Aug 27, 2020 · Q355 steel is a Chinese low alloy high strength structural steel, which replaced Q345, the material density is 7.85 g/cm3. According to GB/T 1591 -2018, Q355 has 3 quality levels:Q355B, Q355C and Q355D. Q is the first letter of Chinese Pinyin:qu fu dian, which means Yield Strength, 355 is the minimum value of yield strength 355 MPa for steel thickness 16mm, and tensile strength What is GB T1591 Q345B steel equivalent ASTM - Bebon SteelYield strength ReH/(N/mm2) Tensile strength Rm/(N/mm2) Elongation A/% Charpy V test (t16mm) min (3mmt16mm) (3mmt40mm) min:Temperature/ Impact energy (Longitudinal)/J min:Q345B:345:470-630:20:20:34:A572 Gr 50:345:450:18-- q345b steel equivalent indian standard yield strengthMechanical Properties of Chinese Low Alloy Steel Q345B. 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.Like most steels of its grade,it suffers elongation before it pulls apart,typically at 20-21 percent of its initial length.2,Tensile strength.
