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 P235GH chemical composition 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 p235gh chemical composition etc. steel is strictly controlled.

Delivery status of P355NL2 steel plates, p235gh chemical composition:A. Normally, the P355NL2 steel plates are delivered in normalized state. According to the negotiation between the supplier and the demander, normalizing rolling can be used instead of normalizing. In this case, the samples should be simulated normalizing according to the agreed test frequency to verify that the performance meets the requirements.B.
