Phosphorus is a very harmful element in steel plate NM500 manufacture price steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of steel plate NM500 manufacture price 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.
In the past 10 years, domestically-made offshore platform steel has been widely adopted in China's offshore oil projects, and offshore platform steel has gradually developed in the direction of high strength. Relevant data show that the pile legs, pile boots, cantilever beams and other key parts of the jack-up platform require high load. In order to improve the stability of the hull during towing after floating, it needs to be lightweight, and high-strength steel plates must be used.
