Type: This specification covers metric bolts and screws made from a corrosion and heat resistant nickel-base alloy of the type identified under the Unified Numbering System as UNS NO7001. The following specification designations and their properties are covered: MA3378 1210 MPa minimum ultimate tensile strength at room temperature 520 MPa stress-rupture strength at 730 ??MA3378-1 1210 MPa minimum ultimate tensile strength at room temperature 726 MPa minimum ultimate shear strength at room temperature Application: Primarily for aerospace propulsion system applications where a good combination of tensile strength and resistance to relaxation at elevated temperature up to approximately 815 ??is required. 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.
