UNSPSC 23281600: Heat treating machines

Heat treatment includes the controlled heating and cooling of materials at various rates. These treatments induce phase transformations that greatly influence mechanical properties, such as strength, hardness, ductility, toughness, and wear resistance.

UNSPSC 23281600 Heat treating machines (Class) encompasses the purchase of computer numerical control (CNC) machining systems, wire electrical discharge machining (EDM) equipment, shearing machines, and related precision metalworking machinery by state higher education institutions, state transportation departments, county facilities, municipal utilities, and vocational technical colleges. State and local procurement under this code emphasizes capital equipment acquisition—machines for educational programs, production shop operations, and materials processing—rather than consumable heat-treating supplies or services. The issuing bodies are primarily large state university systems and state agencies; Texas A&M University System alone has posted three separate ITBs for CNC and machine shop equipment within the past month, signaling sustained institutional investment in precision manufacturing capability.

Recent activity concentrates in Texas and California, with secondary postings from Florida, Utah, and Missouri. Texas A&M University System is soliciting CNC lathes, machining centers, and general machine shop and welding equipment under ITBs TAMUS-ITB-26-0542 (due July 23, 2026), TAMUS-ITB-26-0541 (due July 15, 2026), and TAMUS-ITB-26-0540 (due July 13, 2026), all via the AggieBid platform. Texas State Technical College issued RFP-315 for Wire EDM machines with a one-year base term and four optional renewals, anticipated value exceeding $100,000, proposals due March 11, 2026. The Texas Department of Transportation (TxDOT) has posted multiple ITBs for OEM replacement parts for Cincinnati Shear machines at its Production Shop in Austin. California issued RFB-IS-26200650 for a shearing machine (due March 10, 2026) and RFB-IS-26201000 for a Water Table CNC Hypertherm Plasma Cutter (due June 11, 2026). The School Board of Polk County, Florida issued a vendor response request for integrated CNC training equipment (desktop mill, desktop lathe, industrial lathe, simulator, and tooling) due March 24, 2026. All recent solicitations emphasize firm, fixed-price bidding and electronic submission through state procurement portals (AggieBid, Euna, Sourcewell, or state-specific platforms).
