According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for A514 grade M alloy steel plate, 42CrMo steel is quenching and tempering.
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 A514 grade M alloy steel plate etc. steel material.
By Region: data shows that in the first quarter of Asia, crude steel A514 grade M alloy steel plate production was 315.2 million tons, down 0.3% year on year. Crude steel production in the EU region in the first quarter was 38.3 million tons, down 10.0% year on year. The output of crude steel in North America in the first quarter was 29.5 million tons, down 4.0% year on year. According to the output ranking, according to the latest data of the A514 grade M alloy steel plate world iron and Steel Association, the output of crude steel in the top ten countries in March 2020 was 126 million tons (85.71% of the world), and the output of crude steel in the first quarter was 376 million tons (85.07% of the world).
The company regularly holds sales elites to share experiences, to promote the rapid growth of colleagues, and achieve the company and employees. The company conducts employee skill training and related knowledge video learning from time to time. All these things is to improve the employees' skills and literacy, and reflects its own value. It has always been the pursuit of BBN steel to enhance the employee’s ability and keep up with the times.
The largest crane in the world, the SGC-250, uses the power of A514 grade M alloy steel 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.
