Some steel grades that are equivalent to Q355 steel
The equivalent grades of Q355 steel vary depending on the international standards being used for comparison. Here are some commonly used equivalents:
ASTM A572 Gr 50: This is an equivalent grade to Q355 in the American ASTM standards. It has a minimum yield strength of 345 MPa and is commonly used in structural applications.
S355JR: This is an equivalent grade to Q355 in the European EN standards. It has a minimum yield strength of 355 MPa and is widely used in structural and engineering applications.
SM490B or SM490C: These are equivalent grades to Q355 in the Japanese JIS standards. They have minimum yield strengths of 325 MPa and 365 MPa, respectively, and are commonly used in structural applications.
Grade of Q355 steel (mác thép q355)
Q355 steel is a high-strength structural steel grade that is commonly used in various industries and applications. However, it’s important to note that there isn’t a specific “grade” of Q355 steel as it is not classified using traditional grade designations like Q235 or Q345. Instead, Q355 is typically categorized based on its chemical composition and mechanical properties.
Different variations or types of Q355 steel exist, such as Q355B, Q355C, Q355D, and Q355E, each with its own specific composition and properties. These variations are distinguished by factors like carbon content, additional alloying elements, and specific heat treatment processes.
The Q355B equivalent ASTM material
The equivalent ASTM material for Q355B steel is ASTM A572 Grade 50. ASTM A572 Grade 50 is a structural steel with high strength and low alloy content that is widely utilized in structural applications. Both Q355B and ASTM A572 Grade 50 have a minimum yield strength of 355 MPa (50 ksi) and possess similar mechanical properties.
ASTM A572 Grade 50 offers excellent weldability and formability, making it suitable for a wide range of structural applications, including bridges, buildings, and machinery. It has a higher strength-to-weight ratio compared to many other steel grades, providing superior load-bearing capacity
When comparing equivalencies between steel standards, keep in mind that chemical composition and mechanical qualities may vary slightly. When selecting a comparable ASTM material for Q355B steel, it is recommended that you examine the applicable specifications and standards or seek expert assistance for accurate information.
Q345 vs Q355: What is the difference?
Q345 and Q355 are both high-strength low-alloy (HSLA) structural steels commonly used in various industries and applications. While they share some similarities, there are also key differences between Q345 and Q355. Here is a comparison of the two grades:

Videos 3 and 4 are testing our Illusion Homes insulation and sandwich panels with Acetylene & Oxy-Acetylenes torch.
Acetylene burns at a temperature of 2,200°C or 4,000°F, and when combined with an oxygen tank to produce oxy-acetylene can reach temperatures as high as 3,300°C or 6,000°F, making it the hottest commonly available gas used for cutting steel.
