Carbon steel master link
Steel wire rope slings are constructed from high-strength alloy steel wires grade 1970 or 2160 N/mm². Sling diameters range from 6 to 100 mm with standard lengths of 1 to 12 meters. Minimum Breaking Load MBL ranges from 2 to 300 tons depending on diameter and construction. Working Load Limit WLL is determined with a 5:1 safety factor for heavy-duty operations. Flexibility is ensured with a minimum bending radius of 3 times the sling diameter. These slings undergo tensile testing up to 80% of breaking load to verify structural integrity.
The construction uses a 6x36 design with an Independent Wire Rope Core IWRC for crush resistance. End fittings are forged steel with a hardness of 40-45 HRC Rockwell C. Socket connections use zinc-copper alloy with joint strength exceeding 95% of rope strength. Surface coating is galvanized or epoxy with 60-80 micron thickness for corrosion protection. Allowable operating temperature ranges from -40°C to 120°C without mechanical degradation. Products are certified and marked according to ISO 8794 and EN 13414-1 international standards.
