In today’s industries—where extreme temperatures, corrosive environments, and high mechanical stress are the norm—material selection becomes a critical factor in performance and safety. Hastelloy, a family of high-performance nickel-based alloys, is among the most trusted materials used in chemical processing, aerospace, marine engineering, and power generation.
At Hangnie Super Alloys Co., Ltd., we specialize in the custom fabrication of Hastelloy components, offering advanced welding, forming, and machining services tailored to meet exacting client requirements across the globe.
Why Hastelloy? A Scientific Approach to Corrosion Resistance
Hastelloy alloys, particularly grades like C-276, C-22, B-2, and X, are renowned for their superior corrosion resistance, especially in harsh environments containing chlorides, acids, and oxidizing agents. With a foundation in nickel, molybdenum, chromium, and iron, Hastelloy exhibits:
Outstanding resistance to localized corrosion (pitting and crevice)
High performance in both oxidizing and reducing conditions
Excellent weldability and formability
These characteristics make it a go-to solution for demanding industries where failure is not an option.
Precision Hastelloy Fabrication Techniques
Fabricating Hastelloy is not a simple task. It requires a deep understanding of metallurgical behavior, thermal sensitivity, and mechanical properties. At Hangnie Super Alloys, our Hastelloy fabricators follow proven methods supported by years of engineering experience:
Cutting & Machining
Due to its work-hardening nature, Hastelloy must be cut using carbide tools with low cutting speeds and high feed rates. We use CNC machining and specialized coolants to minimize surface hardening and achieve fine tolerances.
Forming & Forging
Both hot and cold forming are possible, but controlled conditions are essential. Our technicians monitor forming temperatures precisely to avoid stress cracking and preserve uniform microstructure in bars, flanges, and forged components.
Custom Alloy Welding
One of the most critical aspects of Hastelloy fabrication is welding. At Hangnie Super Alloys, we use:
GTAW (TIG) and GMAW (MIG) for clean, low-contamination welds
Matching filler metals to ensure corrosion resistance remains intact
Post-weld heat treatment (PWHT) and pickling to restore mechanical and corrosion properties
This results in welds that are as strong and corrosion-resistant as the base metal—a must for pressure vessels and piping systems in chemical and marine environments.
Applications of Custom Hastelloy Components
Our Hastelloy parts are used in:
Chemical reactors, scrubbers, and acid handling systems
Gas turbine engines and aerospace exhaust assemblies
Desalination plants and marine exhaust systemsPharmaceutical reactors and food-grade equipment
With our custom alloy welding and fabrication solutions, we support mission-critical industries where durability and reliability are paramount.
