1.0570, DIN St52-3N, S355J2G3

GENERAL CHARACTERISTICS

This grade of steel is carbon manganese, high yield non alloy steel. It is called S355 because of the average minimum yield for this material is 355 Mpa. As a structural steel, it has excellent strength and weldability. It can be readily welded to other weldable steel. For its low carbon equivalent, it possesses good cold-forming properties. S355J2G3 is generally supplied in a normalized condition.

    Description Unalloyed structural steel. Applications Common structural steel for welded assemblies, Re>355 N/mm2. Guaranteed toughness at 0 oC. It can be used for statically and dynamically stressed constructions. Physical properties (average values) at ambient temperature Modulus of elasticity [103 x N/mm2]: 210 Density [g/cm3]: 7.80 Soft Annealing Heat to 650-700oC, cool slowly. Hardening Harden from a temperature of 860-890oC followed by oil or water quenching. Tempering Normalizing temperature: 860-890oC. Forging Hot forming temperature: 1050-850oC. Machinability Machinability is good, rated at 90% that of the 1112 alloy used as a 100% machining rated steel.
