Performance analysis of S355G8+N steel plate

The marine engineering steel is suitable for various complex working conditions and harsh natural environment, and the service period is 50% higher than that of the ordinary ship steel. Therefore, the S355G8+N marine engineering steel is required not only to have high strength and high plasticity, good welding performance and seawater resistance, erosion properties, but also good toughness to ensure that steel and equipment can adapt to various loads and low temperature environments.

The surface of the S355G8+N steel plate shall be 100% inspected by the naked eye.
Internal quality of S355G8+N steel plate: The material must be reliable and free from internal defects that may hinder the purpose of the application.

All S355G8+N steel plates shall be ultrasonically tested according to EN 10160; ultrasonic testing can be performed before or after final heat treatment.
