P2. K-MONEL Heat Review Requirements.pdf

This is a vendor acknowledgement document regarding K-Monel heat review requirements issued by the Defense Logistics Agency for nickel-copper-aluminum (K-Monel) material. The document identifies 80 suspect heat numbers from Special Metals Corporation (formerly INCO Alloys) of Huntington, West Virginia, that may not meet mechanical property requirements of QQ-N-286 due to insufficient aluminum content and inconsistent yield strength. The material specifications require 2.3% minimum aluminum content and yield strength of 90,000 PSI minimum.

The document lists seven approved laboratories authorized to conduct strain rate tests for K-500 raw stock procurement under QQ-N-286 Revision G, including Huntington Alloys, Metallurgical Consultants Inc., Naval Surface Warfare Center, Teledyne Allvac, Mannesmann Rohrenwerke, Westmoreland Mechanical Testing, and ThyssenKrupp VDM USA. Vendors are prohibited from providing raw stock or finished products made from the listed suspect K-Monel heats without contacting the PHNS & IMF contracting officer for adjudication.
