Below are the tables to show the steel grade S355 datasheet including chemical composition, yield strength, tensile strength and elongation, etc. All data sheet of DIN EN 10025-2 is the same as BS EN 10025-2 and other EU member states.
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.
Apr 24, 2017 · 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

May 31, 2014 · yield strength is the primary factor for a mech designer. MUCH more imp. that ultimate. so the greater yeild= stronger for any practical design. IIRC the numeric distance between Ultimate and Yield is roughly proportionate to the percent of elongation during a tensile test (since this is kinda two ways of explaining the same phenomenon). so a , material s420j0 equivalent
