Normal strength shipbuilding structural steel is divided into four grades: A, B, C, and D. The yield strength (not less than 235N/mm^2) of P355GH material these four grades is the same as the tensile strength (400~520N/mm^2). However, the impact properties of steel plates at different temperatures are different.

The clad steel plate is based on carbon structural steel, which is sprayed with stainless acid resistant and heat-resistant steel on the surface. The clad steel plate is widely used to make acid and alkali resistant container. Advantages of clad steel plate: The appearance of the clad steel plate is very smooth, the quality is very good, and it will not rust. Disadvantages of clad steel plate: the p355gh material, clad steel plate has better requirements for production technology and are more expensive.

Try to use p355gh material high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the p355gh material temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
