Kanakratna steelage 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. Alloy 201 Pipes and Tubes is similar to Nickel 200 Alloy Pipes and Tubes and is a low carbon modification of the 200 Alloy. UNS N02201 Pipes and Tubes have a low annealed hardness and very low work-hardening rate. Those who use WNR 2.4068 Pipes and Tubes find it desirable in deep drawing, spinning, and coining. We offer these Nickel Alloy 201 products in custom-made shapes and sizes as per the requirements given by our clients, and that too at an affordable and market leading prices.
Nickel 201 alloy is a commercially pure wrought alloy having properties similar to that of nickel 200 alloy, but with a lower carbon content to avoid embrittlement by inter-granular carbon at high temperatures.
It is resistant to acids and alkalis, and dry gases at room temperature. It is also resistant to mineral acids depending on the temperature and concentration of the solution.
