Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of S690QL pdf etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in S690QL pdf etc. steel is strictly controlled.
