EN 10210-1 is a European standard that specifies the technical delivery conditions for hot finished structural hollow sections of non-alloy and fine grain steels. It features simple form, excellent strength properties, durable, compact structure and wide specifications and dimensions. Adopting appropriate types of steels can optimize function and affordability of this hollow section pipe. These sections are typically used in construction and mechanical applications where high strength and durability are required.
Key Points of EN 10210-1
1. Product Types:
Hollow Sections: These can be square, rectangular, or circular hollow sections.
Seamless and Welded: The standard covers both seamless and welded hollow sections.
2. Material Grades:
The standard specifies different steel grades, with various mechanical properties like yield strength, tensile strength, and elongation.
Common steel grades include S235, S275, S355, etc., where the number represents the minimum yield strength in MPa.
3. Dimensions and Tolerances:
The standard defines specific dimensions for hollow sections, including outer dimensions, wall thickness, and cross-sectional properties.
Tolerances on dimensions and shape are also specified to ensure uniformity and compatibility in construction.
4. Mechanical Properties:
The standard specifies the mechanical properties that the steel must meet, such as yield strength, tensile strength, and impact resistance at different temperatures.
5. Chemical Composition:
It includes limits on the chemical composition of the steel, ensuring that it has the required characteristics for strength, weldability, and toughness.
6. Testing Requirements:
The standard outlines the testing procedures for verifying mechanical properties, including tensile tests, impact tests, and other quality checks.
Non-destructive testing (NDT) may be required to check for internal defects.
Application
EN 10210-1 hollow sections are widely used in structural applications like building frames, bridges, and in the construction of machinery where high strength and durability are essential. The choice between seamless and welded sections depends on the specific application, with seamless pipes generally offering better strength and pressure resistance.
This standard ensures that the structural hollow sections used in construction projects meet consistent quality and performance criteria across Europe.
