Flat steel is divided into galvanized flat steel, carbon flat steel, stainless steel flat steel, etc. according to the material. Flat steel can be divided into hot-rolled flat steel and forged flat steel according to the forging process. SA516 Grade 70 carbon steel boiler sheet, Hot-rolled flat steel is a potential-rolled long steel with a rectangular cross-section for general use. Forged flat steel is a long steel plate with a rectangular cross section that is forged. Hot-rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery. The thickness of the flat steel is 8-50mm, the width is 150-625mm, and the length is 5-15m.
SA516 Grade 70 carbon steel boiler sheet, Q890E steel plate is a kind of quenched and tempered steel plate for high strength structure, in which "Q" means yield, "890" means yield value, "E" means grade level. Q890E steel is equivalent to EN grade S890QL.Executive standard of Q890E steel plate: GB / T 16270.Q890E steel plate delivery status (heat treatment): quenching and tempering.The size, shape, weight and allowable deviation of Q890E steel plate shall comply with GB / T709.
