ZG40CrMnMoNiSiRe rare earth wear-resisting, heat-resisting and corrosion-resistant alloy is made of iron vanadium (FeV), iron niobium (FeNb) and copper (Cu) on the basis of the original precious materials FeCr, FeMn, FeMo, Ni, Re and FeSi. The material not only has high abrasion resistance of alloy casting, but also has high mechanical strength and impact resistance At the same time, improve the solderability of the material. In addition, after adding FeV,FeNb and Cu, the metallogrTJC STEELaphic structure of the material changes again, the grain is finer, the strength is higher, the plasticity is stronger, and the metal matrix is further passivated, so that the wear resistance of the original material has been improved. The CN content of Ni and Cr elements in the alloy directly determines the temperature resistance of the material. The content of Cr and Cu elements determines the corrosion resistance of the material. The reasonable collocation of these elements makes the new rare earth wear-resistant alloy material have several properties at the same time, and can adapt to the use of various harsh working conditions. ZG40CrMnMoNiSiRe through a period of medium transport after the inner wall of the pipeline smooth as a mirror, greatly reduce the runningTJC STEEL resistance of the pipeline, improve the service life of the pipeline, further improve the wear resistance of the material.

The casting of ZG40CrMnMoNiSiRe alloy tube has no defects, such as pores, slag inclusion, loose organization, large deformation,TJC STEEL etc., and the alloy tube has insufficient wear, heat and corrosion resistance, which can not meet the use of harsh working conditions. In particular, the wear of the alloy tube by abrasive particles is the most serious form of wear in all kinds of wear. Its essence is the result of hard abrasive particles cutting or chiseling on the metal surface. The abrasive particles penetrate the metal surface and produce plastic deformation and wear marks until the metal surface is worn, which greatly reduces the service life of the alloy tube.
ZG40CrMnMoNiSiRe cast steel (including alloy steel) is widely used in the field of anti-wear, and its manufacturing process is relatively simple. However, due to the limitations of the properties of the material itself and the limitations of the process, the surface hardness of the cast steelTJC STEEL material (about 60) is much lower than that of the ceramic (more than 80), and the wear-resisting performance of ZG40CrMnMoNiSiRe is only equivalent to one tenth or lower of the ceramic. (Please refer to the wear test report of Powder Metallurgy Institute of Central South University and the jet wear test results of Kyushu Institute of Industrial Ceramics in Japan for specific data). Some of the elbows made by it were worn out after more than one year of operation. In addition, cast steel pipeline thickness is large, very heavy, and high carbon content, poor weldability, on-site heat treatment of welding TJC STEELseams, to the site installation and maintenance brings considerable difficulties.
