P355NL1 steel tensile strength Rm:630-450MPa.If high demands are made on notch impact strength and aging resistance. It is mainly used in steam boiler and pressure vessel construction. RD 40 shipbuilding marine grade steel plate, P355NL1 plates can be processed with all known welding methods. Welding is possible both with the machine and by hand. Preheating is usually not necessary unless the outside temperature is below 5°C. Then preheating to about 150°C is recommended.
Common carbon killed steel plates are steel plates made by hot-rolling ordinary carbon structural steel killed billets. The advantage of RD 40 shipbuilding marine grade steel plate, 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.
The pre cooling direct quenching and low temperature tempering of wear-resistant composite plate can reduce the quenching deformation of the workpiece, and the residual austenite content in the carburized layer can also be slightly reduced. The surface hardness of the hardfacing wear-resistant composite plate, RD 40 shipbuilding marine grade steel plate is slightly increased, but the austenite grain does not change. It is widely used in various tools of fine grain steel manufacturing.
The alloy steel plate is among our business scope, and it is one of our main product. If you have any demands or questions about alloy steel plate, such as 34CrMo4 RD 40 shipbuilding marine grade steel plate material properties, 42CrMo4 AISI equivalent, 12Cr1MoV equivalent ASTM, 40Cr material specification, 42CrMo hardness, 50CrMo4 chemical composition and so on, please free free to communicate with us. We have professional technical team and sales team, who will give you RD 40 shipbuilding marine grade steel plate professional answers and quotation about alloy steel plate in time.
The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
