S235J0 steel plate detailed mechanical properties

S235J0 is a non-alloyed structural steel material whose mechanical properties are affected by a number of factors, including composition, heat treatment and manufacturing processes. The following are the common mechanical properties of S235J0 steel plate:

1. Tensile Strength: The tensile strength of S235J0 steel plate is usually between 360 and 510 MPa. This indicates how much tension the steel can withstand without breaking.

2. Yield Strength: The yield strength of S235J0 steel plate is usually between 215 and 235 MPa. Yield strength is the threshold at which a material begins to deform.

3. Elongation: The elongation of S235J0 steel plate is usually between 17% and 25%. Elongation indicates the ability of the material to deform during the stretching process, and higher elongation means better plasticity and toughness.

4. Impact Toughness: S235J0 steel plate usually has good impact toughness to resist sudden impact loads. Impact toughness can be assessed by Charpy or V-notch impact tests, with common test temperatures of -20°C or -40°C.

5. Hardness: The Hardness of S235J0 steel plate can be measured by testing methods such as Rockwell Hardness or Brinell Hardness. Hardness values may vary depending on the specific heat treatment process and specification requirements.

Please note that these mechanical properties data are for reference only and actual values may vary according to different manufacturers, product specifications and heat treatment conditions.
