Stainless steel composite finish-rolled twisted steel bar and manufacturing method thereof
The invention discloses a stainless steel composite finish-rolled twisted steel bar. The stainless steel composite finish-rolled twisted steel bar comprises a stainless steel corrosion-resistant outer layer, a low-alloy steel core and a metallurgical bonding transition layer formed by hot rolling permeation of the stainless steel corrosion-resistant outer layer and the low-alloy steel core in the compounding process, the stainless steel corrosion-resistant outer layer is coated on the periphery of the low-alloy steel core, and the metallurgical bonding transition layer is an extension bonding layer which uniformly permeates from the stainless steel corrosion-resistant outer layer to the low-alloy steel core; the thickness of the stainless steel corrosion-resistant outer layer ranges from 0.10 mm to 2.00 mm, the thickness of the metallurgical bonding transition layer ranges from 0.02 mm to 0.15 mm, and the thickness of the stainless steel corrosion-resistant outer layer is 0.6%-10% of the radius of the finish-rolled twisted steel.
本发明公开了一种不锈钢复合精轧螺纹钢筋，包括：不锈钢耐腐蚀外层和低合金钢钢芯，以及所述不锈钢耐腐蚀外层与所述低合金钢钢芯在复合过程中热轧渗透所形成的冶金结合过渡层，所述不锈钢耐腐蚀外层包覆在所述低合金钢钢芯外周，所述冶金结合过渡层是从所述不锈钢耐腐蚀外层至所述低合金钢钢芯均匀渗透的延伸结合层；所述不锈钢耐腐蚀外层的厚度为0.10mm‑2.00mm，所述冶金结合过渡层的厚度为0.02mm‑0.15mm，所述不锈钢耐腐蚀外层厚度是所述精轧螺纹钢筋半径的0.6％‑10％。
