Alloy pipe

The late eighty`s, American technology of rare eath wear resistant steel was introduced into our country. The relevant experts researched and made many experiments. The rare-earth wear-resistant steel had occupied the main position.Rare-earth wear-resistant steel is based on 40 steel. Cr, Ni, Si, Mo, Mn, Re elements are mixed in 40 steel forming low alloy steel which carbon content is 0.35~ 0.45%. Experienced long-term production making and many failures, we summed up a reasonable science and new experience.A certain amount of rare earth element is added into steel can improve the quality of alloy steel and can fining grains also can form a protective film on surface. A certain amount of Mo is added, the alloy under certain temperature and certain antioxidant effect, increase the service life.A certain amount of boron carbide is added, hardness can be controlled in the range HRC45 ~ 65. At the same time solve the contradictions between the hardness and weldability of wear resistant ste...

Rare Earth Alloy Wear-resisting Casting Pipe Rare earth alloy wear-resistant casting tube Uses: Rare high-strength low-alloy heat-resistant, wear-resistant steel parts for the power plant boiler systems in coal, powder, ash slagging pipeline. Features: My company and major universities jointly developed a new type of high-strength wear-resistant alloy of rare earth products, it is crucial to overcome the technical material of cold, heat, cracking, brittleness, deformation, etc., with high strength, good toughness, corrosion resistance, weldability well, the process is using the most advanced centrifugal casting, long life, under the same conditions than the high manganese steel materials, wear the unit around one-third of the high manganese steel, high manganese steel service life is three times above. Bends and branches seamless steel pipe sections with supporting the use, installation and maintenance more convenient. Performance indicators:   Grade: ZG40CrNiMoMnSiRe Hardness: HRC...
