Low-Alloy Steel
S355JR Low-alloy High-strength Steel Plate
EN 10025-2 S355JR grade is a European standard low-alloy high-strength steel plate. Similar with other materials of the same series S355J0, S355J2.With minimum yield of 50,000 KSI, it meets requirements in chemistry and physical properties similar to ASTM A572 / 709.S355JR plates are delivered in hot rolled, controlled rolling, normalizing condition.
EN10025-2 S355J0 steel plate S355 High Strength Structural Steel Plates are high strength, low alloy steel plates falling under the EN 10025: 2004 European standard. It offers minimum yield strength of 50 ksi and a minimum tensile strength of 470-630 Mpa; it is a low carbon structural steel plate with marvellous usability.
High strength low alloy Q355D steel plate are better using than Common carbon structural steel plate Q235B.Q355D steel sheet shall be done Charpy V impacting test at -20 Degree Centigrade when offering.Q355D steel material is equivalent to S355J2 steel material in European specification EN 10025-2.
Q390E high strength low alloy structural steel owned minimum tensile strength at 490 Mpa and minimum yield strength at 390 Mpa for thickness equal or belows 16 millimeters.When rolling steel plate Q390E,the impact test shall be done at minus 40 centigrade.
Power plants Mining and earth-moving equipment
In new chinese steel version GB/T1591-2018 specification,Q355B steel plate,Q355B steel sheet are most common used in the manufacture of construction machinery,ships,bridges,high-rise buildings,structure parts,precise instrument parts and so on.Q355B steel material such as Q355B steel plate,Q355B steel coil,Q355B steel angle bar,Q355B square and rectangular hollow sections are all in warehouse.
Q355 is a kind of low alloy high strength structural steel, widely used in Bridges, Vehicles, Ships,Construction, Pressure Vessels, Special Equipment, etc.
The main mechanical properties are elasticity, plasticity, stiffness, aging sensitivity, strength, hardness, impact toughness, fatigue strength and fracture toughness. Elasticity: Metal material deforms when it is subjected to external force. When the external force is removed, it can restore its original shape.
Q355NH steel plate under China GB/T 4171 standard, it is a kind of weathering steel. Q355NH weathering steel plate is the high tensile strength weathering steel plate, it has 490-630 Mpa tensile strength. More information about Q355NH weathering steel technology, please see the following: Q355NH steel plate comprehensive performance: Q355NH steel plate has good weldability and low temperature impact toughness, suitable for architecture, artifacts such as weather resistance of weldments.
