The knowledge about customized marine steel wire rope

First ,let me tell you the basic knowledge about marine steel wire rope at here:

Composition: wire strand + cor

Material; High quality carbon steel, generally ranging from 0.4-4mm in diameter;

Surface:

Smooth and galvanized. Surface condition marking code: smooth steel wire -- NAT; Grade A galvanized steel wire -- ZAA; Grade AB galvanized steel wire -- ZAB; Grade B galvanized steel wire -- ZBB;

Rope core: fiber core and metal core

The role of fiber core:

1, reduce the contact stress between the strands;

Relieve bending stress;
Store lubricating oil to prevent rust inside the rope;
The role of the metal core: 1.

Pressure resistance;
It is not easy to be deformed;(disadvantages -- poor flexibility and corrosion resistance)
Core marking: synthetic fiber core -- FC;Natural fiber core -- SF;Wire rope core -- IWR;Wire core -- IWS;

marine steel wire rope commonly used material is carbon .



low carbon marine steel wire rope :carbon content 0.10% -- 0.30%, generally rolled Angle steel, channel steel, i-beam steel, steel pipe, steel strip or steel plate.It is used for making all kinds of structural parts, containers, boxes, stoves and farm tools, etc. (anchor chain steel is mainly CM490 and CM690, which is a low carbon steel, mainly containing manganese);

medium carbon marine steel wire rope: carbon content 0.30% -- 0.60%, the strength, hardness is better than low carbon steel, can be directly used hot rolled steel, cold drawn steel, can also be used after heat treatment, the most widely used, a large number of various mechanical parts;

high carbon marine  steel wire rope: carbon content 0.60% -- 1.70%, also known as tool steel, can be heat treatment, get very high hardness, can be made into drill, reamer, tap, etc.
