Mirror Polished Marine Anchor Chain 316 Stainless Steel Boat Anchor Chain

Product Description:

Material Advantages:

Core Material Advantages:

Forged from 316 stainless steel, the inclusion of molybdenum enhances corrosion resistance, allowing it to withstand harsh marine environments such as seawater, salt spray, and humidity, and resisting rust and deterioration over long-term use.

High material strength and excellent toughness enable it to withstand the tensile impacts of anchoring, preventing breakage or deformation and ensuring navigational safety.

Mirror Polishing Process: The surface undergoes precision mirror polishing, resulting in high gloss, a delicate texture, and a bright metallic finish, enhancing the ship's refined appearance.

The smooth, burr-free polished surface reduces marine organism adhesion, lowers seawater resistance, facilitates deployment and retrieval, and makes cleaning and maintenance easier.

Manufacturing Process:

# 316 Stainless Steel Mirror Polished Marine Anchor Chain Production Process

Quality is guaranteed through precision craftsmanship. From raw materials to finished products, the chain undergoes multiple core processes, with strict control over precision and performance throughout, ultimately producing marine anchor chains that combine corrosion resistance and a mirror-like finish.

## 1. Raw Material Selection and Pre-treatment

- 316 stainless steel billets conforming to international standards are selected. The material composition is verified through spectral testing to ensure that the molybdenum content meets standards, guaranteeing a solid foundation for corrosion resistance.

- The stainless steel billets are cut and straightened to remove surface oxide scale and impurities, laying a smooth base for subsequent processing.

## 2. Chain Link Forming and Welding

- CNC bending machines are used to process the stainless steel raw materials into chain links of preset specifications, ensuring that each chain link has uniform dimensions and standard curvature.

- Argon arc welding technology is used for precise welding of the chain link interfaces, resulting in full and strong welds. After welding, weld beads are removed to ensure a smooth, protrusion-free surface on the chain links.

- Perform tensile testing on the welds to check if the weld strength meets the ship's anchoring tensile strength requirements, and reject any substandard products.

## 3. Preliminary Grinding and Shaping

- Rough grinding of the entire anchor chain using mechanical grinding equipment removes surface scratches, oxide spots, and residual burrs.

- Fine shaping of the chain link joints ensures smooth chain movement without jamming, guaranteeing easy extension and retraction.

## 4. Mirror Polishing

- Through three polishing processes—rough, medium, and fine—the surface smoothness of the anchor chain is gradually improved.

- In the fine polishing stage, specialized polishing wax and high-precision polishing equipment are used to repeatedly grind until the surface achieves a mirror-like gloss. After the gloss level meets the standard, cleaning and dewaxing are performed.

## 5. Corrosion Protection and Testing

- Passivation treatment is applied to the polished anchor chain to form a dense protective film on the surface, further enhancing its resistance to seawater corrosion.

- Conduct comprehensive quality inspections: including surface gloss testing, dimensional accuracy calibration, tensile strength testing, and corrosion resistance testing, while verifying non-magnetic properties.

## 6. Finished Product Inspection and Packaging

- Manually re-inspect the anchor chain appearance to ensure it is free of scratches, defects, and potential defects at welds, meeting mirror polishing standards and marine usage specifications.

- Cut to specified lengths according to customer requirements, equipped with dedicated connectors, and sealed with moisture-proof and scratch-resistant packaging materials to prevent surface damage during transportation.

Features:

316 stainless steel mirror-polished marine anchor chains are characterized by strong corrosion resistance, high strength, and beautiful appearance. Here are the details:

- **Excellent Corrosion Resistance:** Made of 316 stainless steel, containing alloying elements such as chromium, nickel, and molybdenum, it forms a dense passivation film on the surface, effectively resisting corrosion from seawater, salt spray, acids, and alkalis. It can be used for extended periods in harsh marine environments without easily rusting or deteriorating.

- **High Strength and Toughness:** The material itself has high strength. After appropriate manufacturing processes and heat treatment, it provides sufficient tensile strength and impact toughness, capable of withstanding the enormous tensile impacts during anchoring without easily breaking or deforming, ensuring the safety of the vessel under various sea conditions.

- **Mirror-Polished Appearance:** The surface undergoes precise mirror polishing, resulting in extremely high gloss and a delicate texture. This not only enhances the vessel's aesthetic appearance but also reduces the adhesion of marine organisms, lowers seawater resistance on the anchor chain, makes the anchor chain easier to deploy and retrieve, and facilitates cleaning and maintenance.

- **High Dimensional Accuracy:** Strict adherence to relevant standards such as ISO G43 and DIN 766 during production ensures high dimensional accuracy of the chain links. The tight and smooth connections between links guarantee the stability and reliability of the anchor chain during use, allowing for seamless integration with various ship anchors and anchor winches.

- **Excellent Temperature Resistance:** 316 stainless steel possesses excellent thermal stability, maintaining stable performance in environments with alternating high and low temperatures. It does not experience significant strength reduction or deformation due to temperature changes, adapting to varying sea and seasonal temperature conditions.

- **Non-Magnetic:** 316 stainless steel is inherently non-magnetic, preventing interference with navigation equipment and other electronic instruments on ships. This ensures the normal operation of equipment during navigation, making it safer and more reliable.

- **Compliant with Industry Standards:** The product complies with relevant international and domestic industry standards such as ISO G43 and NACM, and has passed CE, ISO 9001, and SGS certifications. Each chain link undergoes rigorous tensile testing and quality inspection, guaranteeing product quality and safety.
