Incoloy Sheets
High-Temperature, Corrosion-Resistant Alloy Sheets for Demanding Industrial Applications
RSD offers premium-grade Incoloy Sheets, designed for durability in high-temperature and corrosive environments. Composed primarily of nickel, iron, and chromium with additional elements depending on the grade. Incoloy is engineered for structural stability and oxidation resistance in extreme industrial conditions.
From heat exchangers and furnace trays to power plant tubing and pollution control equipment, Incoloy Sheets deliver unmatched performance in industries where other materials degrade. Their metallurgical structure makes them suitable for continuous service at elevated temperatures without sacrificing strength or corrosion resistance.

Key Features & Benefits
Outstanding Oxidation & Carburization Resistance:
Incoloy resists surface scaling and degradation in high-temperature conditions, especially in furnace atmospheres, making it ideal for continuous heat exposure.
Strong Mechanical Properties at Elevated Temperatures:
Maintains tensile and rupture strength even when exposed to temperatures above 1000°C, especially in the 800H/800HT variants.
Corrosion Resistance in Acidic & Aqueous Media:
Incoloy 825, in particular, shows strong resistance to sulfuric acid, phosphoric acid, and seawater, enabling use in chemical and marine sectors.
Good Fabricability & Weldability:
Incoloy Sheets are easily formed and welded using standard techniques, with minimal risk of sensitization or cracking.
Common Applications
Incoloy Sheets are widely used in:
- Thermal Processing Equipment:
Furnace trays, baskets, hangers, and radiant tubes where heat resistance is critical. - Power Generation & Nuclear:
Steam generator tubing, superheaters, and heat exchangers in nuclear and fossil-fuel power plants. - Chemical & Petrochemical Industry:
Reactors, acid tanks, evaporators, and heat exchangers exposed to mixed chemical flows. - Marine Applications:
Incoloy 825 is used in seawater piping systems, offshore structural components, and desalination plants. - Pollution Control:
Stack liners, ductwork, and scrubbers in flue gas desulfurization units.
