7X19 stainless steel wire rope factory direct multi-strand stainless steel wire rope

Material: 201 304 316 double no structure: 7 * 19-133 filaments, seven shares of 19 wire diameter: 1.5mm-30.0mm one hundred meters Weight: 0.9-360kg / 100m Strength: 1570Mpa 19 * 7 and 7 * 19 What is the difference in the end? In the latest national standard wire rope GB / T20118-2006 and no 19 * 7 * 7 and 19 of these two markers code, just called us customary, in the national standard wire rope 19 can be marked as 18 * 7 * 7 + IWS, and 7 * 19 can be marked as 6 * 19 + IWS, wire rope 7 * 19 * 7 and 19 are two different concepts, the first rope 19 * 7 represents a total of 19 stocks, each of which has seven steel stocks ; 7 * 19 on behalf of the rope while seven stocks, each of which has 19 steel stocks; 19 * 7 is made from two layers made of layered twist, twist the inner and outer layers to the contrary, if the outer layer is left twist, then within layer is the right twist; if the outer right twist, then twist the inner left; the rope specifications under the same circumstances (wire diameter), made of twisted wire rope diameter is almost the same, but the number of wires used in almost are 133 steel; but breaking strength is different, the same tensile strength than about 19 * 7 7 * 19 is 10% by weight of the rope is 19 * 7 large, but also about 10% larger; from rope performance point of view, 19 * 7 is not rotating shares belong to multi-rope, lifting weights, rope spinning almost does not happen, can improve work efficiency; rope 7 * 19 for a single or a high-lift upgrade due to the rotation when the rope And playing twist, not only affects the life of the rope, and the impact to enhance the efficiency and safety of operating personnel
