Ilsenburger Grobblech GmbH, the heavy plate subsidiary of Salzgitter AG, has gained certificates for the military use of additional steel grades, it said May 13.
The company’s newly approved SECURE security steel grades will now cover approximately 80%-90% of the steel requirements for a military vehicle, allowing it to supply a wider range of components and protection concepts with certified material, marking a major milestone in its defense applications, it said.
Ilsenburger Grobblech completed a comprehensive approval campaign, certifying several steel grades for military use in accordance with Bundeswehr technical delivery conditions. The newly approved grades include: SECURE 400: 6-45 mm thickness; SECURE 450: 6-30 mm thickness; SECURE 500: 6-40 mm thickness, and SECURE 600: 6-22 mm thickness.
Previously, only SECURE 450 and SECURE 500 were certified, and only within limited thickness ranges. The broader certification range enhances the company’s competitiveness in European defense tenders, especially where local sourcing and approved materials are prioritized, it said.
Amid rising European defense spending, demand for certified heavy plate used in armored vehicles is increasing. The approvals reinforce the importance of qualification, traceability and performance standards in the defense steel market, the company said.
The company indicated that the initial scope for SECURE heavy plate had now been fulfilled.
