UNSPSC 11171603: Stainless steel alloy 316

A type of stainless steel alloy with the following main characteristics: Cr 16,50 to 18,50 percent, Ni 10,00 to 13,00 percent, Mo 02,00 to 02,50 percent, balance equals Fe + minor metallurgical pollutions. This stainless steel enables protection against moisture and heat corrosion.

UNSPSC 11171603 Stainless steel alloy 316 is a Commodity code that does not reflect the work state and local governments are actually buying under this classification. Recent solicitations posted under this code show procurement of coiled aluminum alloy (primarily 3105H21), mobile welding services, and pallet rack wire decking—materials and services unrelated to stainless steel alloy 316. The Colorado Department of Corrections has posted multiple invitations for bid for coiled aluminum in 21-gauge thickness for license plate production at the CCi Tag Plant; the Hillsborough County Board of County Commissioners in Florida issued an invitation for bid for mobile welding and fabrication services at solid waste management facilities; and the Superior Court of California, County of Los Angeles solicited pallet rack wire decking for storage. The mismatch between the code's nominal commodity (stainless steel alloy 316) and the material actually being procured suggests either a cataloging error in how these opportunities were tagged or a deviation in how the state and local procurement bodies are applying the UNSPSC taxonomy to their own acquisitions.

Activity under this code appears limited and geographically scattered across Colorado, Florida, and California. The Colorado Department of Corrections has been the most active buyer, issuing three separate solicitations for coiled aluminum between May and August 2026 in the form of invitations for bid, with response dates ranging from May 20 to August 26, 2026. No clear pattern of repeat buyers or concentrated activity emerges from the available opportunities, and the diversity of commodities tagged under this code suggests it may not be a reliable classification for state and local buyers pursuing materials in this family. Firms tracking this code should verify tagging accuracy with issuing bodies before allocating business development resources.
