Medium and heavy plate is widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields. The surface quality of medium and heavy plate mainly refers to its surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plate. The surface quality of S500QL steel, medium and heavy plate not only affects the appearance of the products, but also reduces the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate.

Q460C steel plate executive standard: GB / T1591 low alloy high strength structural steel standard and GB / T16270 high strength structural quenched and tempered steel plate standard.S500QL steel, Q460C steel plate smelting method: the steel is smelted by converter or electric furnace, and can be refined outside the furnace if necessary. Unless the demander has special requirements and indicated in the contract, the smelting method is generally selected by the supplier.

There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products S500QL steel are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.
