Product Introduction

Rolled Nm550 armored ballistic steel plate

processability

Whether you can use this steel plate to process a trustworthy product fundamentally depends on the entire processing process and the technology used in the processing.

When processing, it should be ensured that the calculation, design and processing methods meet the requirements of the material itself, meet the requirements of the current relatively new processing technology, and meet the requirements of the actual use of the product in the future. The customer should choose the appropriate material, taking into account the high strength and hardenability, while referring to the recommendations of EN 1011. Cold forming

The NM550 can be cold-formed despite its high hardness. However, it should be noted that with the increase of yield strength, the deformation force and resilience required for steel plates of the same thickness should also be increased. It is recommended to sand the flame cutting edge or cut edge of the cold bending area to prevent cracking.
