Products Description
S355J2 is a European standard hot-rolled structural steel product, belonging to the European standard low-alloy high-strength structural steel plate. Its implementation standard is EN10025 special technical conditions. There are two ways to express S355J2 steel plate, respectively: S355J2+N= normal rolling -20 ° C impact, S355J2=-20 ° C impact.
The chemical composition of S355J2 mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P) and sulfur (S). The specific ingredients are as follows:
- Carbon content (C) : usually below 0.20%.
Silicon content (Si) : usually below 0.55%.
- Manganese content (Mn) : usually below 1.60%.
- Phosphorus content (P) : usually below 0.025%.
- Sulfur content (S) : usually below 0.025%.
The excellent mechanical properties of S355J2 make it a widely used structural steel material. The main mechanical property parameters of S355J2 are as follows:
- Tensile Strength: up to 510-680 MPa.
- Yield Strength: up to 355 MPa.
- Elongation (Elongation) : at 25 mm scale, the minimum is 20%.
Impact Toughness: Impact toughness is 27 joules (J) at the lowest temperature.
S355J2 is a commonly used structural steel material with excellent mechanical properties and weldability. Its composition contains elements such as carbon, silicon, manganese, phosphorus, and sulfur, and may contain small amounts of other alloying elements. The S355J2 is widely used in construction, Bridges, machinery, ships and other fields, and is favored for its high strength and durability. When using S355J2 for welding, you need to select proper welding methods and parameters to ensure the welding quality.
