S275JR vs S355JR Material characteristics
S275JR h section steel chemical composition
Carbon (C) Less than or equal to {{0}}.22%, manganese (Mn) Less than or equal to 1.50%, phosphorus (P) Less than or equal to 0.035%, sulfur (S) Less than or equal to 0.035%; aluminum deoxidation process refines grains and improves plasticity.
S355JR chemical composition
Carbon (C) Less than or equal to {{0}}.24%, manganese (Mn) Less than or equal to 1.60%, phosphorus/sulfur (P/S) Less than or equal to 0.035%; trace amounts of niobium (Nb) or vanadium (V) are added to strengthen the grain structure.
S275JR h shaped steel: Greater than or equal to 275 MPa (when thickness Less than or equal to 16mm);
S355JR h beam structure: Greater than or equal to 355 MPa (when thickness Less than or equal to 16mm).
S275JR h section beam: 450~630 MPa;
S355JR structural h beam: 470~630 MPa.
S275JR h beam material: -20 degree impact energy Greater than or equal to 27 J;
S355JR h shaped beam: -20 degree impact energy Greater than or equal to 40 J (better than S275JR).
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.
