S960QL grade is a European standard special alloy structural steel, which belongs to quenched and tempered high yield strength structural steel. S indicates structural steel, 960 is a yield value, in MPa, Q indicates delivery conditions, and L indicates that the impact energy is specified when the temperature is not less than -50℃ The smaller value of. S960QL steel plate is a material in the European standard EN 10025-6.
Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. A514 grade Q quenched and tempered steel, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.
The research methods of isothermal treatment of A514 grade Q quenched and tempered steel, wear-resistant plate include many excellent technologies, such as optical microscope, transmission electron microscope, X-ray diffractometer and electron backscatter diffraction technology. With the increase of annealing temperature, the proportion of ferrite in wear-resistant plate will gradually decrease, and bainite will increase, while the retained austenite will be distributed in ferrite grain boundary and crystal in elliptical and fine strip shape.
10# seamless steel pipe chemical composition : C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. 10# seamless steel pipe mechanical properties: recommended heat treatment temperature: 930℃, tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%, impact energy is not required. A514 grade Q quenched and tempered steel, 10# seamless steel pipe has high plasticity and toughness, no temper brittleness tendency, and good weldability. Its machinability under cold drawing or normalizing treatment is obviously improved. In cold state, 10# seamless steel pipe is easy to be extruded and molded, but its strength is low, and its hardenability is very poor.
