Mechanical Properties of S355JR Steel Equivalent Grades
The mechanical performance of S355JR steel equivalent grades is closely aligned, particularly in yield strength and tensile strength.
| Grade | Yield Strength (MPa) t≤16mm | Tensile Strength (MPa) | Elongation (%) | Charpy Test Temp (°C) | Impact Energy (J) |
|---|---|---|---|---|---|
| Q345B | 345 | 470–630 | ≥20 | 20 | ≥34 |
| A572 Gr 50 | 345 | ≥450 | ≥18 | – | – |
| S355JR | 355 | 470–630 | ≥22 | 20 | ≥27 |
| ST52-3 | 355 | 490–630 | ≥22 | 0 | ≥27 |
| SM490B | 295 | 490–610 | ≥18 | – | – |
These values confirm that S355JR steel equivalent grades can be reliably interchanged in many structural applications.

What is S275J0 material equivalent to?
S275J0 steel plate/sheet is in EN 10025 standard, the material number is 1.0143. The equivalent grades of S275J0 steel are DIN 17100 St 44-3 U, NFA 35-501 E 28-3, UNI 7070 Fe 430 C, BS 4360 43 C, UNE 36.080 AE 275 C, ASTM A 578 Gr. 70.
What is the difference between S275 JR and J0?
S275 J0 steel has a guarantee of resilience at 0°C> 27J, while s275JR steel has, when required, a guarantee of resilience at a temperature greater than 20°C> 27J.
What is the difference between A36 and S275J0?
ASTM A36 has moderate corrosion resistance due to its low carbon content. However, it is not recommended for use in marine environments, as it may need to be corrected quickly. S275JR, on the other hand, has better corrosion resistance due to its higher manganese content.
What material is S275 j0?
S275JO is a readily weldable low carbon manganese steel with good impact resistance. This material is commonly supplied in the untreated or normalized condition. Machinability of this material is similar to that of mild steel.
