Steel Core Steel Wire Rope

Steel Core Steel Wire Rope

Description：

The core of steel wire rope consists of a steel wire strand or an independent steel wire. Compared with natural fiber core steel wire rope, steel core steel wire rope has more wear resistance,more extrusion resistance, softness is relatively low.Because of abrasion resistance and compression resistance, steel core wire rope is generally applicable to hoist or winch.It is suitable for high temperature or multi-layer winding occasions.

Detailed Information：

1. Common structure: Almost all structure.

2. Surface treatment: Oiled, ungalvanized steel wire rope, galvanized steel wire rope, coated steel wire rope, etc. (as requirements)

3. Material: Carbon steel, stainless, etc.

4. Diameter: Customized according to customer needs.

5. Breaking load: Customized according to customer needs.

6. Packaging: Wood disc packaging, ABS shaft packaging, according to customer's specific requirements.

7. Application: Crane, windlass,elevator, etc.

8. Certificate & Standard:

Certificate : ABS,LR,CE,CCS, BV,DNV

Standard : GB8919, GB/T 20067,ISO, ASTM, EN, JIS, etc.

Advantages:

1. Steel core steel wire rope is more resistant to high temperature than fiber core steel wire rope.

2. The breaking force of steel core steel wire rope is larger than that of fiber core steel wire rope.

3. The elastic modulus of steel core steel wire rope is larger than that of fiber core steel wire rope.

4. Steel core steel wire rope is more stable than fiber core steel wire rope’s diameter.

5. Steel core steel wire rope is more resistant to extrusion, wear resistance and longer service life than fiber core steel wire rope.

Comparison of performance characteristics of NFC, SFC, and IWRC elevator rope:

Typical cross sections of wire ropes
Type	NATURAL FIBER CORE (NFC)	SYNTHETIC FIBER CORE (SFC)	INDEPENDENT WIRE STRAND CORE (IWS)
Diameter uniformity	Poor Affected by the quality of the fiber core	About good Fiber core diameter is relatively uniform	Very good
Dimensional stability	Poor	About good	Very good
Structural elongation	≯0.25%	≯0.25%	≯0.15%
Percentage of total elongation	≯0.50%	≯0.50%	≯0.25%
Elasticity modulus	74700-80400	74700-80400	82900-98700
Breaking load	Relatively small	Similar to NFC	Large More than 25% larger than the same diameter fiber core rope
Fatigue life	Relatively short steel core	Relatively short steel core	Long Under the same load condition, its fatigue life is 1 times longer than that of fiber core rope
Oil content	Good oil storage. Less maintenance	Poor oil immersion ability, and can not work at too low or too high temperature	Poor oil immersion ability. Need regular maintenance, fill oil.
Extrusion resistance	The diameter is easy to deform under extrusion	About good	Diameter is not easy to deform, not suitable for V-groove
Anti-wear	Good	——	Poor
Flexibility	good	good	Poor
Cost	Relatively cheap cost	Higher cost	High cost
