Product Details
Considering the high usage temperature of such alloys, it is necessary to have good oxidation resistance and corrosion resistance. The chromium content should be increased to about 20%, and the nickel content should be correspondingly increased to 25% or even 35-40% to stabilize the matrix structure. In order to generate effective solid solution strengthening, a considerable amount of high melting point elements such as tungsten, molybdenum, and niobium are added, with a maximum total amount of 10% to 12%. In some solid solution strengthening iron-based deformation high-temperature alloys developed in China, a small amount of nitrogen is added to achieve a strong solid solution strengthening effect, achieving satisfactory results. In addition, a small amount of aluminum and titanium are added to some alloys to enhance the solid solution strengthening effect, but the addition amount does not exceed 1% to 1.2%. Some sheet alloys require high strength, so in addition to solid solution strengthening, an appropriate amount of aluminum and titanium are added, supplemented by aging strengthening. Add trace amounts of boron, cerium, and zirconium to achieve good grain boundary strengthening effect.
