Nickel Alloy 200 / 201 Pipe & Tube Manufacturer, Supplier, and Stockists in India

Samay Steel and Engineering Co. is a prominent entity in Mumbai, India, known for its expertise as a manufacturer, stockist, and exporter of a comprehensive range of steel products, including high-quality Nickel Alloy 200 / 201 Pipe & Tube. With a strong commitment to quality and a broad distribution network, they cater to diverse industrial requirements across the globe. Their specialization in nickel alloys, among other materials, highlights their capability to deliver products suitable for demanding environments.

Nickel Alloy 200 and Nickel Alloy 201 are commercially pure wrought nickel materials, primarily differing in their carbon content. Nickel 200 has a maximum carbon content of 0.15%, while Nickel 201 has a lower carbon content of 0.02% max. This lower carbon in Nickel 201 is crucial for applications involving exposure to temperatures above 315°C (600°F), as it prevents graphitization and subsequent embrittlement. Both alloys exhibit excellent mechanical properties, including high ductility and malleability, along with good thermal and electrical conductivity.

A key characteristic of Nickel Alloy 200 / 201 Pipe & Tube is their exceptional corrosion resistance. They demonstrate superior resistance to various reducing chemicals and are unexcelled in their resistance to caustic alkalis, even in high concentrations and molten states. This makes them ideal for maintaining product purity in industries handling foods, synthetic fibers, and caustic solutions. While excelling in reducing environments, they can also perform well in oxidizing conditions where a passive oxide film can form.

These pipes and tubes find widespread application in a multitude of industries due to their robust properties. Common sectors include chemical and petrochemical processing, oil and gas, power generation, pharmaceuticals, food processing, and marine/offshore engineering. Specific applications range from caustic evaporators and chemical shipping drums to heat exchangers, electronic components, and even aerospace and missile parts. Their ability to withstand thermal cycling and shock further enhances their utility in high-temperature settings.
