How much is the marine steel per ton?According to the difference of quality grade and strength grade, as well as the difference of plate size, production area, and user requirement, the price of A514 Gr P structural steel plate fluctuates greatly. At present, the market price of marine plate is about 3800 yuan per ton to 5800 yuan per ton. Generally, the most commonly used marine plate price is about 4000 yuan per ton.
Because A514 Gr P structural steel, boiler steel plate is a product of important use, the safety and reliability requirements are strict, and the manufacturing technology is difficult. The boiler steel plate material must have the following main characteristics:The boiler steel plate has high yield strength performance in a certain temperature range (medium temperature and high temperature);The boiler steel plate has sufficient toughness, no brittle failure accident will occur during manufacturing or use.
During cladding welding of hardfacing wear-resistant steel plate, A514 Gr P structural steel, preheating and slow cooling should not be adopted. Sometimes, forced cooling measures are even taken to reduce the residence time of weld in the temperature range of 400-850℃ to prevent local chromium deficiency in austenite grain boundary and σ brittle phase in the plate, resulting in 475℃ brittleness, so as to ensure that the weld metal has good mechanical properties and intergranular corrosion resistance.
Difference between Q235A steel and Q235B steel plates: in the national standard GB700, the difference between A514 Gr P structural steel, Q235A steel and Q235B steel plates is mainly in the carbon content. In addition, Q235A steel plate does not do impact test, while Q235B Q235B steel plates need normal temperature impact test, V-notch. Relatively speaking, the mechanical properties of Q235B steel plates are better than that of Q235A steel plate.
