EN 10111 Chemical composition of S355 steel

S355 steel is a grade of steel manufactured according to the European standard EN 10111, which is a low-alloy structural steel. This kind of steel has excellent mechanical properties and is widely used in many engineering fields.

EN 10111 S355 Steel Features:

High strength: S355 steel has a high tensile strength and yield strength, enabling it to withstand large loads and bending stresses.

Good weldability: The steel is suitable for conventional welding, bolting and riveting and other processes, with good weldability.

Good impact toughness: under low temperature conditions, S355 steel can still maintain good impact toughness, suitable for cold environment applications.

Weather resistance: S355 steel has good weather resistance, can resist atmospheric corrosion and the influence of the external environment, and extend the service life of the material.

EN 10111 S355 Tempering Chemical Components:

Carbon (C) : ≤ 0.24%

Phosphorus (P), sulfur (S) : ≤ 0.04% (total amount of both)

Other alloying elements such as manganese (Mn) and silicon (Si) are also within a certain range.

EN 10111 Mechanical properties of S355 steel:

Tensile strength: Depending on the specific standard and the heat treatment method, the tensile strength of S355 steel is usually between 440 and 570MPa.

Yield strength: not less than 355MPa.

Elongation: also meets the relevant standards and requirements.

S355 steel has a very wide range of applications, including but not limited to the following areas:

Construction: In building structures, S355 steel is often used for load-bearing components, such as beams, columns and beam-column connectors.

Bridges: This steel can be used to make components such as main beams, pillars and bridge panels in bridge structures.

Machinery: In mechanical engineering, S355 steel is widely used in the manufacture of various parts and structures, such as automotive parts, machine tool structures and mechanical connectors.

Marine engineering: Because of its good corrosion resistance and resistance to seawater erosion, S355 steel is suitable for offshore platforms, Marine structures and ship construction.
