National Heat Treat

What National Heat Treat does

National Heat Treat, LLC is a commercial heat treating service provider founded in 2013 and headquartered at a 50,000-square-foot facility on Brittmoore Road in Houston, Texas. The company runs a diversified furnace fleet — including one of the largest commercial vertical vacuum furnaces in the region (72" diameter x 80" height working zone, 8,000 lb load capacity, up to 2400°F with integrated nitrogen/argon gas quench), five batch atmosphere furnaces with integral oil quench, three automated nitriding furnaces, two large car-bottom open fire furnaces, and seven box furnaces — and supports them with an in-house metallurgical laboratory. Service offerings span abrasive blasting, atmosphere processing, box furnace/oven operations, gas nitriding, open fire heat treating, vacuum heat treating, and testing and inspection (metallurgical analysis, mechanical testing, hardness testing, and non-destructive testing).

The business operates a sales-led, quote-based service model with standard 5-7 day turnaround and a premium 24-48 hour expedited tier; pricing is not publicly disclosed and varies by process, material, part complexity, and turnaround requirement. Free pickup and delivery across the Greater Houston area functions as both acquisition and retention lever, complemented by a dedicated Business Development Manager. Primary customer segments are Oil & Gas (downhole tools, drilling, threading) and Aerospace & Defense (where SAE AS9100D certification, achieved in 2019, is a prerequisite), with secondary exposure to Automotive, Energy/Power Generation, Tooling/Tool Steel, and small-to-mid machine shops. Revenue is generated through one-time service fees plus professional services for testing and inspection.

The company is privately held as a Texas LLC under an operating-partner ownership model, currently led by General Manager & Operating Partner Leo Martinez (35+ years thermal-processing experience) and Business Development Manager Brian Taylor (40+ years industry experience), supported by QA Manager Andy Mishaga and a management team with 100+ years of combined heat treating expertise. It is a member of the Metal Treating Institute and a corporate sponsor of ASM International's Houston Chapter. The company pursued legal action in 2018-2019 against Worldwide Heat Treat for trade secret violations, obtaining a Contempt of Court Order and monetary sanctions.

Products and services

• Abrasive Blasting Abrasive blasting service using steel shot or aluminum oxide to clean and prepare part surfaces for painting or other operations. Steel shot produces a polished appearance while aluminum oxide yields a matte finish.
• Atmosphere Processing Batch atmosphere furnace processing with integral oil quench for annealing, carbonitriding, carburizing, carbon restoration, hardening, normalizing, and solution annealing of metal parts.
• Box Furnace / Ovens Box furnace operations for tempering, annealing, and normalizing with seven furnaces capable of handling loads up to 3000 lbs at temperatures up to 1400°F.
• Gas Nitriding Surface hardening process that diffuses nitrogen into steel surfaces to create hard nitride particles, providing abrasion and wear resistance up to 70 HRC.
• Open Fire Heat Treating Furnace heat treating in an oxidizing atmosphere for aging, full annealing, hardening, normalizing, process annealing, solution annealing, and tempering operations.
• Vacuum Heat Treating Vacuum heat treating services including age hardening, bright annealing, furnace brazing, hardening, normalizing, stress relieving, tempering, and specialized processing for stainless steels and tool steels. Features one of the largest commercial vacuum furnaces in the region (72 inch diameter x 80 inch height).
• Testing and Inspection Comprehensive testing and inspection services including hardness testing, mechanical testing, metallurgical analysis, and non-destructive testing performed in-house or by qualified independent labs.
• Metallurgical Analysis On-site metallurgical laboratory services for microstructural examination, hardness testing, chemical analysis, and metallurgical consulting for material selection and failure analysis.
• Mechanical Testing Independent laboratory mechanical testing services including tensile testing, Charpy V-notch impact testing, stress rupture, and fatigue testing.
• Non-Destructive Testing NDT services including visual, dye penetrant, magnetic particle, ultrasonic, and radiographic testing performed on-site or offsite.
