Corrosion Resistant Chain Manufacturer
Our commitment: Keep your equipment running at peak performance – with high-performance chains you can rely on.
Nickel Plated Chain
Corrosion-Resistant Chains – Engineered for wet, chemically aggressive, marine, and food-contact environments. MATECH offers a full range of standard stainless steel chains, galvanized carbon steel chains, and nickel-plated chains. We also support customization of material grades, coating thicknesses, pitches, and non-standard attachments. Every batch comes with a salt spray test report and material certificate, guaranteeing reliable performance in harsh conditions.
Product Series
Manufactured entirely from 304 or 316 stainless steel. Offers excellent resistance to acids, alkalis, salt spray, and moisture. Ideal for high-rust-protection applications such as food processing, chemical plants, and offshore engineering.
Working Principle of Corrosion-Resistant Chain
Corrosion-resistant chains are driven by sprockets. Their protection against rust and chemical attack comes either from the stainless steel material itself or from zinc/nickel coatings applied to carbon steel. Stainless steel chains rely on a passive chromium oxide film for protection. Coated carbon steel chains protect the base metal through sacrificial zinc anodes (galvanized) or a nickel barrier layer (nickel-plated).

Frequently Asked Questions
1
What are the main differences between stainless steel chains and galvanized chains?
Stainless steel chains offer complete corrosion resistance. Even if the surface is scratched, their passivation layer can self-repair, making them suitable for long-term use in humid conditions or chemical environments； Galvanized chains rely solely on surface protection; once the coating is scratched, they are prone to rust, so they are recommended only for indoor, dry, or mildly humid conditions.
2
How to choose between 304 and 316 stainless steel chains?
Grade 304 is suitable for food processing, general chemical applications, and indoor humid environments. Grade 316 contains added molybdenum, which significantly enhances resistance to chloride-induced pitting corrosion, making it as the preferred choice for coastal, marine, or halogen- and bleach-containing environments. If welding attachments are required, 316L is recommended to minimize the risk of intergranular corrosion.
3
What is the salt spray resistance of nickel-plated chains?
Standard electroplated nickel typically withstands 96–200 hours in a neutral salt spray test. Thicker nickel plating or electroless nickel plating can exceed 500 hours, and provides extremely uniform coating thickness even on complex-shaped attachments. The actual performance depends on the plating thickness and post-treatment.
4
Can stainless steel chains be used in high-temperature environments?
Yes. 304 stainless steel can handle temperatures up to about 800°C, while 316 can handle up to 850°C. Please note that their mechanical strength drops at high temperatures, so material selection should be based on actual working conditions.
5
How to quickly select a suitable surface treatment according to working conditions?
• Dry indoor environments and general mechanical interiors: Zinc plating is sufficient and most cost-effective.
• Humid conditions, frequent wiping and cleaning, or aesthetic requirements: Nickel plating provides both protection and aesthetics.
• Long-term water immersion, chemical spraying, or outdoor exposure: Stainless steel is recommended.
• High salt-spray coastal areas and offshore platforms: 316 stainless steel or duplex stainless steel is recommended.
• Humid conditions, frequent wiping and cleaning, or aesthetic requirements: Nickel plating provides both protection and aesthetics.
• Long-term water immersion, chemical spraying, or outdoor exposure: Stainless steel is recommended.
• High salt-spray coastal areas and offshore platforms: 316 stainless steel or duplex stainless steel is recommended.
6
What about the magnetism of stainless steel chains?
Austenitic stainless steels (304/316) are normally non-magnetic, but may become slightly magnetic after cold processing. This does not affect corrosion resistance, and the chains remain safe to use.If strict non-magnetic requirements apply, such as in medical or electronic equipment, please let us know in advance. We can perform full annealing or other demagnetization treatments. Martensitic stainless steels (e.g., 420) are magnetic.
7
Can zinc-plated chains be used in the food industry?
Not recommended. The zinc coating may peel or flake off and is harmful to human health. Stainless steel chains are recommended for food-grade applications.
8
What should be done if the chain coating wears and peels off during operation?
On-site repair is not possible, as this marks the end of the chain’s service life. The chain can be replaced or fully re-coated, though re-coating can be costly. We can recommend choosing an adequate initial coating thickness based on your expected replacement cycle, to ensure full protection throughout the chain’s service life.
9
Do stainless steel chains require lubrication?
Yes. Corrosion resistance does not equal wear resistance. The pins and bushings still need lubrication to reduce friction. For food industry applications, food-grade lubricants are recommended.
10
Can you provide matching corrosion-resistant sprockets?
Yes. We offer stainless steel sprockets or zinc-/nickel-plated carbon steel sprockets to ensure compatibility with the chains.
11
What is the minimum order quantity and lead time for custom corrosion-resistant chains?
The minimum order for custom chains is usually 100 meters. Sample orders are negotiable.
Lead time: Samples: 7–30 days; Bulk orders: 15–45 days
For urgent corrosion-resistant projects, we can arrange expedited production and delivery.
