What kind of steel is 05CuPCrNi steel plate for construction machinery?

The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the 05CuPCrNi steel plate for construction machinery production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.

High strength wear-resistant plate is a kind of plate product used for large area wear condition. It is made by overlaying a certain thickness of high hardness and excellent wear-resistant layer on the surface of ordinary low carbon steel or low alloy steel with good toughness and plasticity. After production, the high-strength wear-resistant plate will be tested for its strength and bearing pressure. High strength wear-resistant plate is very wear-resistant, in the case of no accident, the service life of 05CuPCrNi steel plate for construction machinery, high-strength wear-resistant plate is very long.

As a new type of coil material, compared with the traditional steel coil, 05CuPCrNi steel plate for construction machinery, the alloy steel coil and sheet has a great improvement in performance properties. The alloy steel coil and sheet has good thermal strength and oxidation resistance at high temperature. Moreover, the corrosion resistance of alloy steel coil and sheet is better. After long-term corrosion, the service life of traditional coil plate will decrease rapidly, but the new type coil, the alloy steel coil and sheet has strong corrosion resistance, and its service life is far longer than that of traditional coil plate.

Boiler steel plate mainly refers to the hot-rolled medium and thick plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The commonly used 05CuPCrNi steel plate for construction machinery, boiler steel is low carbon killed steel smelted in open furnace or low carbon steel smelted in electric furnace, with carbon content in the range of 0.16% - 0.26%.

05CuPCrNi steel plate for construction machinery, 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.
