Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, EN S460ML steel plates based on a high starting point and high technology, the company has vigorously developed various steel products EN S460ML steel plates and deep-processed parts, steel structures, precision castings, seamless pipes.
Strip steel is mainly used for the manufacture of welded pipes, clamps, washers, spring blades, saw blades, blades and other fields, so the EN S460ML steel plates, strip steel specifications are also relatively standardized. First, the strip width should be within 1300mm, if it is too wide, it will become a steel plate, and the machining is not allowed to be too wide, otherwise it will fail. Second, the strip steel length is not limited, and the strip steel can be coiled together after bending, reducing most of the space.
20# steel is carbon steel with carbon content of about 0.20%. It belongs to low carbon steel with high quality. The equivalent material of 20# steel is S20C. 20# steel has low strength and hardness, good plasticity and toughness, good carburizing effect and good weldability. 20# steel is often used to make pressure parts (such as gasket, chain piece), carburizing parts (gear, CAM), welding parts, plastic mold, etc.
After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the EN S460ML steel plates plate should be derusted before cutting.
"A283C is same as A283 Gr C, A283 grade C. A283C plate technical parameters: A283C plate chemical composition - max. 0.24% carbon, max. 0.40% silicon, max. 0.90% manganese, max. 0.035% phosphorus, max. 0.040% sulphuric, and min. 0.20% Cu. A283C plate mechanical properties: min. yield strength is 205 MPa, tensile strength is 380-515MPa, min. elongation is 22% in 8"" and 25% in 2"". Tolerance of A283C plate is subject to ASTM A6. The density of EN S460ML steel plates, A283C plate is 7.85g/cm3."
