The largest crane in the world, the SGC-250, uses the power of A572 grade 55 CS steel carbon plate, high-strength steel to deliver unprecedented lifting capacity. Designed and built by Belgium-based heavy lifting powerhouse Sarens, it is called the SGC-250 – or, to use its nickname, 'Big Carl'. The ring-based crane, the first of Sarens' third generation of ring cranes, is now being put to work in its first project at the Hinkley Point C nuclear power plant in the UK. This crane is capable of lifting the weight of eight planes, or 563 elephants.
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 A572 grade 55 CS steel carbon plate 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.
The A572 grade 55 CS steel carbon plate, medium and heavy steel plate can be processed for secondary processing. If the medium and heavy steel plates are not used later, the factory can process it into other plates, which will not waste resources and save cost. The overall market situation of A572 grade 55 CS steel carbon plate, medium and heavy steel plate is unstable, and the price changes every day. If the overall price rises, you can first observe for a period of time to find out why it has risen, and you can wait until the best price to buy.
A572 grade 55 CS steel carbon plate stock increased rapidly. The social stock of five kinds of steel products (screw steel, wire rod, hot rolled coil, cold rolled coil and medium and heavy plate) in major cities in China was 8.12 million tons at the end of January and 19.05 million tons at the end of February. By the middle of March, the social inventory was 20 million tons, an increase of 13.18 million tons or 193.3% over the end of December last year.
