In the cement plant, wear-resistant steel plate can be used in the pulverizer blade, chute lining, guide blade, recycling bucket lining, etc., but the cement plant has higher requirements for wear-resistant steel plate, so it needs to select a better function and thicker steel plate. Construction machinery needs to withstand strong pressure and wear. Therefore, the P265GH en 10028-2, wear-resistant steel plates used in construction machinery are steel plates with good performance. These wear-resistant steel plates are mainly used for the whole mechanical equipment or the primary parts of the equipment, such as pieces, bottom plates, drill pipes or the whole bulldozer.

p265gh en 10028-2, Q690 steel is low alloy high strength steel. It belongs to the Chinese GB standard steel. Q690 steel is named after its yield strength value. Q is the abbreviation of yield strength, that is, the yield strength of Q690 steel is 690 MPa. Chemical composition of Q690 steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 1.00, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. The mechanical properties of Q690 steel are: yield strength ≥ 690 MPa, tensile strength 730-940 MPa, elongation after fracture ≥ 14%, impact energy 31J.
