ARK Stainless Inc. is a manufacturer, supplier and exporter of Nickel 200 and Nickel 201 Forged Fittings in India. We manufacture threaded and socket weld forged fittings for piping systems used in chemical processing, caustic handling, power generation, food processing and other industrial applications where corrosion resistance and material purity are important requirements.
Nickel 200 and Nickel 201 are commercially pure nickel grades known for their resistance to alkalis, good thermal conductivity and stable performance across a wide temperature range. Nickel 200 is commonly used for general corrosive service, while Nickel 201, with lower carbon content, is often preferred for elevated-temperature applications where resistance to graphitisation is required.
Our range includes forged elbows, tees, couplings, unions, caps, plugs, bushings and pipe nipples manufactured in accordance with ASTM B564 / ASME SB564 and applicable ASME dimensional standards. These forged fittings are supplied for industrial piping systems requiring dependable performance in corrosive and temperature-sensitive service conditions.

ARK Stainless Inc. manufactures and supplies Nickel 200 and Nickel 201 forged fittings for corrosive process piping systems used in chemical processing, caustic service, food processing and heat exchanger applications. Our range includes socket weld and threaded elbows, tees, couplings, unions, caps, plugs, bushings and pipe nipples manufactured in accordance with ASTM B564, ASME SB564 and ASME B16.11 requirements.
Nickel forged fittings are generally selected for piping systems handling caustic alkalis, process chemicals and high-purity media where commercially pure nickel offers better resistance than many stainless steel grades. Nickel 200 is commonly used for general corrosive service, while Nickel 201 is often preferred for elevated-temperature applications due to its lower carbon content. These forged fittings are used in smaller bore piping systems for branch connections, flow direction changes, end closures and threaded or welded connections in process lines.
Nickel 200 Forged Fittings are manufactured from commercially pure wrought nickel with good resistance to caustic alkalis and a range of corrosive reducing environments. These fittings are widely used in chemical processing plants, food handling systems, caustic soda service, synthetic fibre plants and process lines where nickel is specified for corrosion resistance and product purity.
Nickel 200 forged fittings also offer good thermal and electrical conductivity along with useful mechanical strength for industrial piping systems. In forged fitting form, the grade is commonly supplied as elbows, tees, couplings, unions, plugs and bushings for threaded and socket weld piping connections.
Nickel 201 Forged Fittings are similar to Nickel 200 but with lower carbon content, which makes the grade more suitable for elevated temperature service. This lower carbon level helps reduce the risk of embrittlement or graphitisation in certain temperature ranges, which is why Nickel 201 is often selected for hot caustic service, heat exchangers, process vessels and high-temperature chemical processing systems.
Nickel 201 forged fittings are used where the corrosion resistance of pure nickel is required along with better stability at higher operating temperatures. These fittings are supplied in socket weld and threaded forms for use in process piping, plant utility systems and specialised nickel alloy installations.
The main difference between Nickel 200 and Nickel 201 forged fittings is carbon content. Nickel 201 is the lower-carbon version of Nickel 200 and is generally preferred for elevated temperature applications where resistance to graphitisation is important. Nickel 200 is commonly used in general corrosive and caustic service, while Nickel 201 is more often specified when the piping system operates at higher temperatures.
Both grades offer good corrosion resistance in caustic environments and are available in similar forged fitting forms such as elbows, tees, couplings, unions and pipe nipples. Final grade selection usually depends on process media, operating temperature and project material specifications.
Nickel forged fittings are used in piping systems where resistance to caustic alkalis, corrosive chemicals and high-purity process media is important. These fittings are commonly supplied for:
We manufacture Nickel 200 / 201 forged fittings in a range of standard forged fitting forms for industrial piping systems. Our range typically includes:
Nickel 200 and Nickel 201 forged fittings offer good ductility, useful mechanical strength and stable performance in corrosive service conditions. While these grades are not selected primarily for very high strength in the way some nickel alloys are, they are widely used where corrosion resistance, fabricability and service reliability are more important than extreme pressure performance.
Nickel forged fittings also retain good toughness and are suitable for fabrication into threaded and socket weld forms used in process piping systems. Mechanical properties may vary according to grade, product form and heat treatment condition.
We manufacture Nickel forged fittings according to recognised ASTM and ASME specifications for forged piping components. Common manufacturing and dimensional standards include:
These fittings are manufactured for use in high-integrity piping systems where material compliance and dimensional accuracy are important.
Nickel 200 and Nickel 201 forged fittings are available in pressure classes commonly used for forged piping components under ASME B16.11 requirements. Depending on fitting type and end connection, forged fittings can be supplied in:
Threaded forged fittings are generally supplied in Class 2000#, 3000# and 6000#, while socket weld forged fittings are commonly available in Class 3000#, 6000# and 9000#. The final pressure class is selected according to the design pressure, temperature and service conditions of the piping system.
Nickel forged fittings are available in both socket weld and threaded configurations for process piping and utility systems. Socket weld fittings are commonly used in permanently welded piping installations where a compact high-pressure connection is required. Threaded forged fittings are often selected for smaller bore piping, instrument lines and systems where easier removal, maintenance or replacement may be required during service.
We supply Nickel 200 and Nickel 201 forged fittings in threaded forms such as NPT, BSP and BSPT, depending on project requirements and piping standards.
Nickel forged fittings are commonly used in industries where piping systems handle corrosive fluids, caustic compounds or process media that demand the use of commercially pure nickel. Typical industries include:
These industries often specify Nickel 200 or Nickel 201 where corrosion resistance and material purity are important to process performance.
Nickel forged fittings are often selected for corrosive process piping because they offer a combination of chemical resistance, fabrication suitability and service reliability. Nickel 200 and Nickel 201 perform well in caustic alkali environments and are used in process systems where many conventional materials may not be preferred.
Another advantage is the availability of these grades in standard forged fitting forms such as elbows, tees, couplings and unions for threaded and socket weld piping layouts. This makes it easier to build complete nickel alloy piping systems for chemical plants, food processing facilities and high-purity process applications.
