Q345 Steel Properties and Introduction Q345 steel is a Chinese GB standard Low Alloy High Strength Structural Steel, material density is 7.85 g/cm3, tensile strength is 470-630 Mpa, and yield strength is 345 MPa.
Dec 31, 2018 · The yield strength or yield point is the property of the material and is defined as the stress at which the material begins to plastic deformation. Before the yield point, the material will be elastic and return to its original shape when the applied stress is removed. The yield strength of Q345B is 345 mpa.
GB/T1591 Q345 includes five different steel grades as Q345A,Q345B,Q345C,Q345D and Q345E.These high tension steel grades owned the same mechincal properties,minimum yield strength at 345Mpa and tensile strength within 470-630Mpa.
Steel grade Q345B is the most common used as high strength low alloy structural steel in industry area.Xinsteel can offer steel coils,steel plates,angles,channels for Q345B materials.The equivalent steel grade with Q345B are EN 10025-2 S355JR,ASTM A572/A572 A572 Grade 50
Q235 steel is equivalent to Japenese steel grade SS400 in application, the only difference is that ss400 steel requires only S,P composition < 0.050, Q235 has requirements for More element C, Si, Mn, S, P. Yield strength of q235 is >235Mpa, which is almost the same to SS400 245Mpa.
Q345 low-alloy steel yield strength is 345MPa,Q345 steel has include five grades:Q345A, Q345B, Q345C, Q345D, Q345E steel,and Q345 low-alloy structural steel plate widely used in bridges, vehicles, ships, buildings, pressure vessels, special equipment, etc
Tensile strength of Q345 steel with random pitting corrosion based on numerical analysis Pitting corrosion is inevitable for steel structures during their service phase. The severity of corrosion is greatly affected by the surrounding environment, and corrosion itself reduces the effective thickness of steel plates.
low alloy steel plate grade 50 q345 grade steel. low alloy steel plate grade 50 q345 grade steel Speedy Metals Information for ASTM A572 Grade 50 Plate Grade 50 is a high strength, low alloy steel that finds its best application wherethere is need for more strength per unit of weight. Q345R Pressure Vessel Steel Plate for Boiler Manufacture
Sep 28, 2010 · The tensile strength is 375-500 MPa. The min. yield point of Q345 is 345 MPa for thicknesses < 17mm, 325 MPa for 16-35mm, 295 MPa for 35-50mm, and 275 MPa for 50-100mm. Tensile strength 470-630 MPa.
