NP550 high strength steel plate cutting

There are many kinds of NP550 high-strength steel plate thickness, which mainly depends on the application field.
At present, the thickness of civil steel plate is mainly between 2.0-3.0mm.
Military in thickness of 3.0-25mm,
The thickness of the protective steel plate is mainly 4.0-10mm.

The NP5550 steel plate adopts a unique chemical composition design and process path, while ensuring excellent performance, and because of the use of a unique quenching process, when the thermal cutting temperature of the NP550 steel plate exceeds 200-250°C, the mechanical properties of the steel plate will change. The hardness decreases, resulting in a decrease in the protective effect of the steel plate.

The best way to eliminate the reduction of hardness is cold working, such as water jet cutting or wire cutting, but the actual production and processing of large parts are generally small parts with high requirements. However, considering the efficiency and cost of production, conventionally, ion or laser cutting is generally selected.
