HTR GmbH

What HTR GmbH does

HTR GmbH (legal name HTR Rosenblattl GmbH) is an Austrian heat treatment services company headquartered in Thalheim/Wels, Upper Austria, operating since 2001 and integrated into the RICO GROUP industrial conglomerate in 2024. The company runs a job-shop model offering thermal processing of tool steels and specialty steels across four core service lines: hardening (vacuum, inert gas, induction, case hardening), nitriding (gas, plasma, salt bath), annealing (soft annealing, low-voltage annealing), and deep freezing / cryogenic treatment. Supporting services include material analysis, quality control, specialist consulting, customer seminars, and a branded 48-hour express service.

The customer base spans more than 1,000 industrial buyers across toolmaking and mechanical engineering, medical technology (dental, implants, surgical tools), automotive (commercial vehicles, passenger cars, motorbikes, racing), aerospace (including rocket tank components), and recycling/environmental technology. Distribution is regionally concentrated in central Upper Austria, served by a company-owned transport fleet that handles daily collection and delivery. Pricing is quote-based per job with no subscription or recurring component, and the GTM motion is sales-led direct industrial engagement with technical content marketing, seminars, and a quote-request funnel.

Operating leverage comes from certified process quality (ISO 9001, ISO 14001, ISO 45001, TÜV SÜD, EcoVadis), specialized equipment for niche processes such as plasma nitriding and salt bath nitriding, and metallurgical advisory talent that supports customers from the design phase. HTR functions as a specialty mid-market industrial services niche player rather than a high-growth technology business.

Functional benefit

Products and services

• Hardening Services Thermal hardening of steel and tool-steel components, offered through four methods: vacuum hardening (precise control in a vacuum environment), inert gas hardening (oxidation-free treatment under inert atmosphere), induction hardening (localized surface hardening via electromagnetic induction), and case hardening (surface hardening that retains a tough core). Used by toolmakers, mechanical engineers, and automotive suppliers.
• Nitriding Services Surface hardening via nitrogen diffusion, offered through three methods: gas nitriding (controlled gas atmosphere), plasma nitriding (ionized-gas plasma for precise surface treatment), and salt bath nitriding (molten salt bath for uniform surface hardening). Used by automotive, toolmaking, and medical technology customers requiring wear and corrosion resistance.
• Annealing Services Heat treatment to soften materials and relieve internal stresses, offered as soft annealing (reducing hardness and improving machinability) and low-voltage annealing (controlled heating using low voltage). Used by manufacturers preparing components for further machining or finishing.
• Deep Freezing Cryogenic treatment for dimensional stability and residual stress relief in tool steels and components. Used to improve dimensional stability and performance of hardened parts across toolmaking and mechanical engineering applications.
• 48h Express Service
