Phosphorus is a very harmful element in quality SA588 Grade A steel steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of quality SA588 Grade A steel steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
