Uncoated (Bright) Steel Wire Ropes, the grade of the wire the different minimum breaking strength

Model Number: CHBSWR20130529 Key Specifications/Special Features: Wire ropes made of uncoated wires are used in applications in which the ropes are normally discarded because of wear and fatigue and not due to corrosionEven with these ropes, some corrosion protection can be achieved by proper lubrication of the ropesThe grade of the wire is the minimum breaking strengthThe most common grades used are: 1,370, 1,770, 1,960, 2,160N/mmOther grades are used for some special applicationsThe North American market uses a different scale of grades according to US federal specification RR-W-410: traction steel mild plow steel (MPS), plow steel (PS), improved plow steel (IPS), extra improved plow steel (EIPS), extra improved plow steel (EEIPS)The most common grade for general purpose wire ropes is IPS which is quite close to 1,770N/mm, grade EIPS is close to 1,960N/mmThe actual strength of the steel in these grades varies with the wire diameterThe core:Fiber core (FC), usually polypropylene (PC), sometimes hemp (HC) and sisalIndependent wire rope core (IWRC)Wire strand core (WSC)IWRC and WSC are sometimes referred to as steel wire core or steel centerConstruction: expressed in numbers of strands x number of wiresFor example: 6 x 25 indicates that the wire rope consists of 6 strands, which in turn have 25 individual wiresLay: right regular lay (RRL), right lang lay (RLL), left regular lay (LRL), left lang lay (LLL) Shipping Information: FOB Port: Shanghai Lead Time: 10 - 15 days
