Q355ND High Strength Low Alloy Structural Steel
Q355ND hsla steel is a low alloy high strength structural steel. Q355ND high strength low alloy steel plate is not only high strength steel, it is also low carbon steel.
Q355ND hsla structural steel has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion resistance and certain wear resistance.
Q355ND low alloy steel plates delivery status: The steel is delivered in hot-rolled, normalized, normalized rolling or thermo-mechanical rolling (TMCP) condition.
Q355ND low alloy structural steel is generally used in power towers, various lifting cranes, heavy-duty vehicles, oil derricks, high-temperature fans, large electric shovels, dump trucks and drilling rigs, coal mine hydraulic supports, steel structures, etc.
