What does steel S460N stand for? the letter S is short for Structural steel. The number 460 stand for the minimum yield strength is 460MPa for S460N steel. The character N is for Normalised rolling when produce in mill. For steel plates S460N, our minimum order quantity shall be above 10 tons for each thickness. For A573 grade 70 plate, S460N hot rolled steel plate specification available, our plate thickness ranges from 8mm to 200mm.
In recent years, in line with the development trend of iron and A573 grade 70 plate steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which A573 grade 70 plate are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of A573 grade 70 plate high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Anshan Iron and Steel's 4300 mm rolling mill, Shagang's 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's A573 grade 70 plate technical equipment.
After extrusion, the A573 grade 70 plate tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.
To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent A573 grade 70 plate products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the A573 grade 70 plate technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
