P460NH steel is a normalized weldable fine grain steel. Executive standard: EN10028-3, steel number: 1.8935. P460NH steel is alloy special steel for shipbuilding use GL-D hull structural steel pressure equipment. P460NH steel has good plasticity, toughness, cold bending performance and welding performance. P460NH steel plates are usually delivered in normalized condition. According to the negotiation between the supplier and the buyer, normalizing rolling can be used instead of normalizing. In this case, the sample shall be subject to simulated normalizing according to the agreed test frequency to verify that the performance meets the requirements.
The company adheres to the shipbuilding use GL-D hull structural steel business tenet of "integrity casting strength, cooperation creating win-win", takes value-added service of supply chain as the tenet, and under the premise of existing market, bulk trade, logistics distribution and other advantages, develops a new comprehensive steel industry model combined with informatization. And will continue to provide customers with high-quality steel products and good service. We sincerely welcome new and old customers to join hands with our company shipbuilding use GL-D hull structural steel and seek common development!
At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick shipbuilding use GL-D hull structural steel steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.
Manganese steel plate is a kind of common steel, which is a kind of high-strength anti manganese steel. shipbuilding use GL-D hull structural steel, Manganese steel plate is mainly used to bear the impact, extrusion, material wear and other severe working conditions. It is a typical anti-wear steel, with austenite and carbide as cast structure. After water quenching at about 1000 ° C, the structure changes into single austenite or austenite with a small amount of carbide.
The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
