APPLICATIONS FOR STEEL AND STAINLESS STEEL
Security & Defence Industry – Materials Solutions for the most Demanding Military Requirements
Whether for land, air or naval systems, Steel Defence Solutions develops and manufactures high-quality steel and stainless steel components for applications where reliability, materials expertise and security of supply are critical.
Requirements
Every Application has its own Requirements.
Every application places specific demands on materials, manufacturing and quality assurance. Steel Defence Solutions develops and supplies high-quality steel and stainless steel components for demanding defence projects – tailored to the technical, functional and safety-related requirements of each application.
Whether for land, air or naval systems, infrastructure or logistics, SDS combines European manufacturing, metallurgical expertise and an integrated value chain – from raw materials and melting through to fully machined finished products. The result is reliable components and assemblies for applications where mechanical strength, security of supply and long-term availability are essential.

Aerospace & Unmanned Aerial Systems (UAS)
Weapon Systems & High-Load Applications
Infrastructure & logistics
MARITIME APPLICATIONS
Maritime Security and Defence Industry
Saltwater exposure, corrosion and service lives spanning several decades place the highest demands on materials and manufacturing quality. Non-magnetic high-performance steel grades, for example, enable an extremely low magnetic signature, helping to minimise detectability. Drawing on decades of experience with high-alloy stainless steels, SDS develops durable components for maritime applications. Through obsolescence management, spare parts manufacturing and reproducible manufacturing processes, we also help ensure the long-term availability of safety-critical systems.
- Weldable stainless steel grades - Hull structures, pressure hulls and piping systems (e.g. 1.4317, 1.4468, 1.4469).
- Non-magnetic stainless steel grades - Submarines and mine countermeasure vessels (e.g. 1.3964, 1.3967).
- High-strength cast steel grades - Hull structures, topside structures and deck constructions (e.g. 1.6220).
- Corrosion-resistant stainless steel grades - Components exposed to permanent seawater contact (e.g. 1.4565).

LAND-BASED APPLICATIONS
Land-based Security and Defence Industry
Components for military land-based systems, including armoured vehicles and other defence platforms, must withstand extreme mechanical stresses, harsh and varying climatic conditions and prolonged operational deployment. Steel Defence Solutions develops and manufactures high-quality steel and stainless steel components and assemblies for demanding defence applications – from individual parts and prototypes to small-batch and series production. We support our customers throughout the entire value chain – from material selection to ready-to-install components, ensuring reliability, durability and long-term operational readiness.
