Structural steel is a category of steel construction material that is produced with a particular cross section or shape, and some specified values of strength and chemical composition. A572 Gr 55 high strength steel, Structural steel plates are normally supplied in the as-rolled condition. Our structural steel plate are supplied with thickness range 3mm to 350mm. The plates may be ordered normalized or stress relieved, or both. steel plates shall be normalized. steel plates and sheets shall be quenched and tempered.
Q460D elongation: not less than 17%.Q460D impact test: 0℃ impact test: not less than 34J.Q460D is mainly used in the manufacture of high strength construction machinery and hydraulic support. A572 Gr 55 high strength steel, Q460D has good toughness, plasticity and cold stamping properties and is widely used.
The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy A572 Gr 55 high strength steel products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of A572 Gr 55 high strength steel stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.
After extrusion, the A572 Gr 55 high strength steel 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.
