium alloy designed for excellent strength and resistance to oxidation and carburization at high temperatures. The alloy is specifically engineered for superior creep-rupture properties in temperatures up to 982°C (1800°F).

Incoloy 8811 is widely used across industries where high-temperature performance and resistance to thermal and chemical degradation are critical. Typical applications include heat exchangers, process piping, pressure vessels, superheater and reheater tubing, and industrial furnaces. It is also used in petrochemical and power generation equipment, as well as in chemical processing systems that encounter corrosive environments at elevated temperatures.
