Rolling Method

The cladding steel plate was successfully produced using vacuum cladding rolling method. In cladding steel plate, cladding interface vanished and was replaced new recrystallized grains, and no interface defects or inclusions were detected. Z direction tensile testing indicated that tensile fracture occurred in basal materials, i.e. strength and contraction of cross area are those of basal materials. Furthermore, with decreasing vacuum level of electron beam welding, size and amount of interface inclusions would obviously increase.

Tempering Resistance

The effect of heat treatment on the microstructure and mechanical properties of High Strength steel plate Q960E for construction machinery was investigated. The result shows the quenching temperature have obvious effects on the mechanical properties, DQ can improve the toughness and the enchance tempering resistance, precipitations become more and bigger with the rise of the tempering temperature.
