# Marine Black Paint Anchor Chain - Dedicated Anchor Chain for Marine Hardware
A practical hardware accessory designed specifically for ship anchoring scenarios. With black paint protection and stabilizing performance as its core features, it adapts to the daily anchoring needs of various vessels, making it a reliable piece of marine hardware.

## Core Materials and Black Paint Protection

- Made with high-strength carbon steel or alloy steel as the base material, the material is rigid and has excellent tensile strength, able to withstand the tensile impact during ship anchoring, preventing breakage and deformation.

- The surface is treated with a professional black paint process, resulting in a uniform and dense coating with strong adhesion, effectively isolating it from seawater, salt spray, and humid air corrosion, delaying rust and extending service life.

- The smooth and wear-resistant black paint surface resists friction and impacts in the marine environment, reducing scratch damage, while also facilitating identification and cleaning maintenance.

## Structural Design and Usage Characteristics

- The chain links are manufactured using precision forging and welding processes, with full and strong weld seams, tight and smooth connections, and smooth, non-jamming operation during retraction and extension, providing strong stability when used with various anchors.

- Available in a full range of sizes to fit various tonnage vessels including fishing boats, cargo ships, yachts, and workboats, meeting the needs of near-shore anchoring, dock berthing, and long-term berthing.

- A well-balanced weight and strength design ensures both stability and ease of operation. Effortless deployment and retrieval, convenient storage and handling, and compatibility with various marine anchor winches.

## Quality and Compatibility Advantages

- Manufactured strictly according to marine hardware industry standards. Each chain link undergoes tensile testing and dimensional calibration, ensuring high precision and small tolerances, meeting marine anchoring safety regulations.

- The black paint coating offers strong weather resistance, resisting peeling and fading even in extreme temperatures and exposure to wind, rain, and sunlight, maintaining its appearance integrity and protective performance.

- High versatility; perfectly compatible with standard anchors, shackles, and other accessories. Easy installation requires no additional modifications, reducing operating costs.

Manufacturing Process:

# Marine Black Paint Anchor Chain Production Process

Focusing on "strong and tough base material + black paint protection," the process employs multiple precision steps to control structural strength and corrosion resistance, adhering to marine hardware standards throughout to produce reliable anchor chains suitable for the marine environment.

## 1. Raw Material Selection and Cutting

- High-strength carbon steel or alloy steel billets are selected. Material composition and hardness testing ensure the base material meets the tensile strength requirements for marine anchor chains.

- Billets are cut according to preset link dimensions, precisely controlling the length and cross-sectional flatness of the raw materials to lay the foundation for subsequent forming.

## 2. Link Forming and Welding

- CNC bending equipment is used to process the raw materials into standard links, ensuring consistent curvature and precise dimensions for each link, with errors controlled within industry standards.

- Automatic submerged arc welding or argon arc welding technology is used to weld the link interfaces. The weld seam is fully filled, free of porosity and cracks. Weld beads and spatter are immediately removed after welding to ensure a smooth link surface.

- Perform tensile testing on the welded chain links to verify weld strength and overall load-bearing capacity, and reject defective products.

## 3. Shaping and Grinding

- Use shaping equipment to correct the size and angle of the chain links, ensuring tight connection, smooth movement, and no jamming during extension and retraction.

- Perform rough and fine grinding on the entire anchor chain to remove surface burrs, scratches, and processing residues, making the surface smooth and flat, preparing for painting.

## 4. Rust Removal and Pretreatment

- Use shot blasting to thoroughly remove oxide scale, rust, and oil stains from the anchor chain surface, enhancing coating adhesion.

- After rust removal, perform degreasing and phosphating treatment to form a conversion film on the surface, further improving rust resistance and preventing paint peeling and blistering.

- Dry the treated anchor chain to remove surface moisture, ensuring a dry and clean painting environment.

## 5. Black Paint Spraying and Curing

- Marine-grade anti-corrosion black paint is selected, using electrostatic or high-pressure spraying processes to evenly cover the anchor chain surface, ensuring the coating thickness meets standards and there are no missed areas or runs.

- After spraying, the chain is placed in a curing oven for high-temperature curing, allowing the black paint to bond tightly to the substrate, improving the coating's wear resistance and weather resistance, and ensuring it is not prone to fading or peeling in marine environments.

- A second inspection is conducted after curing, and any missed areas or uneven coatings are reapplied to ensure comprehensive protection.

## 6. Finished Product Inspection and Packaging

- Comprehensive quality inspection is conducted, including coating adhesion testing, dimensional accuracy calibration, tensile testing, and visual inspection, to ensure compliance with marine hardware industry standards.

- The chain is cut to specified lengths according to customer requirements, equipped with dedicated connectors, and packaged in moisture-proof and scratch-resistant materials to prevent damage to the coating and chain during transportation.

# Marine Black Paint Anchor Chain Product Features
Focusing on the core needs of marine anchoring, this product features strong protection, high stability, and high adaptability, balancing economy and practicality. It is a reliable hardware equipment for various types of vessels.

## Strong Corrosion and Wear Resistance, Extended Service Life

- The surface is coated with marine-grade epoxy coal tar paint or tar pitch, applied through 2-3 professional coating processes, achieving a dry film thickness of over 60μm, forming a dense protective barrier.

- The coating has strong adhesion and is resistant to seawater corrosion, reducing the seawater corrosion rate by approximately 40%. It also resists friction, impact, and salt spray damage, extending the maintenance cycle to 12-18 months.

- The smooth, wear-resistant black paint surface is not prone to peeling or fading, reducing wear and tear on the chain from the marine environment and significantly reducing subsequent maintenance costs and downtime.

## High-Strength Structure, Safe and Controllable Anchoring

- Utilizing high-strength carbon steel or alloy steel base materials such as CM490/CM690, combined with a stopped chain link structure, its strength far exceeds that of unstoppable anchor chains, exhibiting excellent tensile strength.

- The chain links are precision forged and welded, with full, defect-free welds. Non-destructive testing using X-rays and magnetic particle analysis shows a fracture load range of 92kN-7060kN, capable of withstanding tensile impacts under complex sea conditions.

- Manufactured strictly according to shipbuilding industry standards, and certified by authoritative bodies such as BV, CCS, and LR, ensuring high dimensional accuracy and small tolerances, guaranteeing stable anchoring without loosening.

## Strong Practicality and Adaptability, Convenient Operation

- Complete specifications, with chain link diameters ranging from 17.5mm to 150mm, suitable for vessels of different tonnages, including fishing boats, cargo ships, yachts, and offshore platforms, meeting various scenarios such as near-shore anchoring and dock berthing.

- The chain links connect tightly and smoothly, allowing for seamless deployment and retraction without jamming. It is perfectly compatible with various anchors, anchor winches, and shackles, requiring no additional modifications for installation.

- The weight and strength are well-balanced, simplifying storage and handling. It adapts to standard shipboard operations, reducing operational complexity.

## Uniform Appearance, Balancing Aesthetics and Practicality
