SA516Gr60 meets the requirements of (ASME) ASTMA516/A516M standards, and meets the needs of oil gas with high content of sulfur and hydrogen, reducing sulfur and hydrogen corrosion, reducing equipment maintenance, and increasing equipment life. The steel S 550 MC, QStE460TM high yield strength steel has the following characteristics: good impact resistance, low temperature deformation, good welding performance, good fatigue resistance, good anti-layer cracking performance, microalloying, high purity, low carbon equivalent, and strong resistance to sulfur and hydrogen.

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, S 550 MC, QStE460TM high yield strength steel, 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.

With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of S 550 MC, QStE460TM high yield strength steel etc. steel material.
