What Iwt-solutions Ag does

IWT-Solutions AG is a privately held German engineering consultancy based in Aachen that specializes in fracture mechanics, material testing, and steel qualification for safety-critical steel and cast-iron components. Founded around 2014 as a corporation (with predecessor activity dating to 1997 under founder Prof. Dr.-Ing. Peter Langenberg), the firm serves industrial clients, infrastructure operators, energy companies, steel manufacturers, and pressure-equipment owners that require component safety assessments, damage analysis, weldability reviews, and material qualification for legacy or new-build structures. Core service lines are organized around four pillars: fracture-mechanics services, material analysis, damage analysis, and hydrogen qualification (H2-Ready), supplemented by old-steel qualification, cryogenic testing down to -196°C, component testing, standardization consulting, and research/teaching collaborations with RWTH Aachen.

The firm's technical differentiator is the proprietary StIM/AIM© (Stahlidentifikationsmodul / Altstahl-Identifikationsmodul) method, a non-destructive identification system for historic steels that combines mobile optical emission spectroscopy (Hitachi PM Master Smart with UV Touch Probe) with curated expert knowledge. The methodology is validated for steels produced between 1870 and 1930, enabling steel reuse without invasive sampling. Capabilities are supported by specialized equipment including the Keyence VHX-7000 digital microscope (20x-2000x continuous magnification, 3D surface measurement, and web-conference integration for live client review), standard fracture-mechanics rigs, and cryogenic testing facilities for LNG-grade steels such as X8Ni9.

IWT-Solutions operates a sales-led, project-based B2B professional services model. Engagements are direct consulting commissions with industrial and government clients, delivered by a small expert team with deep ties to RWTH Aachen's Institute for Ferrous Metallurgy (IEHK). Pricing is not publicly disclosed but is consistent with specialized engineering consulting rates. The firm participates in European standardization work (DIN, EN 13445, EN 13480, CEN/TC) and in joint industry research, such as the IGF-funded iFrakto project on AI-based fractographic classification led by BAM and GFaI e.V. Geography is concentrated in the DACH region (Germany) with occasional pan-European engagements for hydrogen transport and offshore wind foundations.

Core offering

Iwt-solutions Ag is a German engineering services firm specializing in fracture mechanics, material testing, and steel qualification for industrial and infrastructure clients. The company delivers consulting, laboratory analysis, and qualification programs for components exposed to demanding service conditions, including hydrogen environments. It combines classical materials engineering with digital documentation and mobile analytics to support safety-critical decisions across the asset lifecycle.

Product overview

IWT-Solutions AG is a specialized engineering consultancy offering a unified portfolio of materials engineering and testing services centered on steel and cast-iron components. The core offering spans four interconnected pillars: Fracture Mechanics Services (crack toughness testing and lifetime analysis), Material Analysis (testing, microanalytics, digital microscopy), Damage Analysis (component, material, fire, and fatigue assessment), and Hydrogen Qualification (H2-ready material qualification for the hydrogen economy). Supporting these are Old Steel Qualification services (AIM© non-destructive steel identification via mobile OES), Cryogenic Testing (down to -196°C), Component Testing and Safety, and specialized consulting services including Training, Solution Engineering, Standardization Consulting, and Research & Teaching collaborations. The company uses advanced equipment including the Keyence VHX-7000 digital microscope and participates in AI-driven research projects (iFrakto) for automated fractographic analysis. The portfolio is delivered through direct consultancy engagements rather than a software platform, with strong academic partnerships (RWTH Aachen, THM Gießen) underpinning the technical methodology.
