Nickel-Base Alloys—Stainless Foundry Engineering

TABLE 5.19 NICKEL-BASE ALLOYS-STAINLESS FOUNDRY ENGINEERING 

ILLIUM 98 and ILLIUM B perform very well in processes which involve the use of sulfuric, phosphoric, hydrofluoric, nitric, acetic and fluosilicic acids as well as sodium chloride brine, They resist erosion to abrasion in corroding environment. These alloys have high mechanical rigidity. The 98 alloy is nonhardenable while the B alloy is hard-enable.

TABLE 4.7 IRON- AND NICKEL-BASE ALLOYS-STAINLESS FOUNDRY ENGINEERING... 

Nickel (Ni)/Copper (Cu)/Zinc (Zn) Nickel exhibits a mixture of ferrous and nonferrous metal properties, and Ni-based alloys are characterized by corrosion resistance. Therefore, Ni has been widely used in stainless steel (about 65% of the Ni consumed in the Western World) and superalloys/nonferrous alloys (12%). Turbine blades, discs and other critical parts of jet engines and land-based combustion turbines are fabricated from superalloys and Ni-based superalloys. The remaining 23% of consumption is applied in alloy steels, rechargeable batteries, catalysts and other chemicals, coinage, foundry products, and plating (USGS, 2006).
