PURPOSE:
The Materials Reliability Division of NIST requires AISI-SAE 4340 steel bars, used to produce precisely machined and heat treated Charpy V-notch specimens. These specimens shall be sold by NIST as standard reference materials to certify the performance of Charpy V-notch impact machines. The steel must be of the highest quality possible to ensure uniform impact properties and long term stability (resistance to aging) of the reference material. The American Society for Testing Materials specification E23 describes this test and these specimens.
