Hastelloy C-22 Plate for Marine and Seawater Corrosion Protection
Our Hastelloy C-22 plates are the ultimate solution for marine and seawater corrosion protection. Made from a nickel-chromium-molybdenum alloy, these plates are designed to tackle the brutal corrosion of seawater, chlorides, and harsh marine conditions. They’re perfect for ship components, offshore platforms, and desalination systems. Easy to weld, cut, and form, they resist pitting, crevice corrosion, and stress corrosion cracking. Whether it’s sulfuric acid or oxidizing media, our plates keep your marine equipment in top shape, no matter the challenge.
The marine industry is riding a wave of growth, with demand for corrosion-resistant materials surging. Stricter environmental regulations and the expansion of offshore oil and gas exploration are pushing the need for durable plates. Desalination plants and coastal power facilities are booming, especially in emerging markets, driving demand for high-performance alloys. Trends show a shift toward materials that offer longer lifespans and lower maintenance costs in harsh marine environments. Our Hastelloy C-22 plates are leading the charge, delivering reliability and durability in a competitive market.
Parameter | Hastelloy C-22 Plates | Other Nickel Alloys | Stainless Steel |
|---|---|---|---|
Seawater Corrosion Resistance | Exceptional in chloride-rich marine environments | Good, but less effective in high chlorides | Poor, corrodes quickly in seawater |
Temperature Resilience | Reliable at high temperatures | Varies, some alloys weaken at extreme heat | Limited, degrades under high temps |
Fabrication Ease | Easy to weld, cut, and form | Moderate, some alloys harder to work with | Easy, but corrosion limits applications |
Pitting/Crevice Corrosion | Superior resistance in seawater and chlorides | Moderate, depends on alloy | Poor, highly prone to pitting |
Oxidizing Media Resistance | Strong in oxidizing and reducing conditions | Varies, some struggle with oxidizing media | Better in oxidizing, weak in reducing acids |
Durability | Extremely durable, long service life | Moderate to high, depends on alloy | Moderate, shorter lifespan in marine settings |
Chemical Versatility | Handles wide range of corrosives | Good, but less versatile | Limited, fails in aggressive chemicals |
Cost-Effectiveness | Higher upfront cost, long-term savings | Varies, some cheaper but less durable | Low cost, but frequent replacements needed |
Our Hastelloy C-22 plates are built for tough marine environments:
Marine Vessels: Ideal for hull components and seawater cooling systems.
Oil and Gas: Perfect for offshore platforms handling corrosive seawater.
Desalination: Reliable for equipment in high-chloride water treatment systems.
Chemical Processing: Stands up to marine-adjacent corrosive chemical processes.
Power Generation: Tough enough for coastal power plant cooling systems.
These plates are your go-to for systems where corrosion resistance is non-negotiable.
