Q355NE is a low-alloy high-strength steel, where "Q" means yield strength. 355 means that the yield strength of this steel is 355MPa. Q355A grade is not subject to impact; Q355B grade is impact at 20 degrees at room temperature; Q355C grade is 0 degrees Impact; Q355D level, it is a -20 degree impact; Q355E level, it is a -40 degree impact. When the steel plate is required to have thickness-direction properties, a symbol representing the thickness-direction (Z-direction) performance level is added to the steel grade, for example: Q345EZ15. When heat treatment requirements are required, such as normalizing, the steel grade will be suffixed with N, often represented by +N, for example: Q345E+N.
Q355NE steel plate itself not only has high strength, but also has certain comprehensive high-quality properties such as toughness, fatigue resistance, impact resistance, corrosion resistance, low temperature impact resistance, welding and easy processing.
Application scope of Q355NE steel plate: commonly used in mining machinery, metallurgical machinery, engineering machinery, shipbuilding, large sensing plants, bridges, high-rise buildings, thermal power plants, nuclear power projects. At the same time, Q355ND, Q355NC, and Q355NE steel are also designated steel plate materials for wind power project reels. , steel plates are also often used in ordinary wear-resistant materials and wear-resistant parts with non-special requirements.
