Phosphorus is a very harmful element in ASTM A588 heavy plate steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of ASTM A588 heavy plate 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.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the ASTM A588 heavy plate steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its ASTM A588 heavy plate steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
The ASTM A588 heavy plate, medium and heavy steel plate can be processed for secondary processing. If the medium and heavy steel plates are not used later, the factory can process it into other plates, which will not waste resources and save cost. The overall market situation of ASTM A588 heavy plate, medium and heavy steel plate is unstable, and the price changes every day. If the overall price rises, you can first observe for a period of time to find out why it has risen, and you can wait until the best price to buy.
