S235 steel concept

S235 steel is a common carbon structural steel manufactured according to the European standard EN 10025. This steel is widely used in Europe and has a variety of grades, such as S235JR, S235J0 and S235J2.

Chemical composition of S235 steel

The chemical composition of S235 steel mainly includes:

Carbon (C) : ≤0.17%

Silicon (Si) : ≤0.35%

Manganese (Mn) : ≤0.65%

Phosphorus (P) : ≤0.030%

Sulfur (S) : ≤0.030%

The ratio and content of these elements ensure that S235 steel has stable physical and chemical properties.

S235 steel features

Good machinability: S235 steel has good plasticity, toughness and weldability, which makes it easy to process and form.

High mechanical properties: the yield strength of S235 steel is not less than 235MPa, and the tensile strength is between 360 and 510MPa, which has high mechanical properties.

Wide range of applications: Because of its good performance and low cost, S235 steel has been widely used in construction, Bridges, machinery manufacturing, shipbuilding, rail transit and petrochemical industry and other fields.

S235 steel has a very wide range of applications, including:

Construction field: Used for the construction of various industrial and commercial buildings, such as factory buildings, frames, steel structures, etc.

Bridge field: Used to build road Bridges, railway Bridges and urban rail transit Bridges.

Machinery manufacturing field: widely used in machine tool, body, wheel hub, doors and Windows and other manufacturing fields.

In general, S235 steel is a kind of ordinary carbon structural steel with stable performance, moderate cost and wide application.
