Pc Wire

Cold drawn pre-stressed steel wire is made of high quality carbon steel rods by surface treatment and cold drawn. The carbon content of steel is in the range of 0.6-0.9. Wash phosphating or other forms of surface treatment, after cold drawing cross-sectional area will generally be reduced by 50-85%, through the cold hardening principle to improve the strength.
Cold drawn pre-stressed steel wire, such as Stabilizing, becomes a low relaxation pre-stressed steel wire that achieves low relaxation properties and significantly improves yield strength, elongation and straightness. If galvanized after the galvanized pre-stressed steel wire, galvanized after stabilization of the wire is called low relaxation galvanized pre-stressed steel wire. The wire is generally delivered in a coil and applied to the rail sleeper, and can be cut and bundled as needed.
冷拉(cold drawn)预应力钢丝用优质高碳钢盘条(high carbon wire rod)经表面处理后冷拔而成,钢的含碳量在0.6-0.9的范围选择,冷拔前要经过酸洗磷化或其它形式的表面处理,冷拔后横截面积一般会减少50-85%,通过冷加工硬化原理提高强度。
冷拔预应力钢丝如再经稳定化处理(Stabilizing),就成为低松弛(low relaxation)预应力钢丝,获得低松弛特性,并明显改善屈服强度、延伸率和伸直性。如果经过镀锌就成为镀锌预应力钢丝,镀锌后经过稳定化处理的钢丝称为低松弛镀锌预应力钢丝。钢丝一般按盘卷状(coil)交付,应用于轨枕(railway sleeper)时,可根据需要定尺切断成捆交付。
Diameter: 4.00mm – 9.00mm.
