Material Overview
What Are Heat Resistant Alloys?
Heat resistant alloys are nickel-iron-chromium compositions engineered to maintain mechanical strength, dimensional stability, and oxidation resistance under prolonged exposure to elevated temperatures, often above 700°C. Unlike standard steels, which lose strength and oxidise rapidly at high temperatures, these alloys retain their properties through sustained thermal exposure and cyclic heating conditions.
The combination of chromium for oxidation resistance, nickel for structural stability, and additional elements such as aluminium, molybdenum, and copper enables these alloys to perform where conventional materials fail. This makes them essential across petrochemical, power generation, chemical processing, and industrial furnace environments.
ABCOM trades and processes heat resistant alloy scrap and primary forms, including reformer tube and furnace component material. Our technical expertise in alloy identification and grading ensures that material entering downstream supply chains meets the compositional requirements of foundries and re-melters.

End Markets
Industries & Applications
Petrochemical & Reformers
Steam methane reformer tubes and furnace components operating continuously at extreme temperatures demand the creep resistance and oxidation stability of grades such as INCO 800 and reformer-grade material.
Chemical Processing
Heat exchangers, pressure vessels, and piping handling aggressive media at elevated temperatures require nickel-iron-chromium alloys that resist both oxidation and corrosive attack.
Power Generation
Furnace muffles, radiant tubes, and heat treating equipment in power plants rely on heat resistant alloys to maintain structural integrity under sustained thermal load.
Aerospace & Industrial Furnaces
Fixtures and structural components in industrial furnaces and aerospace heat treatment require thermal stability across hundreds of thermal cycles, where grades such as INCO 601 are standard.
Electronics
Controlled thermal expansion materials such as Invar are used in precision instruments, optical benches, and electronic assemblies where dimensional stability is critical.
Food Processing
High-temperature processing lines in food manufacturing require heat-resistant equipment that maintains mechanical integrity under sustained elevated operating conditions.
Material Categories
Grades We Supply
INCO 600 & 601
Nickel-chromium alloys offering excellent resistance to oxidizing and reducing environments across a wide temperature range. INCO 601 adds aluminium to the base composition, which significantly enhances high-temperature oxidation resistance, making it the preferred grade for furnace fixtures, heat treating baskets, and components exposed to cyclic heating. Both grades are widely recovered from decommissioned furnace and heat treating equipment.
INCO 925 & 825
Nickel-iron-chromium alloys with molybdenum and copper additions, providing resistance to both oxidizing and reducing acids alongside high-temperature stability. INCO 825 is extensively used in chemical processing, heat exchangers, and acid production environments. These grades are recovered from chemical plant and petrochemical decommissioning streams.
INCO 800 & 904L
INCO 800 is a workhorse heat-resistant alloy used extensively in reformer tubes and furnace components, valued for its strength and oxidation resistance at sustained high temperatures. 904L is a high-alloy austenitic stainless grade offering exceptional resistance to strong acids and chloride environments. Both are significant scrap streams from petrochemical and industrial plant decommissioning.
Nim 80A & Reformer Grades
Nimonic 80A is a precipitation-hardened nickel alloy developed for high-temperature fasteners, springs, and components operating at elevated temperatures where creep resistance is required. Reformer-grade material is specified for steam methane reforming tube applications, a primary focus of ABCOM's heat resistant alloy scrap recovery operations given the high nickel and chromium content.
Invar & Nickel Screen
Invar is a nickel-iron alloy with a near-zero coefficient of thermal expansion, used in precision instruments, scientific equipment, composite tooling moulds, and electronic assemblies where dimensional stability across temperature ranges is critical. Nickel screen material is recovered from industrial high-temperature screening and filtration applications.
Others
ABCOM handles additional heat resistant alloy grades and forms on inquiry, including less common nickel-chromium and nickel-iron-chromium compositions recovered from specialist industrial applications. Contact our team with details of material available or required.
Our Capabilities
Processing & Recycling
ABCOM processes heat resistant alloy scrap from petrochemical, power generation, and industrial sources. Reformer tube and furnace component scrap recovery is a significant focus of our operations. These materials contain high concentrations of nickel and chromium that carry strong recycled value when properly sorted and graded.
Incoming material is sorted and graded by alloy family. Nickel-chromium grades such as INCO 600, nickel-iron-chromium grades such as INCO 800, and controlled expansion alloys such as Invar are processed separately to maintain compositional integrity across each stream. Reformer-grade and furnace component scrap is evaluated based on alloy specification and condition before classification.
Quality control and traceability are applied at each stage of the process. Material is documented from origin through to dispatch, supporting the compliance requirements of our manufacturing customers. Learn more about our operations on the about page.

Common Questions
Frequently Asked Questions
What are heat resistant alloys used for?
Heat resistant alloys are used in applications that require sustained performance at elevated temperatures, typically above 700°C. Common uses include reformer tubes in petrochemical plants, furnace muffles and radiant tubes, heat exchangers, pressure vessels, and high-temperature fixtures in aerospace and industrial furnace environments.
What is the difference between INCO 600 and INCO 601?
Both are nickel-chromium alloys offering strong oxidation and corrosion resistance. INCO 601 adds aluminium to the composition, which significantly enhances its resistance to high-temperature oxidation, making it the preferred choice for furnace fixtures, heat treating baskets, and components exposed to cyclic heating above 1000°C. INCO 600 is suited to a broad range of high-temperature and corrosive environments where aluminium addition is not required.
Why is reformer tube scrap valuable?
Reformer tubes are manufactured from high-alloy nickel-iron-chromium compositions (grades such as INCO 800 and similar reformer-grade materials) to withstand continuous operation at extreme temperatures in steam methane reforming. When decommissioned, the scrap retains substantial concentrations of nickel, chromium, and iron that can be recovered and re-entered into alloy supply chains, making reformer tube scrap a consistently valuable secondary material stream.
What industries use heat resistant alloys?
Primary industries include petrochemical and refining (reformer tubes, furnace components), power generation (furnace muffles, radiant tubes), chemical processing (heat exchangers, pressure vessels), aerospace (high-temperature fixtures), electronics and precision instruments (controlled expansion alloys such as Invar), and food processing (high-temperature equipment).
What is Invar used for?
Invar is a nickel-iron alloy with a near-zero coefficient of thermal expansion, making it uniquely suited to applications where dimensional stability across temperature ranges is critical. It is used in precision instruments, optical equipment, scientific measurement devices, composite tooling moulds, and electronic components where thermal expansion must be minimised.
