S355K2G3 is a structural steel grade typically used in the manufacture of bridges, large structures and heavy equipment. It has a minimum yield strength of 355 MPa and a tensile strength of 470 - 630 MPa. It is a non-alloyed structural steel grade, which means it has excellent weldability and is well suited to use in the manufacture of bridges and large, heavy equipment.
The properties of S355K2G3 make it suitable for use in the fabrication of structural parts, such as beams, columns, heavy member support plates, and complex fabricated welded structures. It is also used in elevated temperature applications such as pressure vessels and piston supports, as well as in the manufacture of heavy duty agricultural machinery.
Other applications where S355K2G3 is commonly used include bridges and quay walls, water retaining structures, and engineering works for railway or highway construction. The steel is also suitable for use in machine components subject to wear, such as shafts, pulleys, spindles, conveyor rollers, drive gears, and support structures.
S355K2G3 is a popular choice for transportation industries due to its high strength and excellent weldability. It is also used in the production of shipbuilding components and other applications that require great deal of strength and ductility. Its low temperature toughness and weldability also make S355K2G3 well suited for cold formed components in bridge construction.
S355K2G3 is also suitable for use in mining operations due to its ability to withstand heavy loads and environmental stress. It is ideal for use in mining equipment such as jumbo drills, crushers, draglines, and rock cutters. The steel is also used in the fabrication of pressure vessels, rock support plates, and slurry tanks used in mining operations.
S355K2G3 has a wide variety of applications and is suitable for a range of industries and sectors. Its unique combination of strength, ductility, and weldability make it an ideal choice for many structural and heavy-duty applications. Furthermore, its superior corrosion resistance make it a great choice for maritime and power generation industries.
