Selection Notes
- Use alloy family names only as a starting point; exact grades matter.
- Temperature, media, pressure and fabrication route can change the grade review.
- Share UNS, ASTM or project references whenever available.
Inconel vs Monel vs Hastelloy: Nickel Alloy Selection Guide
Review Inconel, Monel and Hastelloy alloy families for high-temperature, corrosion, marine, chemical and heat exchanger RFQs.
Buyer-focused guidanceRFQ checklistComparison tableNo pricing or stock promises
Direct Answer
Inconel alloys are often reviewed for high-temperature oxidation and strength, Monel alloys for marine and seawater-related corrosion conditions, and Hastelloy alloys for aggressive chemical processing environments. Final selection should follow buyer drawings, standards, service conditions and project requirements.
Buyer Comparison Table
| Option | Common buyer review context | RFQ note |
|---|---|---|
| Inconel | High-temperature, oxidation, heat and pressure service | Share exact grade such as 600, 625 or 718. |
| Monel | Marine, seawater, pump, valve and corrosion service | Share grade such as 400 or K-500. |
| Hastelloy | Chemical, acid and process corrosion service | Share grade such as C-276, C-22 or B-2. |

Frequently Asked Questions
Can Rubinox quote only from a family name such as Inconel?
Rubinox can start RFQ discussion from a family name, but exact grade, form, size and standard are needed for proper review.
Is Monel used only in marine applications?
No. Monel is often reviewed for marine conditions, but final use depends on grade, media and project specification.
Which Hastelloy grade is common for chemical service?
Hastelloy C-276 and C-22 are commonly reviewed, but buyers should share chemical media and project standard.
What details are needed for nickel alloy RFQs?
Share exact grade, UNS, standard, product form, size, quantity, testing and delivery requirement.
Can buyers request documentation?
Buyers can mention MTC, PMI or inspection requirements at enquiry stage where applicable.
