S355K2
1.0596Structural steel with guaranteed Charpy impact at -20°C (KV ≥40J). Same strength as S355J2 (ReH ≥355 MPa) but higher toughness: K2 = 40J at -20°C vs J2 = 27J at -20°C. Used for bridges, crane structures, offshore platforms, and welded structures in cold climates where fracture toughness at low temperature is critical.
