WQ960 superalloy steel plate introduction and industrial application
WQ960 steel plate introduction:
WQ960 belongs to the quenched and tempered steel plate for high-strength structure, and the steel plate is delivered in the quenched and tempered (tempering + normalizing) state. The yield strength of WQ690 is above 960MPa, the general thickness is not more than 50mm, and most of the thickness is within 30mm, so it is widely used in the manufacture of more than 100 tons of mine truck floors, pumping machinery, excavators, truck cranes, crawler cranes, coal mine hydraulic supports, etc.
WQ960 implements the WJB (Wugang Technical Agreement) standard, corresponding to GB (national standard) Q960 and EN (European standard) S960Q.

WQ960 quenched and tempered high-strength plate processing performance: steel plate can be cold worked, bent and cut processing. When the gas is cut off, cracks do not occur even if it is not preheated. When preheating, quenched and tempered steel is processed below the tempering temperature. High wear and corrosion resistance: Due to the presence of copper, chromium and other alloying elements, compared with general steel, it has good corrosion resistance, high hardness, and good wear resistance.
