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 A514 Gr B quenched and tempered steel 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 business department is mainly responsible for communicating with customers, from the manufacturing of steel plates, steel pipes and other products, knowing customers' needs and processing conditions, etc. within the time agreed with customers, the delivery time is short, the price is the most competitive, and the service is the best. Their responsibilities are to deal with customer consultation, solve customer problems, update production plans, and instruct the logistics department to deliver products to customers.
The yield strength of A36, D36, E36 and F36 is not less than 355N/mm^2, and the A514 Gr B quenched and tempered steel tensile strength is 490~620N/mm^2. A, D, E and F respectively indicate that they can be at 0° and -20 ° respectively. Impact toughness that can be achieved at -40℃, -60 ℃.
20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. A514 Gr B quenched and tempered steel, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
our company supplied 2300 ton API 5L GrB ERW pipe to Petroleum company in 2016. It takes 35 days for our company to finish all the production according to API 5L standard. The products are used to drilling , gas transmission works. And we supply the API5L PSL1 GR B original Mill Test Certificate, API5L PSL1 GR B pipes picture, the dimension test, the A514 Gr B quenched and tempered steel material, heat number, supplier name and size will be shown on the surface of steel pipe.
For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate A514 Gr B quenched and tempered steel EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
