GB / T1591 Q345D steel is a commonly used low alloy plate in China. It is equivalent to grade S355J2 in Germany and ASTM A529MGr50 in the United States, with slightly different chemical composition and the same mechanical properties. Under normal delivery conditions, SMA570W seaport buildings used steel, Q345D steel equivalent to S355J2G3 in European standard, and even almost the same performance as the S355J2G4. They can be used interchangeably.

Main SMA570W seaport buildings used steel production plants: Wugang, Baosteel, Laiwu Steel, Angang, Baotou Steel, BBN Steel, Katalor Industry
Pressure vessel plates are used to manufacture steel plates for steam boilers, pressure vessels and other pressure vessel structures. Because this kind of steel plate is subjected to certain air pressure and water pressure, and the use environment of different temperatures, such as high, medium and low temperature, etc., the requirements for this kind of steel plate are relatively strict.

During the welding of hardfacing wear-resistant steel plate, SMA570W seaport buildings used steel, the welding shall be carried out in strict accordance with the drawing, welding process and relevant standards. Follow the welding sequence of first welding the base layer, then welding the transition layer, and then welding the multiple layer. In order to prevent adhesion of welding spatter, anti spatter coating should be applied within 100 mm on both sides of groove of stainless steel clad plate before welding.
