Rare earth alloy wear-resistant pipes are mainly used for steel pipes for mechanical structures and carbon pressing equipment, requiring high dimensional accuracy and good surface brightness. It represents the material of 45 steel and so on. GB/T cold drawn seamless steel pipe special-shaped steel pipe). It is mainly used to manufacture various structural parts and parts, and its materials are carbon structural steel and low rare earth alloy structural steel.
Rare earth alloy wear-resistant pipe characteristics
GB/T fine inner diameter seamless steel pipe for hydraulic and pneumatic cylinders). Mainly used in the manufacture of cold drawn or cold rolled seamless steel pipes with fine inner diameters for hydraulic and pneumatic cylinders. Its representative material is 45 steel and so on. GB (stainless steel seamless steel pipes for boilers and heat exchangers).
Mainly used for boilers, superheaters, heat exchangers, condensers, catalytic tubes, etc. in chemical enterprises. High temperature, high pressure and corrosion resistant steel pipes. Its representative materials are 0Cr18Ni1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti and so on. GB/T (stainless steel seamless steel pipe for construction).
Mainly used for ordinary structures (hotels, restaurant decoration) and mechanical structures of chemical enterprises with resistance to atmospheric, acid corrosion and a certain strength of steel pipes. Its representative materials are 0-3Cr0Cr18Ni1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti and so on. GB/T (stainless steel seamless steel pipe for fluid transport).
Mainly used in metallurgy, petrochemical, glass ceramics, fluorescence and electronic materials and other industries. Consumption distribution ratio over the years (excluding China). Rare earth metals and their alloys play the role of deoxidation and desulfurization in steelmaking, which can reduce the content of both to less than 0.001%, form and refine grains, thereby improving the processing properties of steel, improving strength, toughness, corrosion resistance and resistance. Oxidation, etc. Rare earth metals and their alloys are used in the manufacture of ductile iron, high-strength gray iron and vermicular graphite iron. It can change the form of graphite in cast iron, improve the casting process, and improve the mechanical properties of cast iron (alloy steel, cast iron). Adding small amounts of rare earth metals in bronze and brass smelting can improve the strength, elongation, heat resistance and electrical conductivity of the alloy. Adding 1 to 1.5% of rare earth metals to cast aluminum-silicon alloys can improve high-temperature strength. Adding rare earth metals to aluminum alloy wires can improve tensile strength and corrosion resistance. 0.3% rare earth metal is added to Fe-Cr-Al electrothermal alloy.
