Hastelloy C22 Stud Bolts Supplier & Exporter in USA, UAE, Saudi Arabia & Europe
Aurum Overseas manufactures high-performance industrial fastening solutions engineered for highly corrosive environments where chemical resistance, long service life, and structural reliability directly impact operational safety. Our fastening products are widely supplied to chemical processing plants, marine engineering industries, pharmaceutical plants, petrochemical units, refinery systems, and industrial buyers requiring premium corrosion-resistant fastening materials for demanding industrial applications worldwide.
Hastelloy C22 Stud Bolts are widely used in aggressive chemical processing environments where conventional stainless steel fasteners often fail due to acid exposure, oxidizing chemicals, chloride contamination, and corrosive industrial media. Because of their advanced nickel-chromium-molybdenum alloy composition, these fasteners provide exceptional corrosion resistance while maintaining excellent mechanical performance under highly demanding operating conditions.
What are Hastelloy C22 Stud Bolts?
Manufactured for critical industrial fastening applications, Hastelloy C22 Stud Bolts are premium nickel alloy threaded fasteners designed for environments exposed to severe corrosion, acidic chemicals, oxidizing agents, and aggressive process fluids. The alloy is known for its superior resistance against pitting corrosion, crevice corrosion, stress corrosion cracking, and localized chemical attack that often damages conventional fastener materials.
Because of these advanced material properties, Alloy C22 Studs are commonly specified across chemical reactors, pollution control systems, heat exchangers, pressure vessels, pharmaceutical production units, marine systems, and industrial processing plants operating under harsh chemical exposure.
Industrial procurement teams worldwide frequently choose UNS N06022 Fasteners where long-term corrosion protection and fastening reliability are critical for maintaining operational efficiency.

Why Hastelloy C22 is Used in Chemical Processing Industries
Fastening components installed in chemical processing systems must continuously withstand corrosive acids, oxidizing chemicals, chloride contamination, and aggressive industrial fluids that can rapidly degrade ordinary stainless steel fasteners. Material selection therefore becomes critical for maintaining long-term operational safety and reducing unexpected equipment failure.
Hastelloy C22 Studs provide major performance advantages because the alloy offers outstanding resistance against oxidizing acids, reducing chemicals, wet chlorine environments, ferric chloride attack, sulfuric acid exposure, hydrochloric acid systems, and localized corrosion that commonly affects industrial equipment operating under aggressive chemical conditions.
Because of these properties, Nickel Alloy C22 Studs are widely selected for industries where corrosion resistance directly affects equipment durability and process reliability.
C22 Chemical Composition
The alloy chemistry of Hastelloy C22 is specifically engineered to provide exceptional resistance against aggressive chemical attack while maintaining structural integrity under demanding industrial service conditions.
| Element | Composition |
|---|---|
| Nickel (Ni) | Balance |
| Chromium (Cr) | 20 – 22.5% |
| Molybdenum (Mo) | 12.5 – 14.5% |
| Iron (Fe) | 2 – 6% |
| Tungsten (W) | 2.5 – 3.5% |
| Cobalt (Co) | 2.5% Max |
| Manganese (Mn) | 0.5% Max |
| Silicon (Si) | 0.08% Max |
| Carbon (C) | 0.015% Max |
| Vanadium (V) | 0.35% Max |
Understanding the C22 chemical composition is important for industrial buyers because the high nickel, chromium, and molybdenum content directly contributes to the alloy's superior corrosion resistance across highly aggressive chemical environments.

Why Material Selection Matters for Corrosion Resistant Fasteners
Choosing fastening materials for aggressive chemical environments requires buyers to evaluate corrosion resistance performance, chemical compatibility, operating temperature, and long-term service durability. Industrial procurement teams often prioritize alloy performance over initial cost when system reliability directly impacts operational efficiency.
Important technical factors generally include chemical compatibility, resistance against oxidizing acids, chloride corrosion protection, mechanical strength retention, dimensional precision, and compliance with international industrial standards.
Because of its outstanding corrosion-resistant alloy chemistry, UNS N06022 Fasteners remain one of the most reliable fastening materials used across highly corrosive industrial environments worldwide.
Hastelloy C22 vs Hastelloy C276 Stud Bolts
Industrial buyers often compare Hastelloy C22 Stud Bolts and Hastelloy C276 Stud Bolts when selecting premium nickel alloy fastening materials for highly corrosive service environments. Both alloys provide excellent corrosion resistance, but slight differences in alloy chemistry affect performance under certain chemical processing conditions.
| Property | Hastelloy C22 Stud Bolts | Hastelloy C276 Stud Bolts |
|---|---|---|
| Material Grade | UNS N06022 | UNS N10276 |
