SAE MA 3374A-1995 (SAE MA3374A-1995)

Bolts and Screws, UNS S66286, Corrosion and Heat Resistant Steel, Procurement Specification, Metric ( Reaffirmed: May 1995 Oct 2001 May 2006 )

This document covers metric bolts and screws made from a corrosion and heat resistant, age hardenable iron base alloy of the type identified under the Unified Numbering System as UNS S66286. The following specification designations and their properties are covered: MA3374 900 MPa minimum ultimate tensile strength at room temperature 480 MPa stress-rupture strength at 650 degrees C and MA3374-1 900 MPa minimum ultimate tensile strength at room temperature 590 MPa minimum ultimate shear strength at room temperature. Primarily for aerospace propulsion system applications where a combination of fatigue strength, tensile strength, stress-rupture strength and resistance to relaxation at elevated temperatures is required.
