Forecast of A588 Grade K properties import and export of China

The effect of nitrogen (N) on the properties of A588 Grade K 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 A588 Grade K properties and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

The ability to resist plastic deformation and fracture under the action of external load is called A588 Grade K properties strength, and the local resistance of solid materials to external objects such as indentation and scribing is hardness. In the mechanical properties of weathering steel, strength and hardness are related indexes, while plasticity (elongation, reduction of area) and toughness (impact value) are related indexes.
