Welded Circular Fine Grain Welded Steel Tubes for Structural Steelwork

Material Specification

DIN 17123 specifies the requirements for welded circular fine grain steel tubes used in structural steelwork. These tubes are designed to provide high strength and durability, making them suitable for various construction applications. The standard covers several steel grades, including StE255, StE285, StE355, StE420, and StE460, each offering distinct mechanical properties to cater to different structural needs.

Key Features

High Strength: The steel grades specified under DIN 17123 offer excellent tensile strength, making them ideal for load-bearing applications.
Fine Grain Structure: The fine grain structure enhances the toughness and ductility of the steel tubes.
Weldability: These steel tubes are designed for easy welding, facilitating their use in complex structural designs.
Corrosion Resistance: The chemical composition provides a degree of resistance to corrosion, extending the lifespan of the structures.
Versatility: Suitable for various structural applications, including bridges, buildings, and industrial frameworks.

Chemical Composition

The chemical composition of these steel grades is crucial for their performance. Below is a table presenting the typical chemical composition for each grade:

Elongation (%)	≥ 20	≥ 19	≥ 18	≥ 17	≥ 16

Steel Grade

The steel grades covered under DIN 17123 are designed to meet various structural requirements:

StE255: Suitable for general structural applications with moderate strength requirements.
StE285: Offers slightly higher strength, suitable for more demanding structural applications.
StE355: Provides a balance of strength and ductility, ideal for a wide range of structural uses.
StE420: High-strength steel suitable for heavy-duty structural applications.
StE460: Offers the highest strength, ideal for the most demanding structural environments.

Application

These steel tubes are widely used in:

Construction of bridges and buildings
Industrial frameworks and supports
Structural components in machinery
Infrastructure projects requiring high-strength materials

Possible Alternative Grades

Depending on specific requirements, alternative steel grades may be considered:

EN 10219 S355J2H: Offers similar mechanical properties and is often used in structural applications.
ASTM A500 Grade C: A North American standard that provides comparable strength and ductility.
BS 4360 Grade 50D: A British standard with similar applications in structural steelwork.
