Superalloys – Engineered to Perform at Extreme Temperatures
High-performance nickel, cobalt and iron-based superalloys designed for high-temperature, high-stress, and corrosive industrial environments. Trusted by aerospace, energy and chemical industries.
What Are Superalloys?
Superalloys, also known as high-performance alloys, are a class of metallic materials designed to:
Maintain strength and surface stability at temperatures above 600°C (1110°F)
Resist oxidation, creep, fatigue and corrosion under stress
Serve in aerospace, turbine engines, nuclear, and chemical plants
Superalloy Categories:
Type | Base Metal | Typical Grades | Applications |
---|---|---|---|
Nickel-based | Ni | Inconel 625, 718, X750 | Turbines, heat exchangers |
Cobalt-based | Co | Haynes 25, L605, 188 | Jet engines, combustors |
Iron-based | Fe | A-286, Incoloy 800/825 | Petrochemicals, heat tubes |
These alloys combine solid solution strengthening, precipitation hardening, and oxidation resistance to achieve unmatched reliability in harsh environments.

Frequently Asked Questions
Q1: Which superalloy is best for 700°C continuous service?
A:
Inconel 625 or 617 are ideal due to high strength and oxidation resistance at 650–800°C range.
Q2: Can I get heat treatment per AMS specifications?
A:
Yes, we support AMS 5662, 5663 (for Inconel 718) and other heat treatment cycles on request.
Q3: Do you offer non-standard bar sizes?
A:
We offer forged or rolled bars in custom diameters and lengths with tight tolerances.
Q4: Can you machine complex turbine shapes?
A:
Yes, CNC and EDM services are available for superalloy components per drawing.
Q5: What is the lead time for superalloy plate or forged parts?
A:
Stock items: 5–7 days. Forged or heat-treated: 10–25 days based on grade and complexity.
