The cold rolling precision bright pipe system produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. The inner hole of A131 grade D ship repairing steel steel pipe can be divided into round, spline and plum blossom, which is widely used in automobile, motorcycle, electric power, petrochemical, ship, aerospace, bearing, pneumatic components, oil cylinder, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special A131 grade D ship repairing steel materials and specifications can be ordered in advance.
15Mo3 heat resistant steel plate for boiler and pressure vessel executive standard: DIN1715515Mo3 heat resistant steel plate delivery status: normally delivered in normalized status. According to the special agreement at the time of ordering, 15Mo3 heat resistant steel plate also be delivered in non processed status.15Mo3 heat resistant steel plate is mainly used for steam boiler equipment, A131 grade D ship repairing steel, pressure vessels, large pressure pipes, drum manufacturing of utility boilers and similar components.
Common carbon killed steel plates are steel plates made by hot-rolling ordinary carbon structural steel killed billets. The advantage of A131 grade D ship repairing steel, killed steel is that the chemical composition is uniform, so the mechanical properties of each part are also uniform, the welding performance and plasticity are good, and the corrosion resistance is strong. Common killed steel plates are mainly used to produce components that withstand impact at low temperatures, welded structures and other structural parts that require higher strength.
A131 grade D ship repairing steel controlled rolling is that, on the basis of adjusting the chemical composition of A131 grade D ship repairing steel, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of A131 grade D ship repairing steel.
A131 grade D ship repairing steel, Q355GNH weather resistant steel plate is one of our main product, it is belong to the weather resistant steel plate. We can supply the different sizes of Q355GNH weather resistant steel plate. And the rolling size of Q355GNH weather resistant steel plate is following: the thickness range is 1.2-150mm, the width range is 1220-4200mm, and the length range is 5000-18000mm.
