Hybox® 355

Product catalog summary

Introduction
Hybox® 355 is a high-grade, cold-formed structural hollow section known for its excellent formability and toughness. It is batch-tested for quality assurance and compliance with design codes. Key features include a minimum strength of 355 MPa, suitability for low-temperature applications, excellent weldability, and CE marking for compliance with the Construction Products Directive.

Technical Data
Hybox® 355 hollow sections are designed for construction and mechanical applications, adhering to the European Standard EN10219: S355J2H. They offer a minimum yield strength of 355 N/mm² and come with an inspection certificate type 3.1 to EN10204. The sections are specified by product name, dimensions, and thickness in millimeters.

Chemical Composition and Mechanical Properties
The material features a yield strength of 355 N/mm² and tensile strength between 510-680 N/mm², with an elongation of 20% and an impact strength of 27 J at -20°C. The chemical composition includes a maximum of 0.22% Carbon, 0.55% Silicon, 1.60% Manganese, and 0.030% for both Phosphorus and Sulfur.

Dimensional Tolerances
For circular sections, the outside dimension tolerance is ±1% with specific thickness tolerances based on diameter. Square and rectangular sections have side length tolerances varying with size, and all sections have specific straightness and mass tolerances.

Size Range Charts
Detailed size range charts are provided for circular, square, and rectangular hollow sections, indicating available thicknesses for various diameters and side lengths.

Sectional Properties
Detailed sectional properties are provided for Hybox® 355 circular, square, and rectangular sections, including dimensions, thicknesses, and tolerances.
