ISO 20805:2017适用于卷制的连续热轧钢板,其屈服强度更高,成型性更好,冷成型厚度更大。可以对钢进行处理,以实现夹杂物控制。通常在交付状态下使用。
由于更高的强度和更高的成形性相结合,有可能在获得更好的焊接性的同时节省质量。
该产品适用于需要比普通高屈服强度钢板具有更好成形性的零件制造应用。
钢板采用多种牌号生产,以满足不同的应用要求。
ISO 20805:2017不适用于
-锅炉或压力容器用钢,
-指定为商业质量、图纸质量或结构质量的钢材,
-轧制成冷轧产品的钢材,
-指定为耐候钢的钢,具有更高的耐大气腐蚀性,或
-这些产品在中厚板轧机上轧制。
ISO 20805:2017 is applicable to continuous hot-rolled steel sheet in coils of higher yield strength with improved formability and heavy thickness for cold forming. The steel can be treated to achieve inclusion control. It is generally used in the as-delivered condition.
As a result of the combination of higher strength and improved formability, it is possible to obtain savings in mass along with better weldability.
The product is intended for applications where parts are to be fabricated requiring better formability than is provided by normal high-yield-strength steel sheet.
The steel sheet is produced in a number of grade designations designed to be compatible with differing application requirements.
ISO 20805:2017 does not apply to
- steels intended for boilers or pressure vessels,
- steels designated as commercial quality, drawing quality or structural quality,
- steels rolled to cold-reduced products,
- steels designated as weathering steels, having increased atmospheric corrosion resistance, or
- those products rolled on a plate mill.
