P355NL1 steel plate is alloy special steel, steel for pressure equipment, with good plasticity, toughness, cold bending performance and welding performance. The steel is used to manufacture spherical storage tanks of more than 50 cubic meters, and can also be used to manufacture single-layer coil welding vessels, multi-layer hot-sleeve coil welding vessels, second and third category vessels and low-temperature pressure vessels.
The mechanical properties of 30CrMo steel are as follows: tensile strength 930 MPa, yield strength 785 MPa, elongation after fracture 12%, impact absorption energy 63 J. A572 Gr 50 CS steel carbon plate, 30CrMo steel has high strength and toughness. When the temperature is lower than 500℃, 30CrMo steel has good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance. 30CrMo steel is generally used in quenched and tempered condition.
Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the A572 Gr 50 CS steel carbon plate steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of A572 Gr 50 CS steel carbon plate seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
The high strength A572 Gr 50 CS steel carbon plate low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of A572 Gr 50 CS steel carbon plate ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
