Inconel Coil Manufacturer, Supplier and Exporter of ASTM B168 Coils
Inconel coils are nickel-chromium alloy coils built to hold their shape and strength where standard steel gives out. High temperature, corrosive chemicals and sustained mechanical load do not compromise their structural integrity. Nandini Steel offers Inconel coils in accordance with ASTM and ASME specifications with ISO 9001:2015 certification throughout sourcing, testing and dispatch. All coils are subjected to dimensional verifications and chemical analysis tests prior to shipment. Customers in the aerospace, oil and gas, and chemical processing industries use us to manage material traceability and full documentation of each shipment. Custom sizing refers to particular thickness, width and coil weight; there’s no minimum order quantity to inhibit smaller projects. We are a manufacturer of Inconel coils, stocking a variety of grades, maintaining short lead times even for emergency orders.
Inconel Coil Manufacturer and Stockist of Hot Rolled Nickel Alloy Coils
Key Features of Inconel Coils
-
High-Temperature Resistance
Inconel coils sustain continuous service temperatures up to 1000°C without losing tensile strength. That performance puts them ahead of standard 300-series stainless steel in furnace linings and turbine housings.
-
Superior Corrosion Resistance
High nickel and chromium content protects against pitting and stress corrosion cracking. In marine and chemical processing environments, where conventional alloys degrade within months, Inconel coils continue performing.
-
Oxidation and Creep Resistance
Scaling resistance holds up above 900°C, and dimensional stability stays consistent under prolonged thermal load. Gas turbine components depend on exactly this property.
-
Exceptional Mechanical Strength
Tensile strength ranges from 690 MPa to 1035 MPa depending on grade. This gives Inconel coils a clear strength advantage over conventional stainless steel in load-bearing applications.
-
Weldability Without Trade-Offs
TIG, MIG and resistance welding all work on Inconel coils without weakening corrosion resistance at the weld zone, cutting time spent on post-weld treatment.
-
Multi-Purpose Applications
Aerospace manufacturers, nuclear plant operators, heat exchanger fabricators and chemical processing units specify Inconel coils for components exposed to extreme service conditions.
Different Grades & Industrial Applications
Nandini Steel supplies four primary grades of Inconel coils, each suited to a distinct operating condition.
- Inconel 600: Resists oxidation and corrosion at high temperatures. Furnace components, chemical processing equipment and nuclear reactor internals rely on this grade.
- Inconel 625: Combines high strength with resistance to pitting and crevice corrosion. Aerospace ducting, marine hardware and chemical processing lines use it in place of heavier alloys.
- Inconel 718: Retains mechanical strength from cryogenic temperatures up to 700°C. Jet engine components, gas turbine parts and rocket engine assemblies are built from this grade.
- Inconel 825: Withstands sulphuric, phosphoric and organic acids. Piping systems, heat exchangers and pollution control equipment across chemical plants use it for acid exposure.
As an Inconel coil supplier stocking all four grades, we match project specifications without extended procurement delays.
Packaging, Testing & Delivery
Every Inconel coil undergoes ultrasonic, mechanical testing and chemical composition analysis before shipping. These checks ensure that the dimensions are correct, the alloy composition is as per ASTM standards and identifies any defect that can be encountered in the later stages of the performance. ISO 9001:2015 certification regulates: from raw material inspection to final shipping document preparation.
Packaging protects the coil through transit. A moisture-proof film is wrapped around each coil initially, and then the coil is placed on wooden pallets that are designed to hold the coil weight. Shrink wrap and steel banding are used to hold the load together and the shipment labels indicate the grade, batch number and dimensions,to identify upon arrival. Bulk orders move in specialised transport containers that minimise the damage from freight handling on long distance shipments.

Inconel Coil Chemical Composition (%)
As a trusted Inconel coil manufacturer, we provide Inconel coils that obtain their corrosion resistance from a nickel-chromium base. Iron, molybdenum, niobium, and titanium are added in different proportions across grades, and that changes how each one holds up under heat, acid, or chloride exposure. The table below lists composition limits for the grades supplied, ranging from Inconel 600 through Inconel 825.

Equivalent Grades for Inconel Coil
Cross-referencing standards matters when a project specification requires a DIN or Werkstoff number instead of a UNS code. This table maps each Inconel coil grade against its equivalent designations, which helps avoid ordering errors when drawings cite different standards. Grades with overlapping compositions, like 800H and 800HT, still carry distinct carbon limits worth checking.

FAQs
What are Inconel coils used for?
Inconel coils serve high-temperature and corrosive-environment applications, including aerospace components, gas turbines, heat exchangers, chemical processing equipment and nuclear reactor parts.
How are Inconel coils tested?
Each coil undergoes ultrasonic testing, mechanical property testing and chemical composition analysis to confirm compliance with ASTM and ASME specifications before dispatch.
Do you supply custom thickness and width Inconel coils?
Yes. Nandini Steel cuts coils to specific thickness and width tolerances based on project drawings, and no fixed minimum order quantity applies to custom sizes.
How can I order Inconel coils?
Send your required grade, thickness, width and coil weight to our sales team through the contact form or by phone. We confirm stock availability and issue a quote within one business day.
Can Inconel coils be supplied in customized sizes?
Coil weight, inner diameter and outer diameter can all be adjusted to match your handling equipment and processing line requirements, beyond thickness and width customization alone.
How do I select the right Inconel coil grade for my application?
Match the grade to your primary stress factor: Inconel 600 for oxidation resistance, 625 for a strength-to-corrosion balance, 718 for high mechanical loads, or 825 for acid exposure. Our technical team can confirm the right fit based on your operating temperature and chemical exposure data.
