Q960D high strength steel plate

Q960D is a quenched and tempered high-strength plate produced in accordance with the national standard, and the yield strength is greater than 960MPa grade steel plate.

The implementation standard of Q960D steel plate is GB/T16270-2009 standard. The designation method of Q960D high-strength plate and low-alloy steel plate is the same, and the first letter of “yield” of the steel plate is capitalized, and the minimum yield strength value specified by the steel plate is in MPa, plus The quality grade symbols of the upper steel plate, in order to indicate.

Q960D steel plate smelting method is oxygen converter or electric furnace smelting, and the delivery state is quenched and tempered (quenched and tempered).
