What National Specialty Alloys does

National Specialty Alloys (NSA), founded in 1985 and headquartered in Houston, Texas, is a specialty metals processor and stocking distributor of premium stainless steel and nickel alloy bars and precision shapes. The company's core technical offering spans 17-4 stainless (in multiple conditions), 300 and 400 series stainless, A-286, Alloy 20, Duplex and Super Duplex, Nitronic 50 (XM-19) and Nitronic 60, plus nickel alloys 718, C276, K500, and 400 in various industry-spec conditions (AMS, NACE/API, ABS GR2). NSA's processing capabilities are centered on Pump Shaft Quality (PSQ) turning, grinding, and polishing — turning, grinding between centers, and precision straightening to tolerances tighter than industry norms — and extend through saw cutting, heat treatment, special machining, inside and outside diameter work, and comprehensive in-house testing including third-party Lloyd's and ABS certification. Custom marine shafts up to 32-38 feet long represent a signature capability developed through years-long R&D collaboration with shipbuilders.

The company operates a B2B enterprise field-sales model with offices and facilities in Texas (HQ), California, Georgia (sales), Louisiana (warehouse), and Cuautitlán, Mexico, reaching customers across 50 US states and 40 countries. Primary end markets are oil and gas, marine and shipbuilding, and medical and pharmaceutical equipment manufacturing, with secondary exposure to chemical processing, power generation, aerospace, desalination, mining, food processing, and pulp and paper. Pricing is custom quote-based with net-30 standard payment terms, supported by an ISO 9001:2015 quality management system (certified December 2023 through 2026). NSA is a wholly-owned subsidiary of Reliance, Inc. (NYSE: RS), the largest metals service center company in North America, with revenue figures not publicly disclosed at the subsidiary level.
