High-strength corrosion-resistant stainless steel coated steel wire for bridge cable and preparation method of high-strength corrosion-resistant stainless steel coated steel wire
The invention provides a high-strength corrosion-resistant stainless steel coated steel wire for a bridge cable. The high-strength corrosion-resistant stainless steel coated steel wire comprises a stainless steel corrosion-resistant outer layer, a high-strength steel core and a metallurgical bonding transition layer, and the stainless steel corrosion-resistant outer layer and the high-strength steel core are assembled and then hot-rolled, so that the metallurgical bonding transition layer is formed on the contact surface of the stainless steel corrosion-resistant outer layer and the high-strength steel core. The diameter of the high-strength corrosion-resistant stainless steel coating steel wire for the bridge cable is 3-7 mm, the thickness of the stainless steel corrosion-resistant outer layer is 1-8% of the diameter of the composite steel wire, and the thickness of the metallurgical bonding transition layer is 0.02-0.10 mm. The high-strength steel core is made of alloy steel and comprises, by weight, 0.8%-0.95% of C, 0.8%-1.3% of Si, 0.6%-0.9% of Mn, 0.2%-0.4% of Cr, 0.05%-0.2% of Mo, 0.1%-0.3% of Ni, 0.02%-0.08% of Ti, 0.03%-0.08% of V, 0.02%-0.06% of Al and the balance Fe and inevitable impurities. The high-strength corrosion-resistant stainless steel coated steel wire for the high bridge cable, the coated steel wire has the characteristics of high strength, corrosion resistance, excellent performance and stable performance.
