Brief introduction:
S355 steel is a type of structural steel with good weldability, moderate toughness, and high strength, making it suitable for various applications like construction, bridges, wind turbines, and heavy machinery. It’s a low-carbon manganese steel, often supplied as plates, bars, or sections, and is typically hot-rolled. Types of S355 Steel:
S355JR: A common grade with a specified impact energy of 27J at +20°C.
S355J0: A grade with a specified impact energy of 27J at 0°C.
S355J2: A grade with a specified impact energy of 27J at -20°C.
S355K2: A grade with a specified impact energy of 40J at -20°C.
Application:
Construction: Used in the construction of buildings, bridges, and other infrastructure.
Heavy Machinery: Used in the manufacturing of heavy machinery and equipment.
Wind Turbines: Used in the construction of wind turbine towers and other components.
Offshore Industry: Used in offshore structures and equipment.
