Statement of Work for 4340 and 9310 Steel for Charpy Machine Verification Program The National Institute of Standards and Technology (NIST), Material Measurement Laboratory, Applied Chemicals & Materials Division (ACMD), requires American Iron and Steel Institute-Society of Automotive Engineers (AISI-SAE) 4340 and (AISI) 9310 steel bars. They will be used to produce high quality Standard Reference Materials SRMs that are precisely machined, and heat treated for use as American Society for Testing and Materials (ASTM) Charpy V-notch reference specimens [ASTM E23, “Standard Test Methods for Notched Bar Impact Testing of Metallic Materials”]. Charpy V-notch specimens are sold by NIST as standard reference materials to certify the performance of Charpy 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 ASTM E23 standard describes this test and these specimens.
The contractor shall deliver a supply of 4340 and 9310 steel that meets all the technical specifications and can be used to successfully produce high quality NIST SRM specimens for verifying Charpy machines according to ASTM E23.
The steel shall be delivered to: NIST Div 647, Attn: Raymond Santoyo, 325 Broadway, MS 647, Boulder, CO 80305.
The bars shall be packaged in bundles identified with reference to the ingot/billet position from which it was processed, and shipped in lengths of no more than 6 ft. The individual boxes/packages that are shipped shall weigh less than 2000 lb. each (fork lift capacity).
Delivery should be one-year ARO.
The Contractor shall provide documentation stating how the steel was processed, how the steel was formed, results on chemistry grain size, and relevant mechanical properties.
Inspection and Acceptance: Government acceptance expected to take longer than 7 days.
See attached documents for detailed specifications.
