Anchor chain is a type of steel chain that has its own characteristics and is different from the size of chains and is produced with special standards for connecting ship anchors. The anchor chains are connected to the ships anchor on one side and to the winches on the other side. These chains are left in the water in order to prevent the movement of the ship, in order to keep it stable in a certain jagged position, which prevent the movement of the ship by hooking on the bottom of the sea and the ocean. The anchor chain in high-tonnage cargo ships has a rod in the middle of the chain beads, which both prevents the change of the length of the chain during contraction and reduces the possibility of foreign objects being placed on the anchor chain. . Strong steel alloys with high tensile strength are used in the production of anchor chains.


The anchor chain is an essential component of a ships anchoring system, providing stability and security in various maritime operations. This essay aims to delve into the different aspects of a ships anchor chain, including its construction, materials used, mainte

Anchor chains are manufactured from marine-grade alloy steel grades U2, U3, and R3 490–770 N/mm² tensile strength. Standard bar diameters range from 12 to 150 mm with a pitch length of 6 times the bar diameter. Minimum breaking force varies from 350 to 12,500 kN depending on grade and diameter. Proof test force is applied at 70% of the minimum breaking force per ISO 1704 standards. These chains undergo normalization and tempering processes to reduce residual stresses and enhance toughness. Each chain link is subjected to magnetic particle inspection MPI before assembly.

The chain structure features resistance welded links with full circumferential flash butt welding. Links are of the marine elongated oval stud link type, with a central stud to prevent deformation under tension. All surfaces are coated with hot-dip galvanizing 85–120 microns or marine-grade epoxy coating. Special fittings include end links, joining links, and swivels, forged from steel with strength matching the chain. These chains are designed for operating temperatures from –20°C to +40°C in saltwater and corrosive marine environments. Production complies with international standards ISO 1704, DIN 8117, and classifications from maritime institutions such as Lloyd’s, DNV, and ABS.

Marine Anchor Chain

The anchor chain is a critical component of a ship mooring system, transferring forces between the anchor and the vessel hull. It is typically manufactured according to IACS and ISO 1704 marine standards. The material is high strength carbon steel or alloy steel. Nominal link diameters range from 14 to over 160 millimeters depending on vessel class. Minimum tensile strength usually falls between 400 and 700 megapascals. Link designs include stud link and studless configurations. Structural safety factors are defined by ship classification rules. Unit length weight is calculated to maintain stable anchoring tension.

Structurally, anchor chains consist of forged links with controlled welding processes. The presence of studs reduces deformation and improves chain stability. The chain is engineered to withstand dynamic loads from waves and currents. Precise dimensional tolerances ensure uniform stress distribution along the chain. The surface is typically protected with marine grade anti corrosion coatings. High resistance to wear and mechanical fatigue extends service life. Each chain length undergoes tensile testing, impact testing, and non destructive inspection.

Anchor chain

The anchor chain is a critical component in maritime and marine transport industries, used to connect and secure the anchor to the vessel’s hull. These chains are typically made from alloy steel or stainless steel, providing very high resistance to tension, abrasion, and marine corrosion. The link diameters of anchor chains generally range from 8 mm to 50 mm, and the length can vary from 10 meters to over 200 meters depending on the vessel and operational requirements. These chains are specifically designed to withstand heavy loads and the forces generated by water currents and waves.

Anchor chains are usually made with reinforced, high-quality welded links to ensure safety and durability in marine operations. They are coated with corrosion-resistant layers, such as galvanization or epoxy paint, to withstand saltwater and harsh environmental conditions. Anchor chains are used in ships, boats, recreational and industrial vessels to keep them securely in position. Their standard design and high strength make anchor chains essential tools for marine safety and port operations.

The anchor chain is a critical component in marine systems for securing ships and vessels at docks and offshore. It is made from alloy or carbon steel with tensile strength ranging from 600 to 900 MPa. Each link undergoes heat treatment and cold rolling to enhance fatigue and wear resistance. Link diameters typically range from 16 to 76 mm, and standard chain lengths vary from 10 to 200 meters depending on vessel type. Links are uniformly oval-shaped to ensure even stress distribution and reduce the risk of failure.

Structurally, the anchor chain consists of durable steel links with polished or galvanized surfaces, providing corrosion and seawater resistance. Each link is precision-machined and forged to withstand high tensile and impact loads. The anchor chain operates reliably in temperatures from −40°C to +200°C and is compatible with marine hooks and shackles. It is widely used in docks, ports, cargo and recreational ships, and marine operations, ensuring safe and stable performance in wet and corrosive environments.

winch anchor chain

The ship winch anchor chain is manufactured from marine grade alloy steel with controlled heat treatment. Its structure consists of calibrated welded links designed according to marine standards. Nominal chain diameters typically range from 14 to 120 millimeters. Common grades include U2 and U3 offering high tensile strength. Breaking load capacity reaches several hundred tons depending on diameter and grade. Dimensional accuracy of the links ensures proper engagement with the winch drum.

Functionally this chain provides safe transmission of tensile force between the anchor and the winch. Surface treatment such as marine coating or special galvanizing improves resistance to seawater corrosion. Design safety factors comply with maritime classification requirements. High resistance to wear and fatigue ensures long service life. Uniform weight and pitch prevent jamming during winch operation. These features guarantee safe anchoring and mooring operations.

Anchor chains are made from high-strength carbon or alloy steel to withstand tensile forces and impact from ship motion and waves. Link diameters typically range from 12 to 56 mm, with standard segment lengths of 12 to 50 meters. The chain surface is protected by hot-dip galvanizing or epoxy coating to resist seawater corrosion. Links are heat-treated for uniform hardness, and U-shaped design distributes radial and axial stresses evenly.

The chain includes connecting links and wear-resistant joints, designed according to ISO 1704 and ASTM A413 standards. Working load limits WLL vary from 5 to 100 tons depending on diameter and length. Link flexibility allows smooth coiling and deployment on the anchor drum. Service life is verified through tensile, impact, and corrosion tests, making it suitable for commercial and recreational vessel anchoring applications.

ship and barge anchor chain

Ship anchors and anchors have different sizes depending on the size of the ship, and the anchors of large cargo ships sometimes weigh more than 50 tons. The anchor chain is actually a type of chain that is connected to the anchor from one side and from the other side to the three-phase winches of the ship that have the task of gathering the anchor chain.
Although sea water is full of very corrosive salts and salts that quickly cause steel to rust, anchor chains are often produced from high grades of steel. In fact, the ability to change the mechanical capabilities of steel by changing the percentage of carbon and, of course, during the heat hardening process, has transformed this alloy to produce anchor chains that are subjected to severe tensile stress and even impact under the influence of sea waves.

anchor chain

The anchor chain is different from the load chain in terms of shape and standard, and the use of a rod between the chain beads prevents the beads from collapsing and sinking into each other. The lack of significant length change in the anchor chain is to prevent excessive displacement of the anchor and the ship after anchoring, which also plays a significant role in preventing the chain from being subjected to tensile stress at once. The size of the anchor chain is chosen depending on the weight of the ship, and sometimes several anchor chains are used for large cargo ships and barges. In terms of usage, traction winches are placed on one side of the anchor chain, and a steel anchor is placed on its open end.

Galvanized anchor chain

Anchor chain is a type of industrial chain that is designed specifically to be used on the ships and within marine industry. anchor chains are usually galvanized following hot dip galvanizing process to have better resistance against the corrosive sea water. there is a different between the lifting chains and anchor chains in design and anchor chains have an extra rod in the middle to refrain from engaging floating objects in the sea.
