Spanish alloy structural steel is a kind of structural steel produced in Spain and has good impact resistance, weldability, and good plasticity. The alloy content is mainly composed of manganese, chromium, molybdenum and phosphorus, sulfur, and copper. These alloy components can improve the strength, toughness and plasticity of the steel. Spanish alloy structural steels mainly include steel grades S235, S275 and S355. Each grade has different strength levels, with S235 having the lowest strength and S355 having the highest.
S235 is typically used in bridges, buildings, and other constructions that require high strength, low weight, and good weldability. It is also used for making components for wind power and shipbuilding industries due to its excellent corrosion resistance. In addition, S235 can also be used for making earthmoving equipment, hoisting machinery and construction machinery parts.
S275 is a mid-strength steel, with a slightly higher strength than S235 and a better ductility. It is mainly used for making tanks, pipelines, conveyor systems and other machinery parts. In addition, it is also used in construction and bridge engineering due to its excellent resistance to corrosion, fatigue and impact.
Finally, S355 is a high-strength steel that has the highest strength level compared to the other two grades. It is mainly used in bridges, large-scale buildings and other construction projects requiring extreme strength and impact resistance. In addition, this steel is also used in cases where high plasticity is required.
In conclusion, Spanish alloy structural steel is of great importance in many industries due to its excellent properties, such as high strength, excellent ductility and corrosion resistance. These properties make it suitable for many applications in multiple industries.
