S355K2 H-Beam Hot-Rolled Steel

When manufactured as H-profiles, the S355K2 grade offered by GNEE is particularly suitable for applications where material with enhanced low temperature toughness is required, making it ideal for use in a variety of outdoor structures exposed to adverse weather conditions.

The "S" in S355K2 hot-rolled profile stands for structural steel, "355" refers to the minimum yield strength in MPa for a nominal thickness of up to 16 mm, and "K2" refers to the impact energy requirement of the steel at -20°C, at which the impact energy is at least 40 joules.

Key features of S355K2 hot-rolled steel
Yield strength: Minimum yield strength of 355 MPa for material thickness up to 16 mm.
Tensile strength: Typically between 470 and 630 MPa, depending on the specification and product form required by the customer.
Impact test requirements: At least 40 joules of impact energy is required at -20°C, suitable for applications that require high toughness at low temperatures.

Chemical composition: Includes elements such as carbon, manganese, phosphorus, sulfur, silicon, and other alloying elements added in specific proportions according to standard specifications to ensure mechanical properties.

Advantages of S355K2 H-beam: High load-bearing capacity; excellent weldability; good formability; enhanced toughness at low temperatures (-20°C), very suitable for structures in cold environments; improved performance in severe weather conditions and reduced maintenance requirements.
