ZG40Cr8MnMoNiSiRe is a type of cast steel that is commonly used in the production of rare earth alloy wear-resistant pipe fittings, including flanges. It is a high-strength material that offers excellent wear resistance and improved mechanical properties compared to traditional carbon steels.

The chemical composition of ZG40Cr8MnMoNiSiRe includes elements such as chromium (Cr), manganese (Mn), molybdenum (Mo), nickel (Ni), silicon (Si), and rare earth elements like cerium (Ce) and dysprosium (Dy). By increasing the chromium content in the rare earth alloy, the wear resistance is greatly enhanced.

ZG40Cr8MnMoNiSiRe flanges are designed to provide improved resistance to corrosion, wear, and mechanical stress in applications where durability and reliability are crucial. These flanges are commonly used in industries such as mining, cement, and power generation, where they are exposed to abrasive materials and harsh environments.

It is worth noting that ZG40Cr8MnMoNiSiRe is a rare earth alloy, which means it contains elements from the rare earth group. The addition of rare earth elements further enhances the material's properties, making it suitable for demanding applications.

Rare earth alloy wear-resistant pipe

Advantages of ZG40CrMnMoNiSiRe:

Horizontal centrifugal casting process of rare earth alloy wearresistant pipe

Horizontal centrifugal casting process of rare earth alloy wearresistant pipe

The wear and tear of rare earth alloy is a phenomenon of material loss caused by relative motion between objects.

Rare earth alloy wear-resistant pipe is produced by horizontal centrifugal casting, in which the smelted liquid metal is passed through the pouring riser and diverted into the rotating mold barrel (the speed of the mold barrel is generally 800-1000 rpm), under the action of centrifugal force A casting method for filling and solidifying into a casting. The horizontal centrifugal casting machine is used for casting various tubular castings and various carbon steel, alloy steel pipes and double-layer steel rolls that require different compositions of inner and outer layers.


Liquid metal can form a hollow cylindrical free surface in a mold without a core. In the production process, the casting process is greatly simplified, with high productivity and low cost. Under the action of centrifugal force, the metal liquid improves the ability of metal to fill the mold, so some alloys and thin-walled castings with poor fluidity can be produced by centrifugal casting.

Due to the centrifugal force, casting defects are improved, shrinkage holes (shrinkage porosity), pores, inclusions and other defects are reduced, and the mechanical properties are improved. Because centrifugal casting has no riser runway, etc., the utilization rate of metal is improved.
