Steel Investment Foundries

NAICS 331512 (Steel Investment Foundries) is a specialized manufacturing category focused on producing high-precision metal components through investment casting techniques. These foundries create intricate metal parts with tight tolerances, typically for aerospace, defense, medical, and industrial applications. The primary products include complex metal castings, coupling halves, levers, mounting components, and other engineered metal parts that require exceptional dimensional accuracy and surface finish.

Federal contract awards in this NAICS category primarily involve the Defense Logistics Agency (DLA) Land and Maritime and DLA Aviation, with contract values ranging from $100 to $138,000. Most awards are firm fixed-price purchase orders for specific quantities of coupling halves, quick disconnects, and precision metal components. Frequently awarded entities include small businesses like Aero-Dyne Supply Co., Norcatec LLC, HC Merchandisers, and Texas Aerospace Services. Approximately 10-15% of awards are designated as total small business set-asides, while the majority are open to all responsible sources. Performance locations are predominantly across the United States, with contractors located in states like California, New York, Georgia, and Illinois.

Recent federal contract opportunities continue the pattern of specialized procurement, primarily through the Defense Logistics Agency. Solicitations typically request small quantities of coupling halves and metal components, with quantities ranging from 6 to 126 units. Delivery times vary from 74 to 297 days after order, and most opportunities are structured as electronic Request for Quotes (RFQs). Approximately half of the recent opportunities are set aside for total small businesses, targeting Steel Investment Foundries under NAICS 331512. Delivery locations predominantly include DLA Distribution centers in San Joaquin and Depot Hill, with a focus on precise metal components for military and logistics applications.
