About Wassermann Stahl
Wassermann GmbH & Co. KG is a family-run company in Witten, now managed by the third generation since 1972, specializing in flame-cut parts, heavy plate and special steels. With more than 10,000 tonnes of material stored in halls and eight oxy-fuel cutting systems, the company produces cut blanks from 5 to 350 mm, complemented by plasma, laser and waterjet cutting. The product range covers top-quality (grade 1A) steels as well as price-optimized mill overrun volumes (wild dimensions) in S235 and S355, plus tested structural and special steels such as 42CrMo4, C45+N, S690QL, HB400–500, P265–P460 and the case-hardening steels 16MnCr5/20MnCr5. In addition, Wassermann offers finishing and service capabilities: blasting to Sa 2.5, stress-relief annealing and hardening and tempering, material analyses in its own laboratory for 14 chemical elements, ultrasonic testing to EN 10160, 3.2 inspections, re-stamping authorization and supplier declarations. Customers come among others from construction and infrastructure, mechanical and plant engineering, the automotive and transport industry, energy and environmental technology, and tool and equipment manufacturing. The company has operated its own flame-cutting facility since 1995; production at Plant 2 started in 2010.
