Реферат

This specification covers the requirements for commercial wrought nonferrous bolts, hex cap screws, and studs manufactured from a number of alloys in common use and are intended for general service applications. The specimens shall be made of materials that conform to the chemical composition requirements for copper, nickel, aluminum, and titanium alloys that are to be determined by chemical analysis. Manufacturing of the specimens shall be by cold or hot forming or machining and stress relieving. Tension, hardness, and shear tests shall be performed to determine the mechanical properties of the specimen which shall be in compliance with the tensile strength, yield strength, elongation, hardness, and shear strength requirements.
