许多工业设施,例如:精炼厂、石化厂、火电厂的重要装备,需用耐硫化物腐蚀的合金做结构材料。但是,高含硫气氛的工作环境,却使金属材料的选用大受限制。为了解决上述问题,Haynes国际有限公司研制了一种新的镍基合金,称为HR-160。 HR-160合金,含钴27％,铬28％、铁4％、硅2.75%、锰0.5％、碳0.05%,其余为镍。由于有相应高的铬与硅,所以镍含量高并不影响抗硫化作用,业已证明,硅是一种抗硫化元素。硅和铬的共同加入,能使合金的表面形成很好的保护层。钴的加入,可提
Many industrial facilities, such as: refineries, petrochemical plants, thermal power plants are important equipment, the use of sulfide-resistant alloys to be structural materials. However, the work environment of high sulfur atmosphere, but the selection of metal materials is greatly limited. In order to solve the above problem, Haynes International Co., Ltd. has developed a new nickel-based alloy, called HR-160. HR-160 alloy containing 27% cobalt, 28% chromium, 4% iron, 2.75% silicon, 0.5% manganese and 0.05% carbon, the rest being nickel. Due to the correspondingly high chromium and silicon, the high nickel content does not affect the anti-sulfur effect and it has been proven that silicon is an anti-sulfur element. The common addition of silicon and chromium, the alloy surface can form a good protective layer. Cobalt can be added
