Japanese Patent JP2022155033
Kind Code:
A
Abstract:
To provide a plated steel wire and a clad plated steel wire having high absorption energy performance, and a wire mesh having high absorption energy when receiving a falling rock, and a small overhang of the wire mesh when receiving the falling rock, and a rock fall protection work.SOLUTION: Provided is a plated steel wire having a predetermined steel composition, wherein a metal structure in a central region of a longitudinal section has a total area ratio of ferrite and pearlite to an entire structure of 90.0% or more, and an area ratio of pearlite to the entire structure of 47.5% or more, and when the total area ratio of ferrite and pearlite to the entire structure is less than 100%, a remainder is composed of at least one of cementite and bainite, and when a tensile test is performed, the tensile strength is 850 to 2,000 MPa. a uniform elongation of 4.0 to 8.0%. Also provided are a wire mesh using the same and a rock fall protection work.SELECTED DRAWING: None
