S235JRG2 is a structural steel grade produced for general and engineering purposes. It is a carbon steel that is commonly used for structural applications. It has very good tensile strength, with acceptable yield strength at moderate elongation levels. It is also often used for cold forming operations, as it is easy to bend without cracking.
The S235JRG2 steel grade is a structural steel with a minimum yield strength of 235 N/mm2 that can be supplied in plates and other shapes. This grade is widely available in the form of flat and long products and is also sometimes called EN 10025-2. It has a good combination of strength, ductility and weldability. The chemical composition of this grade is strictly specified and allows for small adjustments in both its mechanical properties and chemical composition, thus making it a versatile material for general purpose applications.
This grade is also often used for applications where good weldability is necessary, and is especially suitable for the fabrication of large, heavy-duty components and structures. This steel grade is commonly used in the automotive and construction industries where increased strength and durability are essential. Other applications for this grade include agricultural machinery, shipbuilding, and earth-moving equipment.
S235JRG2 is not a preferable choice for heavy-duty construction but it is often used for fabrication of hollow structural sections, bridges and medium-duty platforms. This grade is also ideal for making components that require wear and corrosion resistance. The mechanical properties of the grade are suitable for low temperature applications where increased strength and notched toughness are required.
This grade has good cold forming properties, allowing it to be tapped, peeled, formed and machined without cracking. It’s also cold formed without any deterioration in its milling properties. Therefore, it’s an ideal structural steel for general purpose use, especially in medium-sized applications that require precise formed parts.
Overall, S235JRG2 is a versatile, reliable and strong structural steel grade suitable for many uses. It’s tolerable tensile strength, strength-to-weight ratio, good weldability and cold forming properties make it the material of choice for many industries and applications.
