Free cutting hardox 400 mechanical properties mechanical properties

Experiments have proved that the outstanding feature of the precipitation-strengthened HARDOX 400 mechanical properties, wear-resistant plate in terms of mechanical properties is that the yield strength is greatly improved. For example, the yield strength of the wear-resistant plate after precipitation strengthening treatment reaches 480-8l0MPa, and the yield strength ratio is 0.55-0.56; the wear-resistant plate that uses molybdenum, vanadium, and iron composite alloying, the yield ratio after dispersion strengthening is 0.60- 0.65.

The effect of nitrogen (N) on the properties of HARDOX 400 mechanical properties and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in HARDOX 400 mechanical properties and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
