Abstract
PURPOSE: To obtain the titled inexpensive external parts with superior corrosion resistance and workability by adding Cr, Mo and Cu to Ni as a base in a well- balanced state, adding a specified amount of Fe while maintaining the corrosion resistance, and further adding W.
CONSTITUTION: To Ni as a base are added, by wt., 16W25% Cr, 5W10% Mo, 1W4% Cu, 5W10% Fe, 1W5% W, <0.03% C, <0.5% Si, <0.4% V, <1% Mn and <1% Ti, Nb or Ta, or <2% in total of two or more among Ti, Nb and Ta. Thus, to Ni with superior corrosion resistance are added Cr with superior corrosion resistance under oxidizing conditions and Mo and Cu with superior corrosion resistance under nonoxidizing conditions, and in order to use the elements as a ferroalloy, Fe is added to reduce the cost. C, Si, V, Ti, etc. added by such very small amounts maintain the corrosion resistance after brazing.
