The properties of S235JR steel, a non-alloy structural steel grade specified in the European standard EN 10025-2, include:
Yield Strength: The minimum yield strength of S235JR is 235 MPa (megapascals), which means it can withstand a load of 235 N/mm² before deformation occurs.
Tensile Strength: The tensile strength of S235JR ranges from 360 to 510 MPa, indicating its ability to resist tension or pulling forces.
Elongation: S235JR typically has an elongation percentage of 26% to 20mm, which describes its ability to deform before breaking under tensile stress.
Impact Energy: S235JR undergoes a Charpy V-notch impact test at room temperature and has a minimum impact energy of 27 Joules, indicating its toughness and resistance to brittle fracture.
Hardness: S235JR steel is not typically specified with a hardness value, as it is primarily focused on its mechanical properties rather than hardness.
Weldability: S235JR exhibits good weldability, allowing for ease of fabrication and joining through various welding methods.
It's important to note that these properties are typical values and may vary depending on the specific thickness, shape, and heat treatment of the material.
