The S355j2g3 specification is a standard for the aerospace industry, which has been developed by the American Society of Mechanical Engineers. It is one of the most widely used specifications in the world and has become a benchmark for other industries.
The s355j2g3 steel equivalent is a specification that was created by the American Iron and Steel Institute. The specification was created to determine how much carbon content should be in a steel alloy.

The S355j2g3 specification is the definitive guide to understanding and using this popular structural steel. In this blog, we’ll explore the meaning of the specification, as well as provide a downloadable PDF of the standard. We’ll also discuss the mechanical properties of this steel, and how it compares to other types of structural steel. Finally, we’ll provide a list of some common bar equivalents for this grade.
S355J2G3 is a non-alloy structural steel according to EN10025:1990. This standard has now been replaced by EN10025-2:2004 and steels with the S355J2G3 designation are now known as S355J2. We will detail the differences between S355J2 and S355J2G3 in this article.
What is S355J2G3?
S355J2G3 is a high Tensile Low carbon manganese steel which is widely used in various industries such as construction, offshore, shipbuilding, bridges, pressure vessels, and so on. It has excellent weldability and forming properties.
The standard S355J2G3 was first introduced in the year 2000. It supersedes the previous standards of S355J2G1 and S355J2G2. The new standard is EN 10025:2004. This grade of steel is produced in four grades- S355J0C (thickness up to 12mm), S355JR (thickness 12-20mm), S355JO (thickness 20-35mm) and
S355K2C(thickness 35-50mm). All these grades have different chemical compositions and mechanical properties.
The main difference between all these grades lies in their strength values. For example, the yield strength of grade S 355 J0 C is about 355 MPa whereas that of grade S 355 K 2 C is about 510 MPa. The tensile strength also differs greatly for all these grades; the lowest being 365 MPa for J0 C and the highest being 630 MPa for K 2 C.
S355J2G3 is a European standard steel whose code is S355J2G3. This Standard defines the chemical composition of S355J2G3 steels as well as their mechanical properties. This Standard applies to hot rolled flat products (plate, sheet, and strip) in thicknesses up to 250 mm for general applications.

The S355J2G3 standard PDF is a document that provides guidance on the use of the steel grade S355J2G3. It includes information on the chemical composition, mechanical properties, and dimensional tolerances of the material.
S355J2G3 Mechanical Properties PDF
A mechanical property is any characteristic of a material that can be measured or observed, without changing the identity of the material. These properties are usually classified into two categories: physical and chemical.
S355J2G3 is a high-strength low-alloy structural steel that belongs to the group of non-alloyed steels. This steel possesses both good weldability and cold forming properties, making it an ideal choice for various applications.
The following table lists the main mechanical properties of S355J2G3:
Yield Strength: Tensile Strength: Elongation% Hardness (HBW): Reduction of Area%: Charpy V-notch impact test
355 min. 490 – 630 min. 22 30 J at 20ufffdC
S355J2G3 has a minimum yield strength of 355 MPa and a tensile strength range from 490 to 630 MPa depending on thickness. It also exhibits excellent weldability and good cold forming properties, making it an ideal choice for many different applications.
S355J2G3 is a high tensile and low carbon structural steel with a hardness of 50-60 HRC. It is widely used in the construction industry, especially for bridges and buildings.
S355J2 Round Bar Equivalent
S355J2 is a low carbon, high tensile strength structural steel which can be readily welded to other weldable steel. With its low carbon equivalent, it possesses good cold-forming properties. The plate is produced by fully killed steel process and supplied in normalized or controlled rolling condition. S355J2 Application Structural application in freight cars, transmission towers, dump trucks, cranes, trailers, bull dozers, excavators, forestry machines, railway wagons, dolphins, penstocks pipes for dams.
The S355J2G3 steel grade is a high-strength low-alloy structural steel with improved atmospheric corrosion resistance. This means that it is suitable for use in environments where corrosive elements are present, such as in coastal areas. It also has good weldability and machinability properties, making it easy to work with. The standard version of this steel grade includes a minimum yield strength of 345 MPa, which makes it suitable for applications where high levels of strength are required.
Frequently Asked Questions
What material is S355J2G3?
A high-tensile, fine-grained steel for welding dynamic load structures is S355J2G3. The steel can withstand temperatures as low as –20 °C. It is possible to save a significant amount of material compared to S235J2G3 since the yield point is 120 MPa greater.
What does S355J2G3 meaning?
En10025:1990 defines S355J2G3 as a non-alloy structural steel. Since EN10025-2:2004 has taken its place, steels with the S355J2G3 designation are now referred to as S355J2. We have a lot of structural steel plates in stock in S355J2+N.
What is the difference between S275 and S355?
Although S275 offers less strength (than S355), it is well machinable and may be welded. S275 steel gets its name from the fact that its minimum yield on average is 275 N/mm2. In the most demanding situations, such the offshore sector, S355 is often employed.
What is S355J2 AR?
A micro alloyed structural steel called S355J2 is ideal for uses like those in mechanical engineering. The steel has high weldability, with a maximum CEV for all variations of 0.47. For excellent galvanizing qualities, the steel may be provided with a regulated silicon concentration.
What is ASTM A29?
The standard specification for Hot-Wrought Steel Bars, Carbon and Alloy, General Requirements is ASTM A29. Under this standard, carbon and alloy steel bars may be either hot rolled or cold finished. Likewise, hot rolled or cold finished alloy steel bars are also covered.
What does the S stand for in S275?
In the instance of S275 and S355, the letters “S” stand for “structural steel,” while the numbers 275 and 355 indicate various strengths.
What is S355 steel equivalent?
comparable to steel grades ASTM A572 and A709.
What is the difference between S355J2 and s355k2?
S355 K2 +N and J2 + N. The difference between them is that the plates must be tested at -20 and -40, respectively, according to the standard (EN10025). We test the J2 plates at -40 degrees (the same as the tougher K2 standard).
