Types This procurement specification covers bolts and screws made from carbon steels@ high expansion steels@ or corrosion and heat resistant steels of the type identified under the Unified Numbering System as follows: a. UNS K00802 - carbon steel (AMS5061) b. UNS K91505 - high expansion steel (AMS5624) c. UNS K91456 - high expansion steel (AMS5625) d. UNS S32100 - corrosion and heat resistant steel (AMS5645) e. UNS S34700 - corrosion and heat resistant steel (AMS5646) Application Primarily for parts of carbon and low alloy steels@ corrosion and heat resistant steel and alloys@ and high expansion steels not subjected to heat treatment during manufacture. Parts of steels such as AMS5061 are generally for use where stresses are low at moderate temperatures. Parts of corrosion and heat resistant steels and alloys such as AMS5645 or AMS5646 are generally for use at elevated temperatures where stresses are low. Parts of high expansion steels such as AMS5624 or AMS5625 are generally for use at lower temperatures where expansion approaching that of aluminum and magnesium alloys is required. This specification may also be used to control the manufacture@ characteristics@ and quality of parts subjected to heat treatment during manufacture but the stage of manufacture at which heat treatment shall be performed@ the actual heat treatment@ and the mechanical properties of such parts are to be specified@ where required@ on the part drawing. Safety - Hazardous Materials While the materials@ methods@ applications@ and processes described or referenced in this specification may involve the use of hazardous materials@ this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
