Marine Anchor Chain Types
The anchor chain is used to connect a ship hull and anchor,,with the function of passing the anchorage force and the external force of the ship.
A complete anchor chain consists of several short chains by using shackles, swivals.Bellow is the normal catagory of the anchor chains types.
(1)According to the link structure: the anchor chain is divided into two types: the stud chain and the studless hain. Under a same condition, the strength of the stud chain is larger than that of the studless chain. The tensile strength is about 20% bigger, and the deformation is small, and it is not easy to twist when stacked. Therefore, it is widely adopted on the ship. The studless chain is usually used only for small boats.
(2)According to the manufacturing methods: chain can be divided into cast steel chain (cast steel cable), welded chain( weldedcable) and forged chain (forged cable), etc. The characteristics of welded chain are: have advanced technology, simple, low manufacturing cost, high quality, more than other kinds of anchor chain. Currently it is widely used for ships. Cast steel anchor chain is characterized by high strength, good rigidity, no looseness and long service life. The disadvantage is that the manufacturing cost is higher and the impact load is poor.
(3)According to the grade of steel: there are three grades: Al, A2 and A3. The bigger the grade, the bigger he intensity. The steel grades used for the production of stud chain are classified as AMl, AM2 and AM3, and AMl anchor chain steel is composed of sedation steel, AM2 and AM3 chain steel is composed of sedation and fine crystal processing steel.
