Effect of laser welding technology on weld microstructure of SA588 grade B carbon steel plate sheet

The company breaks through the production limit of ultra-wide pressure vessel steel plates and can provide ultra-wide CrMo steel plates for pressure vessels over 5 meters. This breakthrough not only upgrades the manufacturing capacity of ultra-wide SA588 grade B carbon steel plate sheet steel plates, but also greatly improves the safety of petrochemical refining pipelines, promotes the development of petrochemical industry equipment, and promotes the high-end manufacturing of ultra-wide pressure vessel CrMo steel plates.

The company has a mature technical team whose reponsibility is to design the drawing, choose suitable material and evaluate the whole production processaccording to customers’ requirement. The company is led by talents and technology, and comprehensively promotes its six business segments like steel material supply, precision steel casting, environmental protection equipment, household appliance, SA588 grade B carbon steel plate sheet steel structures and oil tank projects. Seeking new developments in new technology and business areas, and fostering a large number of industry-leading, international-level projects.

The quality of carbon steel is distinguished by the amount of sulfur (s) and phosphorus (P) in the steel. When the SA588 grade B carbon steel plate sheet sulfur content in carbon steel is not more than 0.050% and the phosphorus content is not more than 0.045%, it is ordinary carbon steel; when the sulfur content and phosphorus content in carbon steel are less than 0.040%, it is high-quality carbon steel; when the SA588 grade B carbon steel plate sheet sulfur content in carbon steel is less than 0.030% and the phosphorus content is less than 0.035%, it is high-quality carbon steel.

SA588 grade B carbon steel plate sheet, 27SiMn material has high strength and wear resistance, high hardenability, medium plasticity during cold deformation, good machinability and fair weldability. It is mostly used after quenching and tempering, and can also be used in normalizing or hot rolling state. 27SiMn material chemical elements: C: 0.24-0.32, Si: 1.10-1.40, Mn: 1.10-1.40. 27SiMn material mechanical properties: tensile strength 980 MPa; yield strength: 835 MPa; elongation after fracture: 12%; impact energy: 39J. 27SiMn material can be used to make hot stamping parts with high toughness and high wear resistance, which do not need heat treatment or normalizing, such as tractor track pins.

Good news: The largest steel importer in Nigeria ordered 4068 tons API 5L X52Q PSL2 3LPE seamless pipes and also ordered 8 pcs 42699.6 m³big diameter Crude oil storage doom roof tank in A537CL2 steel grade. In Sep 2019, This Nigeria client visited our company and factory, they were very satisfied with our company's quality control,production capacity and service. We also have reached a agreement for Phase II Project, It is also with another 10,000 tons APl 5L X52Q PSL2 3LPE seamless pipes.
