Wire diameter and tensile strength of hard steel wire

Blank wire diameters in this table and wire diameters not in the table are basically custom-made materials, and the cost may increase. Some manufacturers produce wire diameters other than those listed in the table, but confirmation is required.

Each wire diameter and tensile strength are shown in the table below.

^The unit is N/mm2
