Molybdenum alloy, powder metallurgy process has been used to produce molybdenum products since 1910. Until 1945, powder metallurgy process has been the only industrial production method for manufacturing molybdenum sheet, wire and bar. A nonferrous alloy composed of molybdenum as matrix and other elements. The main alloy elements are titanium, zirconium, hafnium, tungsten and rare earth elements.304 Barra de barra de canal U de acero inoxidable con alta calidad
Molybdenum alloy is a non-ferrous alloy composed of molybdenum as matrix and other elements. The main alloy elements are titanium, zirconium, hafnium, tungsten and rare earth elements. Titanium, zirconium and hafnium not only strengthen the molybdenum alloy by solid solution and maintain the low-temperature plasticity of the alloy, but also form a stable and dispersed carbide phase to improve the strength and recrystallization temperature of the alloy. Molybdenum alloy has good thermal conductivity, conductivity and low coefficient of expansion. It has high strength at high temperature (1100 ~ 1650 ℃ , and is easier to process than tungsten. It can be used as grid and anode of electronic tube, supporting material of electric light source, die casting and extrusion die, parts of spacecraft, etc. Because molybdenum alloy has low temperature brittleness and welding brittleness, and is easy to oxidize at high temperature, its development is limited. Molybdenum alloys produced in industry include molybdenum titanium zirconium series, molybdenum tungsten series and molybdenum rare earth series alloys. The first type is widely used. The main strengthening ways of molybdenum alloys are solution strengthening, precipitation strengthening and work hardening. Molybdenum alloy plate, strip, foil, pipe, bar, wire and profile can be prepared by plastic processing, and its strength and low-temperature plasticity can be improved.Tubo de acero inoxidable soldado de grado 304
An alloy composed of molybdenum and other elements. Among refractory metals, molybdenum and its alloys have good thermal conductivity, conductivity and low expansion coefficient (similar to the glass used for electronic tubes), high strength at high temperature (1100 ~ 1650 ℃, and are easy to process compared with tungsten. Therefore, molybdenum and its alloys are widely used in electronic tubes (grid and anode), electro-optic sources (supporting materials), metal processing tools (die casting and extrusion molds and perforation plugs) It has been applied in the manufacturing sector and the aerospace industry. Molybdenum can resist the etching of molten glass, and its oxide will not pollute the glass. Since 1943, molybdenum has been used as heating electrode in glass industry. Mo-30w alloy has excellent corrosion resistance to molten zinc and has been successfully used in zinc smelting industry. Molybdenum is also used to manufacture heat exchangers and valves in sulfuric acid production.304 no.8 super espejo acabado hoja de acero inoxidable
