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 A514 grade R alloy steel plate 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 A514 grade R alloy steel plate materials and specifications can be ordered in advance.
In terms of steel for offshore platforms, steel also plays an important supporting role. Because the offshore platform is immersed in sea water for a long time, it also needs to withstand the test of various harsh sea conditions such as storms, waves, glaciers, etc. Therefore, the steel A514 grade R alloy steel plate for offshore platforms requires not only high strength, but also good corrosion resistance, low temperature toughness and resistance, lamellar tearing performance, etc.
The thickness of cold-rolled steel sheets is generally relatively small, and the thickness of hot-rolled plates can be larger. The surface quality, appearance, and dimensional accuracy of cold-rolled steel sheets are better than those of hot-rolled plates, and the thickness of cold-rolled steel sheets can be rolled as thin as about 0.18mm. A514 grade R alloy steel plate, Hot-rolled plates has high strength, good toughness, easy processing and good weldability and other excellent properties.
Processing performance of quenched and tempered steel: A514 grade R alloy steel plate plate can be used for cold working, bending and cutting. When the gas is cut off, cracks will not occur even without preheating. When preheating processing, quenched and tempered steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: Because it contains alloy elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.
S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. A514 grade R alloy steel plate, S355J2+N low alloy steel plate is widely used in bridges, vehicles, ships, building steel structures.
