Standard Specification for Nickel-Molybdenum Alloy Rod
ABSTRACT
This specification covers rod of nickel-molybdenum alloys of UNS N10001, N10665, N10675, N10629, and N10624 for use in general corrosive service. The material shall conform to the required chemical composition for nickel, molybdenum, iron, chromium, carbon, silicon, cobalt, manganese, phosphorus, sulfur, vanadium, nickel, molybdenum, aluminum, columbium, copper, tantalum, titanium, tungsten, zirconium, and magnesium. The alloys shall conform to the required mechanical properties such as tensile strength, yield strength, elongation, and Rockwell hardness.
SCOPE
1.1 This specification2 covers rod of nickel-molybdenum alloys (UNS N10001, N10665, N10675, N10629, and N10624)* as shown in Table 1, for use in general corrosive service.TABLE 1 Chemical Requirements
