Q460E is a steel plate for high strength structural tempering, also known as high strength plate and low alloy high strength plate.
High strength plate is characterised by high strength and high yield value. The grades are: Q390, Q420, Q460, Q500, Q550, Q690, and these grades.
Q460E is composed of 'Q' expressed by the yield; 460 indicates that the yield value of the steel plate is 460MPa; 'E' expresses the steel plate for the impact test for -40 ° (commonly used grades were C, D, E).
Q460E steel plate implementation standard: (GB/T1591 or GB/T3274).
Q460E steel plate conventional product delivery status: tempered (quenched + tempered).
Q460E steel plate can be made thickness direction performance: Z15, Z25, Z35.
Q460E steel plate flaw detection level: 'one probe, two probe, three probe'.
Q460E steel plate density: 7.85/cubic metre.
Q460E mechanical properties: Q460E thickness ≤50 yield strength 460Mpa; tensile strength 550-720; Q460E thickness >50-100 yield strength 440Mpa; tensile strength 550-720; Q460E thickness >100-150 yield strength 400Mpa; tensile strength 500-670; Q460E steel plate elongation at break 17%;
Q460E is widely used in all kinds of engineering machinery, such as mining and all kinds of engineering construction with drilling rigs, electric shovels, electric wheel dump trucks, mining cars, excavators, loaders, bulldozers, all kinds of cranes, coal mine hydraulic support and so on.
