S275JR vs S355JR Material characteristics
S275JR h section steel chemical composition
Carbon (C) ≤0.22%, manganese (Mn) ≤1.50%, phosphorus (P) ≤0.035%, sulfur (S) ≤0.035%; aluminum deoxidation process refines grains and improves plasticity.
S355JR chemical composition
Carbon (C) ≤0.24%, manganese (Mn) ≤1.60%, phosphorus/sulfur (P/S) ≤0.035%; trace amounts of niobium (Nb) or vanadium (V) are added to strengthen the grain structure.
Yield strength
S275JR h shaped steel: ≥275 MPa (when thickness ≤16mm);
S355JR h beam structure: ≥355 MPa (when thickness ≤16mm).
Tensile strength
S275JR h section beam: 450~630 MPa;
S355JR structural h beam: 470~630 MPa.
Low temperature toughness
S275JR h beam material: -20℃ impact energy ≥27 J;
S355JR h shaped beam: -20℃ impact energy ≥40 J (better than S275JR).
Processing performance
S275JR h beam steel structure: excellent welding performance, suitable for complex welding structures;
S355JR h section steel beam: welding heat input needs to be controlled to avoid embrittlement of the heat affected zone, but supports high strength connection.
