What Are Incoloy Products?
Incoloy is a family of nickel-iron-chromium superalloys built for the toughest service environments on earth. When ordinary stainless steel begins to scale, pit, or crack, Incoloy keeps performing — resisting oxidation, carburization, chloride stress-corrosion cracking, and sulphuric or phosphoric acid attack at temperatures that would compromise most other metals. That combination of high-temperature strength and broad corrosion resistance is exactly why engineers specify Incoloy for heat exchangers, acid gas piping, furnace components, and pressure vessels.
At Kalpaturu Piping, we manufacture, stock, and export a complete range of Incoloy products — including Incoloy 800, 800H, 800HT, and the versatile Incoloy 825 — in pipes, tubes, plates, sheets, coils, round bars, and fittings. Every product is produced to international standards (ASTM, ASME, DIN, and equivalent GOST/JIS/AFNOR designations) and shipped with full material traceability. Whether you need a single tested coil or a bulk export order, our metallurgists and sales engineers help you match the right grade, temper, and size to your application — delivered on time, at a competitive Incoloy price. Request a quote today and put decades of nickel-alloy sourcing expertise to work for your project.

Frequently Asked Questions (FAQ)
What is Incoloy used for?
Incoloy is used wherever high temperature meets aggressive corrosion — heat exchangers, acid-gas and process piping, furnace components, superheater tubes, and pressure vessels across chemical, petrochemical, oil & gas, and power industries.
What is the difference between Incoloy and Inconel?
Both are nickel-based superalloys, but Incoloy has a nickel-iron-chromium matrix optimized for high-temperature acid and corrosion service at a lower cost, while Inconel is higher in nickel and excels in the most extreme oxidation and heat conditions.
What are the main Incoloy grades?
The most common grades are Incoloy 800 (general purpose), 800H (improved creep strength), 800HT (superior high-temperature stability), and 825 (versatile acid and sour-gas resistance).
Is Incoloy more expensive than stainless steel?
Yes. Because of its high nickel content and superior performance, Incoloy costs more than standard stainless steels — but it delivers longer service life and lower failure risk in severe environments, often reducing total cost of ownership.
