Hastelloy C-22 (UNS N06022) Super Corrosion Resistant Compound

Zhonggongte Metallurgical provides premium hastelloy c22 pipe and hastelloy C22 alloy tube products designed for the most aggressive and demanding applications in chemical processing, environmental protection, high-purity fluid systems, and metallurgical industries.

Hastelloy C-22 (UNS N06022) is a nickel-chromium-molybdenum-tungsten super-corrosion-resistant alloy with extremely stable chemical composition, superior mechanical properties, and excellent resistance to both oxidizing and reducing media.

These features make our tubing and piping components ideal for long-term stability in harsh corrosion environments.

All technical foundations are based on original Haynes factory specifications, heat-treatment standards, mechanical performance benchmarks, and strict quality control protocols,ensuring that every hastelloy c22 pipe and hastelloy C22 alloy tube meets or exceeds the highest global standards.

The essential connection between brand and alloy

Hastelloy C-22 is a registered trademark of Haynes International Inc. of the United States for the UNS N06022 alloy. It has the same chemical composition and core performance as Inconel C22 (Special Metals brand), both belonging to the "nickel-chromium-molybdenum-tungsten super corrosion-resistant alloy". However, Haynes provides more detailed original factory process standards, quality control procedures and brand-specific technical support. The following content is based on Haynes original factory data (latest version in 2025).

Haynes Original Factory Core Technical Specifications

1. Chemical composition (Haynes QQ-N-286 compliant version)

2. Original manufacturer mechanical properties (solution state, Haynes TM-1001 standard)

3. Original factory heat treatment process (Haynes HT-2005 specification)

Haynes Original Product Form and Specification Tolerances

1. Core product (Haynes original model)

2. Original factory surface quality standard (Haynes SQ-100)

Haynes Original Manufacturer Recommended Application Cases (2023-2025)

1. Chemical Industry (Certification Case)

• Chlorobenzene production reactor for chemical plants : Made of Haynes 22® sheet (20mm thick) welded together, resistant to corrosion from a mixture of hydrochloric acid and chlorine at 120℃. On-site welding technical support is provided by the original manufacturer. Service life is guaranteed to be ≥20 years.

• The leaching tank of a certain hydrometallurgical nickel smelting project uses Haynes 22® seamless tubing (OD 159mm × wall thickness 8mm) to transport sulfuric acid leaching solution containing Cl⁻ (30000ppm), and the original manufacturer provides a corrosion resistance life assessment report.

2. Environmental Protection Sector (FGD System Dedicated Solution)

• Flue gas desulfurization tower for coal-fired power plants : Haynes 22® welded pipe (OD 108mm × wall thickness 5mm) is used as the spray pipe to replace the original 316L stainless steel, solving the problem of crevice corrosion. The original manufacturer provides a salt spray test report (1500h rust-free).

• Waste incineration plant leachate treatment equipment : uses Haynes 22® bar stock to process pump impellers, which are resistant to high concentrations of Cl⁻ (50000ppm) + organic acid corrosion, and the original manufacturer provides material traceability certificates.

3. Semiconductor field (ultra-high purity applications)

• The etching solution delivery system of a TSMC wafer fab uses Haynes 22® seamless tubing (OD 25mm × wall thickness 3mm), with electropolished inner walls (Ra≤0.2μm), and the original manufacturer provides a metal ion dissolution test report (≤1ppb), conforming to SEMI F57 standards.

Haynes Original Packaging and Certification Standards

1. Original factory packaging (dedicated anti-corrosion solution)

2. Original manufacturer certification documents (Haynes proprietary format)

• Core document : Haynes Certificate of Compliance (CoC), containing:

◦ Furnace number, heat treatment batch number, and product traceability code (unique identifier);

◦ Furnace-by-furnace chemical composition analysis (ICP-OES data);

◦ Mechanical performance test report (including original manufacturer's laboratory number);

◦ Corrosion resistance test report (ASTM G48/G28 original data);

• Special Certification :

◦ Aerospace: NADCAP heat treatment certification (Haynes laboratory number HL-2025);

◦ Nuclear power sector: ASME BPVC III certification (compliant with NB-23 standard);

◦ Food/Pharmaceutical: FDA approved (21 CFR Part 175.300).

Key Points for Original Manufacturer Procurement and Verification

1. Authenticity verification : Check production information through the official website (to avoid counterfeit products);

2. Technical support : Provides direct contact with original equipment manufacturer (OEM) technical engineers (such as welding process optimization and corrosion life assessment).

3.Batch requirements : It is recommended to use products from the same furnace number for key equipment to ensure uniform performance; 

4.After-sales guarantee : Sign a quality assurance agreement (usually a 10-year corrosion warranty for normal operating.
