Product Code:SAE MA3378
Title:Bolts and Screws, UNS N07001, Tensile Strength 1210 MPa, Thread and Fillet Radius Rolled Before Aging, Procurement Specification, Metric
Issuing Committee:E-25 General Standards For Aerospace And Propulsion Systems
Scope: 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 掳C MA3378-1 1210 MPa minimum ultimate tensile strength at room temperature 726 MPa minimum ultimate shear strength at room temperature. Primarily for aerospace propulsion system applications where a good combination of tensile strength and resistance to relaxation at elevated temperature up to approximately 815 掳C is required.【英文标准名称】:Imagingmaterials-Multiplemediaarchives-Storageenvironment
