What Bluewater Thermal does

Bluewater Thermal Solutions (BWT, LLC) is one of North America's largest commercial thermal processing providers, founded in 1990 and headquartered in Greenville, South Carolina. The company operates 11 facilities across the Northeast, Midwest, and Houston, Texas, delivering heat treating, brazing, and boronizing services to more than 2,000 customers in the automotive, aerospace, oil and gas, heavy equipment, agriculture, medical, and general industrial sectors. Bluewater is a portfolio company of Aterian Investment Partners, a private equity firm with offices in New York and Florida, and is led by CEO Patrick McKenna, who was appointed in July 2025 following senior leadership roles at Ipsen USA and as co-founder of Nevada Heat Treating and California Brazing.

The company's core technology portfolio spans three service categories: Core Solutions (hardening and tempering, carburizing, carbonitriding, normalizing, stress relieving, induction hardening, furnace and atmospheric brazing, and stainless steel annealing), Specialty Heat Treating (ferritic nitrocarburizing, age/precipitation hardening, nitriding, and solution annealing), and Boronizing Solutions (BOR-1CR boronized OCTG tubing and the newly launched Hard-Corr tubing product for oil and gas). Capital-intensive assets include continuous mesh belt furnaces, vacuum furnaces, induction hardening equipment, and custom car-bottom furnaces capable of processing parts up to 24 feet long. Bluewater is the largest supplier of boronized products to Bakken and Permian shale producers and is collaborating with Argonne National Laboratory on Ultra-Fast Boriding technology. Certifications held include NADCAP (South Bend, IN), AS9100-D, IATF 16949:2016 (Coldwater, MI), and ISO 9001:2015 across multiple facilities.

Bluewater generates revenue through a quote-based, per-job transaction model for industrial heat treating services, supplemented by value-added services (assembly, welding, plating, grinding, magnetic particle inspection, metallurgical laboratory testing, parts washing, packaging, and logistics via an in-house trucking fleet). The go-to-market motion is sales-led, with direct customer engagement via phone, web quote requests, and field sales, supported by a content marketing library of technical articles and case studies. Payment terms are net 30 days. Recent strategic activity has focused on commercializing Hard-Corr tubing (first order October 2025), expanding the executive team with a new CRO and CFO (April 2026), and deepening the technology pipeline through the Argonne partnership.

• Hard-Corr: Proprietary surface technology for tubing that imparts enhanced corrosion, wear, and erosion resistance to both inner and outer surfaces of tubing for oil and gas applications.

Products and services

• Hardening & Tempering Heat Treatment
• Carburizing & Carbonitriding Services Surface hardening processes that diffuse carbon (and nitrogen for carbonitriding) into steel components to create a hard, wear-resistant case while maintaining a tough core, for industrial manufacturers.
• Normalizing & Metal Stress Relieving Services Heat treatment processes that refine grain structure, reduce internal stresses, and improve machinability of metal components for industrial manufacturers.
• Induction Hardening Service Selective surface hardening process using electromagnetic induction to rapidly heat specific areas of metal components for precise hardness control, particularly effective for powdered metal parts at the Ridgway, PA facility.
• Furnace & Atmospheric Brazing Metal joining service using controlled atmosphere furnaces (including continuous mesh belt brazing) to create strong joints between dissimilar metals using filler metals with lower melting points, for automotive and industrial component manufacturers.
• Annealed Stainless Steel Heat treatment service for stainless steel components that restores ductility and reduces hardness for improved machinability and formability, for industrial manufacturers.
• Ferritic Nitrocarburizing Services (FNC) Low-temperature surface hardening process that diffuses nitrogen and carbon into ferrous materials to create wear-resistant surfaces with minimal distortion, for industrial manufacturers.
• Age Hardening / Precipitation Hardening Services Heat treatment process that strengthens metal alloys by forming precipitates within the microstructure, commonly used for aluminum, titanium, and nickel-based alloys, for industrial manufacturers.
• Nitriding Heat Treatment Surface hardening process that diffuses nitrogen into steel components to create a hard, wear-resistant case without quenching, minimizing distortion, for industrial manufacturers.
• Solution Annealing Service Heat treatment that dissolves alloying elements and re-precipitates them uniformly by heating to temperature and controlled cooling, used for stainless steel and alloy components in industrial applications.
• BOR-1CR Boronized Oil & Gas Tubing Boronizing/boriding surface treatment for oil country tubular goods (OCTG) that creates extremely hard, wear-resistant surfaces to extend component life in harsh downhole environments. Bluewater is the largest supplier of boronized products to Bakken and Permian shale producers.
• Hard-Corr™ Tubing Proprietary surface technology for L80-grade steel production tubing that imparts enhanced corrosion, wear, and erosion resistance to both inner and outer surfaces at a lower cost than boronized tubing, for oil and gas producers.
• Value-Added Services Comprehensive secondary operations including assembly, clamp tempering, press temper, component procurement, deburring, blasting, grinding, machining, magnetic particle inspection, metallurgical laboratory testing, plating, coating, packaging, parts washing, passivation, rust preventative, straightening, and trucking, often bundled with heat treating for one-stop solutions.
