Stahlwerk Annahütte Max Aicher

What Stahlwerk Annahütte Max Aicher does

Stahlwerk Annahütte Max Aicher GmbH & Co. KG (SAH) is a German specialty steel manufacturer headquartered at Hammerau (Ainring), Bavaria, operating one of the world's oldest continuously running steel production sites, originally founded as an ironworks in 1537 and acquired by Dipl.-Ing. Max Aicher in 1975 out of bankruptcy. Since 2015 the firm has been owned by the Max Aicher Stiftung, a Bavarian foundation that also controls sister company Lech-Stahlwerke (EAF scrap-based steelmaking), Lech-Stahlveredelung, and other construction, real-estate, recycling, and tourism entities. SAH produces under two core brands: SAH Stabstahl (round steel bars in quality and engineering steel, with over 2,500 alloy grades) and SAS Systems Gewindestahl (warm-rolled threaded bar systems in 12–75 mm diameters, with over 2,800 system accessories), serving automotive, civil engineering, mining, tunneling, energy, tool, chain, and agricultural customers in more than 70 countries.

Production is built on a 22-stand fully continuous rolling mill (heats above 1,200 °C in pusher-type furnaces) supported by 10 finishing lines (adjustage), in-house heat treatment, and an unusual stack of testing equipment including a 5,000 kN tensile tester, a proprietary 4,000 kN relaxation test stand (sample lengths up to 9.0 m), a SincoTec high-frequency pulsator for fatigue testing, ultrasonic inspection, and Thermo Fisher ARL Quantris spark emission spectrometry. Approximately 98% of steel blooms are sourced from sister company Lech-Stahlwerke, whose electric arc furnace (EAF) scrap route delivers steel with roughly 80% lower CO2 and ~80% lower energy intensity than the conventional blast-oxygen-furnace route. SAH supplements this with two owned hydroelectric power stations covering up to 50% of facility electricity, a 425 kWp photovoltaic system installed in 2022, and a renewed walking-beam furnace commissioned in 2024 for additional energy and emissions reduction.

SAH generates revenue through direct hardware sales of finished steel products, both standardized and custom-configured (heat treatment, straightening, sawing, shot blasting, peeling, and surface finishing priced into each order), with pricing individually quoted based on alloy grade, dimensions, processing, and volume. Go-to-market is a technical enterprise sales motion run through the company's own international sales force and at least 12 wholly-owned regional subsidiaries (in Germany, Austria, France, Poland, Spain, Switzerland, Turkey, UAE, Singapore, Colombia, Panama, and the USA). Major named customer logos include all major European automotive manufacturers (rod steel used in gears, transmission shafts, chassis, and steering components) and headline infrastructure references such as the Gateway Bridge Brisbane, New World Trade Center, Daftha-Shis Tunnel Dubai, Kraftwerk Realp II Switzerland, Lotte Tower Seoul, and the Port of Eemshaven. The product set is qualified by extensive international certifications (ISO 9001/14001/45001/50001, IATF 16949, EN 1090-1/-2, ISO 3834, Lloyd's Register, DNV-GL, ICC-ES, Pressure Equipment Directive) plus a planned 2025 TISAX Level 2, which collectively act as the primary barrier to entry for civil engineering and safety-critical applications.
