1、 Material performance and durability

冷弯型钢：

Cold formed steel:

由于冷弯过程中材料发生塑性变形，弯角处会出现冷弯效应，导致强度提高、塑性降低。这种特性使得冷弯型钢在某些需要高强度的应用中具有优势。

Due to plastic deformation of the material during the cold bending process, a cold bending effect occurs at the corners, resulting in an increase in strength and a decrease in plasticity. This characteristic gives cold-formed steel an advantage in certain applications that require high strength.

冷弯型钢的重量轻、功能多，能工业化生产，是一种有发展前途的结构。然而，其厚度较小，如何防止锈蚀以增加耐久性是必须重视的问题。因此，在设计时需要注意使用环境，并采取合理的防腐措施。

Cold formed steel is lightweight, multifunctional, and capable of industrial production, making it a promising structure for development. However, its thickness is relatively small, and how to prevent rust to increase durability is a crucial issue that must be taken seriously. Therefore, when designing, attention should be paid to the usage environment and reasonable anti-corrosion measures should be taken.

热轧型钢：

Hot rolled steel:

热轧型钢经过高温加热与快速冷却的处理过程，钢材内部的晶粒结构得到优化，提高了材料的屈服强度和抗拉强度。

The hot-rolled steel undergoes a process of high-temperature heating and rapid cooling, which optimizes the grain structure inside the steel and improves the yield strength and tensile strength of the material.

热轧型钢具有出色的韧性和抗冲击能力，适合在复杂应力环境下长期使用。

Hot rolled steel has excellent toughness and impact resistance, making it suitable for long-term use in complex stress environments.

热轧型钢的表面经过热处理后会形成一层氧化皮，虽然需要进一步处理以满足特定环境下的使用要求，但这一层保护膜在一定程度上减缓了钢材与外界环境的直接接触，从而延长了使用寿命。

After heat treatment, a layer of oxide scale will form on the surface of hot-rolled steel. Although further treatment is needed to meet specific environmental requirements, this protective film to some extent slows down the direct contact between the steel and the external environment, thereby extending its service life.

二、应用场景与耐用性

2、 Application scenarios and durability

冷弯型钢：

Cold formed steel:

广泛应用于轻型钢结构、汽车、集装箱、钢结构建筑等领域。在这些领域中，冷弯型钢的截面经济合理、品种繁多、外观良好等特点得到了充分发挥。

Widely used in fields such as lightweight steel structures, automobiles, containers, and steel structure buildings. In these fields, the economically reasonable cross-section, diverse varieties, and good appearance of cold-formed steel have been fully utilized.

在需要高精度和高表面质量的场合，冷弯型钢是更好的选择。同时，其重量轻的特点也使得在需要减轻结构重量的应用中具有优势。

In situations where high precision and high surface quality are required, cold-formed steel is a better choice. Meanwhile, its lightweight feature also gives it an advantage in applications that require reducing structural weight.
