What are the key differences between S235JR and S235J0?

The chemical composition of s235jr and s235j0 is very similar. However, there are some important differences between the two. Let’s look at some of them.

S235JR and S235J0 Chemical composition

S235JR is an extremely important structural steel grade. It has a chemical composition of 0.17 to 0.20 wt.% carbon. It is produced in accordance with the standards of EN 10025-2. In addition to the usual properties of mild steel, it also has higher levels of phosphorous and sulfur.

This material is suitable for applications where the impact energy of the material is less than 27 Joules. Moreover, it is readily bendable and has a good machinability. Therefore, it is often used in vehicle structures.

The most common application of this material is in freight cars and other civil engineering solutions. It is also available in various thicknesses. However, the price may vary from manufacturer to manufacturer. If you’re looking to buy, be sure to ask for the exact metal used.

S235JR and S235J0 Yield strength

Yield strength is a measure of the materials ability to endure a particular structural load. The value is expressed in megapascals (MPa) and can range from 350 to 500 MPa for thin plates. This is an important characteristic of structural steels. It means that the material is able to withstand loads that might otherwise break it.

Structural steels are widely used in various industries. They are suitable for different purposes, including forging, construction, mining, manufacturing, and transportation. Their prices are also competitive. However, their performance depends on the materials’ dimensional capabilities.

Steel grade S235JR is a common choice in the industry. Aside from being a good tensile strength, it is also very easily bendable. In addition, its mechanical properties make it a good choice for welding, especially for non-critical structures. Moreover, it is also a low carbon and is readily available.

S235JR and S235J0 Tensile strength

There are two common structural steels, S235JR and S235J2. They have different chemical compositions, but have many similar properties. These structural steels are used in a wide range of applications.

The tensile strength of S235JR is between 360 and 510 MPa, depending on the thickness. This grade is commonly used in the construction industry. It is also a popular material for vehicle structures.

Grade S235J0 offers excellent toughness and weldability. It is available in a variety of thicknesses and is suitable for low-stressed parts in mechanical engineering. Compared to other carbon steels, it is a lower carbon content and contains a higher level of phosphorous.

In terms of the physical properties, S235J0 has a maximum impact energy of 27 Joules at 0 degrees C. Typical grades are available in a wide range of thicknesses, including 1.0 mm to 400.0 mm.

S235JR and S235J0 mechanical properties

S235JR and S235J0 are steels that have excellent mechanical properties. They have high yield strength, tensile strength and elongation properties. These steels are used for making structures, vehicle structures and shipbuilding.

A number of test methods are used to verify the quality of S235JR and S235J0 steel. During Charpy impact tests, the yield strength of the material is determined. This indicates the maximum load that it can bear without breaking. The stress at which the tensile strength of the metal falls below its yield strength will result in elastic deformation.

In addition to the tensile and yield strengths, the Charpy impact value of the material also shows the minimum temperature at which the material can take a 27 Joule impact. At room temperature, the value is 20 degrees C.

S235JR and S235J0 have a low carbon content and are readily welded. They are available in various thicknesses. Their tensile strength ranges from 360 to 510 MPa.

S235JR and S235J0 Common uses

Structural steel is an important material for construction. It is mainly used in various industries like engineering and transportation. Various grades of steel have their own qualities and applications. The most popular types are S235 and S355.

S235JR and S235J2 are mild steels. They are both under the technical standard EN 10025-2. These are low carbon structural steels that are commonly used in vehicles, cranes and transmission towers.

In terms of mechanical properties, the S235JR non-alloy steel is bendable and has good cold bending properties. At room temperature, the minimum impact energy is 27 Joules. This makes it ideal for welding. Moreover, it has similar machinability to mild steel.

In addition, it is a common material for welded structures and fabricated parts. This grade is generally supplied in the untreated condition. However, manufacturers offer a variety of pricing options.
