热轧与冷轧的区别
钢有多种等级、规格、形状和表面处理——世界钢铁协会列出了3500多种不同等级的钢，每种钢都具有独特的性能。钢的种类繁多，这意味着钢可以广泛用于基础设施、电器、车辆、风力涡轮机和更多的应用领域。
Steel comes in many grades, specifications, shapes, and finishes—the World Steel Association lists over 3,500 different grades of steel, each with unique properties. The various types mean that steel can by widely used in infrastructure, appliances, vehicles, wind turbines, and many more applications.
然而，针对每种应用优化钢的性能不仅仅是改变化学成分。钢材的制造工艺也会对钢材产品产生重大影响——即使等级和规格相同。预制钢产品之间的主要区别之一是热轧钢和冷轧钢之间的区别。
Optimizing steel’s properties for each application goes beyond changing the chemical composition, however. The manufacturing processing of steel can also have a significant impact on steel products—even when the grades and specifications are the same. One key distinction among pre-fabricated steel products is the difference between hot rolled and cold rolled steel.
