随着中国现代化的进程,钢在建筑中的作用也越来越大,而Q345热轧板作为目前成熟的、综合性能强的钢材,使用占比非常高,且多以钢板的形式使用。

With the process of China's modernization, the role of steel in the construction is becoming more and more important, and Q345 hot rolled plate as a mature, comprehensive performance of steel, using a very high proportion, and mostly used in the form of steel plate.

例如著名的“鸟巢”,该建筑项目结构用钢中Q345热轧板规格的钢板需求总量非常庞大,采用的是宝钢钢材Q345

For example, the famous "Bird's Nest", the building project structure steel Q345 hot rolled plate steel demand is very large, using Baosteel steel Q345.

桥梁用结构钢

目前桥梁主要使用得钢材为具有较高强度且易于焊接的钢材。Q345作为专门的桥梁用钢该钢强度高、焊接性能好、抗腐蚀性能强,可节约金属和减轻设备自重,目前正逐渐取代普通碳素钢成为主流。

At present, the bridge is mainly used in steel with high strength and easy to weld steel.Q345 as a special bridge steel, the steel has high strength, good welding performance, strong corrosion resistance, can save metal and reduce the weight of equipment, is gradually replacing ordinary carbon steel as the mainstream.

耐候桥梁钢

Q345钢为基开发出的Q345GNH钢,适用于耐大气腐蚀的热轧、冷轧钢板、钢带和型钢,是介于普通钢和不锈钢的一种物美价廉的钢种,可用于车辆、集装箱、建筑、塔吊和其它结构用的产品。也可用作螺栓连接、铆接和焊接的结构钢,但用作焊接用结构钢的厚度一般不大于16mm

Q345GNH steel developed based on Q345 steel is suitable for hot-rolled, cold-rolled steel plate, steel strip and type steel. It is a cheap steel type between ordinary steel and stainless steel, which can be used for vehicles, containers, buildings, tower cranes and other structural products.It can also be used as bolted, riveted and welded structural steel, but its thickness for welding is generally not greater than 16mm.

Q345钢的拉伸性能显著:韧性较好抗弯和抗剪性能强等。目前各种提高钢材焊接性的技术已比较成熟,而且Q345作为比较早就开发的低合金高强度钢,焊接性能已能适用于各种场合。所以广泛用作一般结构用钢,诸如厂房、建筑、输电线塔等一般用途的焊接金属结构。

The tensile performance of Q345 steel is remarkable: good toughness, strong bending and shear resistance.At present, various kinds of technology to improve the weldability of steel has been relatively mature, and Q345 as a relatively early developed low alloy high strength steel, welding performance has been suitable for various occasions.Therefore, it is widely used as a general structure of steel, such as factories, buildings, transmission line towers and other general uses of welding metal structure.
