Nickel Alloy Products: Inconel & Hastelloy Manufacturing for Chemical Processing, Energy & Industrial Applications
TiAlloy produces nickel alloy plate, tube, and bar for chemical processing, energy, marine engineering, and general industrial customers. We run our own vacuum induction melting (VIM), vacuum arc remelting (VAR), and electroslag remelting (ESR) – all in house, not at a subcontract mill. Every nickel alloy material shipment leaves the same 30,000+ sqm facility that melted, processed, and finished it.

Manufacturer or Trading Company? How to Verify Before You Order
There’s a fundamental problem for anyone who wants to buy nickel alloy material online: Platform verification badges don’t authenticate manufacturers. Independent market research into sourcing guidance suggests that between 30%-50% of all self-identified “manufacturers” on major B2B marketplaces are actually trading companies; and that a platform’s “Verified Supplier” badge may reflect nothing more than a basic corporate registration status, and doesn’t address production capacity. This gap in understanding is exactly why procurement and engineering teams are advised to verify the presence of a physical production facility-rather than trust a badge-before committing an order to suppliers of nickel alloy material — the same principle behind third-party supplier verification programs used across industrial procurement.
What Real Production Evidence Looks Like
A true mill can state its own melting route (e.g., VIM, VAR, or ESR), and discuss the actual process equipment found on its own floor.
- VIM (vacuum induction melting): crucible melting within a vacuum-sealed steel shell; used to control levels of dissolved oxygen, nitrogen, and hydrogen within the molten metal.
- ESR (electroslag remelting): refines the ingot in a second melting pass, resulting in cleaner material with a more homogeneous microstructure.
- VAR (vacuum arc remelting): an additional consolidation step; often described as VIM, ESR, and VAR occurring sequentially and as discrete process stages, not as interchangeable descriptions of the same process stage.
“When a buyer asks which melting line produced their heat, we can walk them through VIM to final finishing on the same site — a trading company can only forward that question to someone else.”
— TiAlloy production quality teamTiAlloy operates all three of those melting routes in-house, alongside our forging, rolling, heat-treatment, tube production, bar drawing, and finishing lines, all within a single 30,000+ sqm campus. That entire step-by-step sequence is something a distributor cannot share with you. In a more honest comparison, a trading company may present a detailed specification sheet, but only a mill running its own melting lines can take you through the process that produced it.
SYSTEM / SPECIFICATIONS
ISO 9001 vs. Aerospace/Medical-Grade Certification: Know the Difference
The supplied certification package includes ISO 9001:2015 and EN 9100:2018 documentation, with EN 9100 identified as technically equivalent to AS9100D. We will not claim that one certificate automatically covers every end-use program, so match the legal entity, production site, certification scope, and expiry date shown on the certificate to the material and mill documents for the order.
Why AS9100 Is Not the Same Certification
- AS9100 (an aerospace-specific standard published by the International Aerospace Quality Group) is built upon ISO 9001, with approximately 100 additional requirements.
- An AS9100 certification expands on that scope to include things like first-article inspection, traceability for key-characteristics, and prevention of counterfeit materials.
- ISO 13485 is a completely separate medical device quality system; not substitutable with either ISO 9001 or AS9100.
If you’re sourcing materials for an AS9100 (or AS9120)-qualified aerospace/defense program or an ISO 13485-qualified medical device program, please know that ISO 9001 alone is specifically designated as insufficient by the standards committees for those applications. If your program calls for AS9100/AS9120, ISO 13485, or (if applicable) FDA QMSR-documented supply, contact us directly for current certification scope clarity – TiAlloy won’t claim a certification that isn’t applicable, and we’d rather be direct than mislead with an irrelevant “ISO 9001”.
Buyer Advisory: Match the Certification to the Program
Chemical processing, energy, marine, and general industrial buyers should verify ISO 9001 scope against the ordered material. Aerospace/defense and medical-device buyers should also request the program-specific AS9100 or ISO 13485 scope before making a volume commitment.

View Specs →Comparing Nickel Alloy Grades: Composition and Service Environment
Grade, composition and application selection based on your corrosive process, temperatures and pressures – not brand names alone. Below is a screening table using standard designations and typical performance data, compare carefully against your heat and material certification.
| Grade | UNS Number | Primary Alloying | Best-Fit Environment |
|---|---|---|---|
| Inconel 718 | N07718 | Ni-Cr, Nb/Mo, age-hardenable | High-strength, elevated-temp structural service |
| Inconel 625 | N06625 | Ni-Cr-Mo | Chemical processing, marine, high-corrosion service |
| Inconel 600 | N06600 | Ni-Cr | High-temperature oxidation, furnace/heat-treat equipment |
| Hastelloy C-276 | N10276 | Ni-Mo-Cr | Wide-range oxidizing + reducing chemical media |
| Hastelloy-C22 | N06022 | Ni-Cr-Mo-W | Chloride pitting / stress-corrosion-prone service |
Which Nickel Alloy Fits Your Application?
Use this as a preliminary guide, then let us know the precise details of the corrosive process, temperatures, and pressures so we can help select the ideal grade for your application. Choosing the wrong grade for the environment is a common and costly mistake in nickel alloy procurement — a lower-chromium grade specified into a highly oxidizing application, or a general-purpose grade substituted into a chloride-heavy line, both tend to fail early.
| Application | Typical Environment | Recommended Line |
|---|---|---|
| Chemical reactor / heat exchanger | Corrosive process media, moderate-high temp | Inconel 625 / Chemical Processing Solutions |
| Wide-range chemical service | Mixed oxidizing + reducing media | Hastelloy C276 |
| Chloride-heavy / seawater-adjacent | Pitting and stress-corrosion risk | Hastelloy-C22 |
| Furnace / heat-treatment hardware | Sustained high-temperature oxidation | Inconel 600 |
| High-strength structural component | Elevated temperature + mechanical load | Inconel 718 |
| Gas turbine / power generation component | Cyclic high-temperature, oxidizing atmosphere | Inconel 718 / Inconel 625 |
This is the structural reason our decision matrix groups all seven product lines by best-fit service environment rather than by name alone. Unlike marketplaces that lump these grades under one generic “nickel alloy” listing (see the Nickel Institute’s own alloy-family overview for how varied that category actually is), TiAlloy grades each line to the specific environment it is engineered for — so you don’t make the grade-swap mistake procurement teams get wrong most often.
The Honest Material Trade-Off for Seawater Service
The honest version is that titanium is often the better-performing, lower-lifecycle-cost choice for seawater-cooled condensers and marine heat-exchanger tube bundles. It resists chloride pitting without the alloying cost of Hastelloy C22, so review our titanium heat exchanger tube specifications when seawater or brackish water is the actual duty.
Production Base and Ownership of Process
30,000+ m²
Owned production base running melting through finishing in one location
TiAlloy facility scope, cross-referenced against buyer-verification guidance on manufacturer vs. trader status
The decision to bring the whole metal transformation process in-house can be costly if melting capacity isn’t fully used on each individual run, but it results in quality assurance at every stage, not just the end. We have the smelting (including vacuum induction melting), forging, hot and cold rolling, solution annealing, hot isostatic press, heat treating, tube making, bar finishing and plate processing capabilities, all integrated with precision machining. These same lines process titanium, stainless steel, and nickel-based metal alloys alike, with finishing capacity to match.

Buyer Advisory: Cross-Border Shipment Note
Nickel alloy material >60 wt.% Ni falls under the export control classification (ECCN under EAR Part 774). If you are importing into a jurisdiction with parallel controls, confirm ECCN/HS classification with your compliance team before the part leaves the factory — this is an industry-accepted practice, not specific to any one material supplier.
TiAlloy’s service coverage regions currently include Europe, Southeast Asia, the Middle East, South America, and Japan/Korea, with long-term trusted trading relationships established in these regions.
01
How can I tell if a nickel alloy supplier is a real manufacturer, not a trading company?
Ask what melting process they run in-house (VIM, VAR, or ESR), and whether they are able to provide a picture of the tooling and size of plant. A 2026 sourcing-guidance analysis found 30-50% of self-declared “manufacturers” listed on major marketplaces are just traders, and marketplace verification badges are an indicator of commerce, not production – only a picture of the factory can confirm what capabilities are there.
02
Is ISO 9001 certification enough for aerospace or medical-grade nickel alloy programs?
No, ISO 9001 covers the scope of general quality management only. Programs for aerospace/defense call for AS9100; those for medical-devices call for ISO 13485 – always verify scope of your particular product of interest with the supplier.
03
Can I order small or trial quantities of nickel alloy material?
Small-batch / trial orders are a natural area of friction in this industry — engineers sourcing test quantities of nickel and superalloy material often find it difficult to identify suppliers willing to help. Our pre-sale quick-quote process is designed to allow for a simple confirmation of what order quantities are feasible; make sure you ask directly for your target order size.
04
What is the difference between VIM, VAR, and ESR melting?
They are sequential, distinct refining steps, not equivalent terms, and each of them remedies a different problem area within the ingot. VIM melts the alloy within a vacuum-sealed crucible to control dissolved oxygen, nitrogen, and hydrogen; ESR remelts that ingot through a resistive slag layer to strip inclusions and modify the internal structure; VAR further consolidates the ingot under vacuum arc conditions to reduce porosity and center-line segregation before it transitions to forging. Numbered patents for refining processes list them sequentially in the same specific order — for example, a VIM remelt followed by an ESR remelt followed by vacuum arc remelt — precisely because each stage improves a different aspect of the alloy’s cleanliness, homogeneity, and mechanical strength that subsequent stages do not address alone.
