Grades of Wire Rope

Grades of Wire Rope

The three primary grades of wire rope are Plow steel, Improved Plow steel, and Extra Improved Plow Steel.

Plow  Steel  

Plow  Steel  wire  rope  is  unusually  tough  and strong. This steel has a tensile strength of 1570 N/mm2

Improved Plow Steel

Improved Plow Steel wire rope is one of the best grades of rope available, and is the most commonly used rope. Improved plow steel is stronger, tougher, and more resistant to wear than plow steel. This steel has a tensile strength of 1770 N/mm2

Extra Improved Plow Steel

Extra Improved Plow Steel (EIPS) is used in the manufacturing of wire ropes for special installations, where maximum rope strength is required, and conditions of use permit some applications such as mine shaft hoisting, where increased tonnages on existing skips and drums can be tolerated, and where conditions such as sheave and drum diameters are favorable to its use. This steel has a tensile strength of 1960 N/mm2
