S355J2H Pipe 1. Introduction S355J2H is a non-alloy structural steel grade specified under EN 10210 standards. The 'S' denotes structural steel, '355' indicates the minimum yield strength (355 MPa), 'J2' signifies impact energy tested at -20°C, and 'H' indicates it is a hollow section. These pipes are widely used for structural applications due to their strength, toughness, and weldability. 2. Chemical Composition The typical chemical composition of S355J2H steel is as follows: Element Content (%) Carbon (C) ≤ 0.22 Silicon (Si) ≤ 0.55 Manganese (Mn) ≤ 1.60 Phosphorus (P) ≤ 0.03 Sulfur (S) ≤ 0.03 Nitrogen (N) ≤ 0.014 These values ensure a balance of mechanical properties and weldability, making the material suitable for demanding applications. 3. Sizes and Range S355J2H pipes come in a variety of sizes and wall thicknesses. Key characteristics include: Outer Diameter (OD): Typically ranges from 21.3 mm to 508 mm or more Wall Thickness: From 2 mm to 50 mm depending on diameter Length: Custom lengths, with standard lengths around 6m to 12m Form: Circular, square, and rectangular hollow sections Standards: Conforms to EN 10210-1/2 specifications 4. Uses and Applications S355J2H pipes are chosen for applications requiring high strength, durability, and resistance to impact and fatigue: Structural engineering (bridges, buildings, stadiums) Mechanical engineering Construction of cranes and heavy machinery Oil and gas industry (non-corrosive environments) Shipbuilding and offshore structures Automotive and rail sectors Their hollow design offers excellent strength-to-weight ratio, ideal for load-bearing applications.
