FAQ

What is the main difference between Nickel 200 and Nickel 201 Seamless Tubes?

Nickel 200 and Nickel 201 are made of pure nickel alloys (99% Ni). It is known for its excellent corrosion resistance, thermal and electrical conductivity, and mechanical strength. The main difference lies in carbon content, as Nickel 201 has lower carbon (0.02%) than Nickel 200 (0.15%), making it suitable for higher temperature applications above 315°C. Both are used in the chemical processing, electronics, and food industries and are often supplied as dual-certified Nickel 200/201 for a broader performance range.

Nickel 201 seamless tubes are widely used in industries such as chemical processing, petrochemical, aerospace, power generation, food processing, electronics, marine, and research. Its excellent corrosion resistance, high-temperature strength, and mechanical durability make them ideal for applications like heat exchangers, reactors, piping systems, and precision components exposed to harsh or high-purity environments.

Yes, Nickel 201 seamless tubes are ideal for high-temperature applications above 600°F (300°C) due to their low carbon content, which prevents graphitization and brittleness. Approved by ASME for pressure vessel use up to 1230°F (665°C), they offer excellent strength, durability, and corrosion resistance, even under thermal cycling and harsh conditions.

Yes, Thaida can manufacture Nickel 200 Seamless Tubes as per customer specifications. We offer customized sizes, dimensions, and finishes to meet specific project requirements while ensuring strict adherence to international quality and manufacturing standards.

The composition of 201 tubes varies by material. Stainless Steel 201 contains 16–18% chromium, 5.5–7.5% manganese, and 3.5–5.5% nickel, with small amounts of carbon and other elements. Nickel 201, on the other hand, is a high-purity alloy with about 99% nickel and trace amounts of iron, manganese, silicon, and copper, offering excellent high-temperature stability due to its low carbon content.

Nickel 201 tubes are made from high purity nickel, containing at least 99% and in some cases up to 99.96% pure nickel. The alloy includes very low levels of impurities, with a maximum of 0.02% carbon, 0.40% iron, and 0.35% manganese, in compliance with ASTM standards.

Nickel 201 tubes have a long lifespan owing to their excellent durability, strength, and resistance to corrosion and high temperatures. Actual service life depends on application and operating conditions, but regular cleaning and inspection help maintain performance and prevent premature failure.

Nickel 201 tubes are used in demanding environments such as food and chemical processing, caustic alkali production, and heat-transfer systems. Its excellent corrosion resistance and thermal conductivity make it ideal for heat exchangers, condensers, and pressure vessels. It is also used in electrical components, batteries, pollution control systems, and specialized industrial equipment.
