ASTM A1023 6x12 Fiber Core Steel Wire Rope

The ASTM A 1023 classification 6x12 fiber core is a type of steel wire rope with specific construction details. It consists of 6 strands, and each strand contains 12 wires, making a total of 72 wires (excluding the steel core). There is 1 layer of strands and 1 layer of wire. A typical example of this rope is the "6x12 Running Rope FC".

In terms of its physical characteristics, it comes in various nominal rope diameters. For instance, it ranges from 5/16 in. (7.9 mm) to 1 in. (25.4 mm). Along with the diameter, it has corresponding approximate nominal length masses and minimum breaking forces. The approximate nominal length mass varies from 0.1 lb/ft (0.152 kg/m) for the 5/16 in. diameter to 1.04 lb/ft (1.555 kg/m) for the 1 in. diameter. The minimum breaking force ranges from 2 tons to 23 tons, and to convert tons to kilonewtons (KN), one should multiply tons by 8.896.
