1. What is EN 10210 S355J2H Square Pipe?

EN 10210 S355J2H Square Pipeis a hot-finished structural hollow section made from non-alloy structural steel, designed to meet the EN 10210-1 standard. The designation "S" indicates structural steel, "355" denotes a minimum yield strength of 355 MPa for thicknesses up to 16 mm, and "J2H" signifies specified impact properties at -20°C, ensuring excellent low-temperature toughness. This makes S355J2H ideal for applications requiring high strength and reliability in cold climates, such as columns, trusses, offshore platforms, and heavy machinery frameworks.

Compared to EN 10210 S355JRH, S355J2H offers superior low-temperature impact resistance (-20°C vs 20°C), making it suitable for harsher environments. Gangsteel’s EN 10210 S355J2H square pipes are engineered for industries seeking robust, high-performance structural solutions. Learn more at EN 10210 S355J2H Square Pipe.

2. EN 10210 S355J2H Chemical Composition

The EN 10210 S355J2H chemical composition, compliant with EN 10210-1, is optimized for strength, weldability, and low-temperature toughness. Below is the ladle analysis for product thickness ≤ 65 mm:

Note: The deoxidation method is designated as FN (rimming steel not permitted). For each 0.001% increase in nitrogen, the phosphorus content is reduced by 0.005%, with a maximum nitrogen content of 0.012% in ladle analysis. The lower carbon and sulfur content compared to S355JRH enhances S355J2H weldability and toughness at low temperatures.
