What Are Nickel Alloy Steel Products?
Nickel alloy steel is a family of high-performance materials in which nickel is combined with chromium, molybdenum, cobalt, copper or iron to produce metals that survive conditions ordinary steel simply cannot. The result is exceptional corrosion resistance, retained strength at red heat, and dependable performance under sustained pressure and cyclic load.At Kalpataru Piping, we manufacture, stock and export a complete range of nickel alloy steel products — seamless and welded pipes, plates, sheets, coils, round bars, wires, flanges, forged and buttweld fittings, and fasteners — across more than 40 grades including Nickel 200/201, Alloy 20, Alloy 330, Haynes 25, Haynes 188, Nimonic C263, Waspaloy, MP35N and MP159. Every item is produced to ASTM, ASME, DIN, EN and ISO specifications, backed by an EN 10204 3.1 mill test certificate, and available with third-party inspection on request. Whether you are lining a sulphuric acid reactor, tubing a refinery heat exchanger, or machining turbine hardware to a tight delivery window, our technical team helps you choose the right grade the first time — and ships it from ready stock.

Total-cost insight: Nickel alloy carries a higher purchase price, but in acid or high-temperature service it routinely delivers 3–5× the life of stainless steel — which usually makes it the cheaper material per year of service. We are happy to run that comparison against your actual duty cycle.

FAQs — Nickel Alloy Steel Products
What is nickel alloy steel used for?
Nickel alloy steel is used wherever ordinary steel fails — chemical reactors and acid lines, refinery and offshore piping, gas-turbine hot sections, boiler superheaters, seawater and desalination systems, and hygienic pharmaceutical equipment. Its corrosion resistance and high-temperature strength make it the default choice in aggressive, high-value process environments.
Is nickel alloy stronger than stainless steel?
At room temperature some stainless grades match nickel alloys on tensile strength. The difference shows up under heat: above roughly 600 °C, stainless steel softens rapidly while nickel and cobalt superalloys such as Waspaloy and Haynes 25 retain most of their strength and creep resistance.
What is the difference between Nickel 200 and Nickel 201?
Both are commercially pure nickel. Nickel 201 has a lower carbon content (max 0.02% vs 0.15%), which prevents embrittlement from graphite precipitation. That makes Nickel 201 the correct choice for service above 315 °C, while Nickel 200 is fine for lower-temperature caustic and food-contact duty.
Which nickel alloy is best for high temperature?
For sustained service between 900 °C and 1000 °C, Haynes 25 and Haynes 188 are the strongest options. For furnace and heat-treatment hardware up to about 1150 °C, Alloy 330 offers excellent carburisation resistance at lower cost. Nimonic C263 and Waspaloy suit high-creep turbine components.
Which grade resists sulphuric acid best?
Alloy 20 (Carpenter 20) was developed specifically for sulphuric acid service. Its copper and molybdenum additions resist attack across the full concentration range, and its stabilised composition prevents intergranular corrosion in welded assemblies.
