ASTM A537 steel is a heat-treated carbon silicon manganese steel plate for ASTM pressure vessels, which is divided into 3 levels A537 CL1, A537 CL2, A537 CL3. S235JR welded construction, A537 CL1 plates delivery status: normalizing; When the A537 CL1 plate thickness is ≤65mm, the yield strength is ≥345MPa, and the tensile strength is ≥485MPa. When the thickness is 65 - 100mm, the yield strength is ≥310MPa and the tensile strength is ≥450MPa.
It is easy to confuse ship plate with ordinary steel plate. What are the differences between ship plate and ordinary steel plate? First, compared with the ordinary steel plate, the thickness of the ship plate is thicker and the accuracy is better. Otherwise, it will be broken by the impact of sea water during the operation, which will bring life danger to the personnel on the ship. Second, compared with ordinary steel plate, S235JR welded construction, the corrosion resistance of ship plate is more outstanding. The ship is immersed in sea water for a long time, if it does not have good corrosion resistance, then the ship plate will rust easily, and the weight of the ship will become larger, and it will also bring pollution to the sea water and cause ecological damage.
The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in S235JR welded construction etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.
