Manufacturing Sequence for Fabrication of High-Strength Steel Parts 300M or 4340 Modified Low-Alloy Steels 270,000 psi (1860 MPa) Tensile Strength and Higher
ARP1631
This document establishes the requirements for the sequencing of processes relating to parts fabricated from 300M or 4340 modified steel heat treated to, or to be heat treated to, 270,000 psi (1860 MPa) minimum ultimate tensile strength (UTS) and higher.
Rationale: This standard is being reviewed as a part of the SAE’s five year review policy. The committee will look at possible changes to general guidance and information, testing protocols, and other potential updates throughout the standard.
