Abstract

PURPOSE: To obtain an exterior parts with high corrosion resistance and high strength by forming from a parts base material comprising a Ni alloy containing Cr, Mo, Cu, Ti and Fe added therein in good balance.
CONSTITUTION: The exterior parts is obtained by using an alloy base material comprising, in the wt% 16W25 Cr, 2W5 Mo, 1W4 Cu, 5W25 Fe, 0.3W1.5 Ti, 0.08 or less C and the remainder of Ni and inevitable impurities. Ni in said base material imparts extremely excellent corrosion resistance and Cr enhance strength and corrosion resistance and the lower limit thereof is determined in order to maintain corrosion resistance and, when the upper limit is exceeded, embrittleness is developed. Mo enhance strength and shows excellent corrosion resistance in an environment containing Cl-but, when the upper limit is exceeded, processing property is extremely reduced. Cu also shows same corrosion resistance but, because increasement thereof is not necessarily good from a standpoint of corrosion resistance, a content thereof is limited. Fe dissolves lowering of processing property due to Cr and Mo and makes said parts inexpensive but, when the upper limit thereof is exceeded, corrosion resistance is lost. Ti enhances strength and processing property but, when upper limit thereof is exceeded, embrittleness and low solderability are brought about. C is limited in its amount from the necessity for fixing the same by Ti.
