S355 steel is a European standard structural steel grade, according to EN 10025-2: 2004, material S355 is divided into 4 main quality grades: S355JR (1.0045), S355J0 (1.0553), S355J2 (1.0577) and; S355K2 (1.0596). The properties of structural steel S355 is better than steel S235 and S275 in yield strength and tensile strength.
A yield strength or yield point is the material property defined as the stress at which a material begins to deform plastically. Prior to the yield point the material will deform elastically and will return to its original shape when the applied stress is removed, Yield strength of Q345B is 345 MegaPascals.
The tensile strength of Q345B steel is rated at 470 to 630 MegaPascals (where mega is million) and a yield strength (where the material starts to thin and pull like taffy) at 345 MegaPascals. Like most steels of its grade, it suffers elongation before it pulls apart, typically at 20-21 percent of its initial length.
of the yield point of steel, behind the numbers indicate the yield point value, the unit is MPa yield point such as Q235 (s) of 235 MPa of carbon structural steel. 2) when necessary, can be marked symbols representing steel quality level and deoxygenating methods.
Prior to the yield point the material will deform elastically and will return to its original shape when the applied stress is removed. Yield strength of Q345B is 345 Mega Pascals. Like most steels of its grade, it suffers elongation before it pulls apart, typically at 20-21 percent of its initial length.

Related Product for Q345D/S355J2+N steel plate low alloy structural steel sheet/round bar Steel Structure-AMJ We can design many kinds of steel structures,such Difference of Q345A, Q345B, Q345C Q345D, Q345E in Q is representative of the material yield, 345 refers to the material yield value, minimum to achieve 345 mpa.
Q345 is a steel material. It is a low-alloy steel (C <0.2%), widely used in bridges, vehicles, ships, buildings, pressure vessels. Q represents the yield of this material, behind the 345, the yield refers to the value of this material, approximately 345. And will increase the thickness of the material and its yield value decreases.
the material difference of Q345A, Q345B, Q345C, Q345D and Q345E Q345 is a kind of steel material. It is a low alloy steel (C<0.2%), widely used in bridges, vehicles, ships, buildings, pressure vessels, etc..
