Bolts and Screws, Nickel Alloy UNS N07718, Tensile Strength 1275 MPa Procurement Specification, Metric MA3377A

This document covers metric bolts and screws made from a corrosion and heat resistant, age hardenable nickel base alloy of the type identified under the Unified Numbering System as UNS N07718. The following specification designations and their properties are covered: MA3377 1275 MPa minimum ultimate tensile strength at room temperature 1000 MPa minimum ultimate tensile strength at 650 degrees C 690 MPa stress-rupture strength at 650°C 720 MPa tension to 72 MPa tension fatigue at room temperature and MA3377-1 1275 MPa minimum ultimate tensile strength at room temperature 765 MPa minimum ultimate shear strength at room temperature 720 MPa tension to 72 MPa tension fatigue at room temperature. Primarily for use in aerospace propulsion systems as follows: a. for use up to approximately 650 °C where elevated temperature tensile strength, stress-rupture strength, and resistance to relaxation are required; and b. for use up to approximately 425 °C where fatigue resistance, tensile strength, and shear strength are required.
