Introduction
EN 10025-2
is a European standard that specifies non-alloy structural steels supplied in
hot-rolled condition. These steels are widely used for general structural and
engineering applications where good strength, weldability, and toughness are
required. EN 10025-2 grades are commonly supplied in the form of plates,
sheets, coils, and strips and are suitable for fabrication, construction, and
mechanical structures.
The standard
defines multiple grades based on minimum yield strength and impact test
requirements at different temperatures. EN 10025-2 structural steels offer an
excellent balance of mechanical strength, formability, and cost-effectiveness,
making them one of the most widely used structural steel standards globally.

Key Features
and Advantages
Excellent
weldability without special preheating in most cases
Good formability and machinability
Consistent mechanical properties
Wide availability and cost-effective
Suitable for large-scale structural fabrication
Compliance with European construction standards
Weldability
and Fabrication
EN 10025-2
structural steels exhibit very good weldability due to controlled carbon
content. Standard welding processes such as SMAW, GMAW, FCAW, and SAW can be
used. For thicker sections and higher grades like S355, controlled heat input
and low-hydrogen consumables are recommended.
The material
is easy to cut, bend, roll, and form using conventional fabrication methods.
Corrosion
Resistance
EN 10025-2
steels provide limited corrosion resistance and are best suited for indoor or
protected environments. For outdoor or aggressive conditions, surface protection
such as painting, galvanizing, or coating is recommended.
Applications
of EN 10025-2 Structural Steel
EN 10025-2
structural steels are extensively used across construction, infrastructure, and
engineering industries due to their excellent strength, weldability, toughness,

Transmission towers and substations
J2 grades
are often used in outdoor installations where low-temperature toughness is
required.
Storage
Tanks and Non-Pressure Vessels
While EN
10025-2 is not intended for pressure vessels, it is commonly used in
non-pressure storage applications.
Applications
include:
Water tanks and reservoirs
Fuel and oil storage tanks (non-pressure)
Silos and hoppers
Material storage containers
S235 and
S275 grades are typically used due to their good formability and weldability.
Marine and
Coastal Structures
EN 10025-2
